Picture by writer
explores how browser-based computational notebooks — significantly the WLJS Pocket book — can rework static slides into dynamic, real-time experiences. This strategy isn’t restricted to shows; you may put together interactive lecture notes for college kids or colleagues and publish it on net. For knowledge scientists, physicists, it highlights new methods to speak fashions, simulations, and visualizations, making advanced concepts extra intuitive and fascinating.
Is a PDF Sufficient?
Animations, bells and whistles, particularly the type that had been fashionable in PowerPoint 15–20 years in the past, have largely taken a backseat. Add to this the compatibility points between LibreOffice and MS Workplace (even between variations for Home windows and Mac), the presence or absence of obligatory fonts — and the will to do one thing uncommon on the “stage” fades away rapidly.
Take a look at fashionable technical shows: very often, it’s only a PDF doc consisting of pages with vector and raster graphics, and typically GIF animations that eat up megabytes (like this publish), with no mercy.
Unused Potential
It’s price separating ornamental bells and whistles from those who carry extra info in some media format. For instance, check out ECMA-363 [1] specification.

A 3D mannequin inside a PDF doc merely enhances the person/viewer expertise. You observe the thing from completely different angles/cross-sections.
It’s disappointing that such a characteristic is nearly nowhere supported apart from Adobe Acrobat and certain is not going to be. It appears like we made a leap prior to now, however now we have now returned to static slides.
Massive Scientific Convention DPG
DPG-Frühjahrstagung is a big European physics convention organized by the German Bodily Society (DPG) [2]. Yearly, they collect greater than 10^4
scientists and happen in German cities, protecting an unlimited array of physics fields.


There are such a lot of shows, and it lasts nearly per week, so by the top, it turns into too overwhelming. However, this doesn’t diminish its worth as a platform for networking, working towards shows, and a dependable strategy to be taught what’s at the moment available on the market, which trains have gone already, and that are simply departing.
The individuals in plenary classes are largely Grasp’s college students and PhD college students, with postdocs being rarer.
Such a big and accessible platform is a wonderful motivation to strive one thing new 💡 even when one thing might go unsuitable.
What’s a JoyCon?
Absolutely, the reader has seen gadgets like this:

This gadget acts as a slide switcher and typically as a laser pointer, connecting by way of Bluetooth or via a dongle. In any case, it’s a sort of controller with buttons. Controllers may be extra attention-grabbing — just like the one from the 2017 Nintendo Swap handheld console

It isn’t a lot larger, nevertheless it has some extra cool options:
- Analog stick 🕹️
- 11 buttons ☎️
- IR digital camera 📸 (troublesome to make use of, no good API documentation)
- Full IMU 🌐 (Inertial Measurement Unit) aka gyroscope with an accelerometer
- Bluetooth connectivity; acknowledged as a daily HID
The buttons can certainly be mapped to PowerPoint, or the stick can be utilized to regulate slides, emulating mouse or keyboard clicks, because it was carried out in these initiatives:
I assumed it could be cool to one way or the other use the IMU and analog stick. However for that, one would wish to transcend PowerPoint and PDF 🧙🏼♂️
Shifting Slides to Browser Setting
The thought behind this isn’t new, nevertheless it’s essential to keep in mind that this strategy might not work for everybody. Nevertheless, by transferring the presentation show and creation to the browser (significantly Javascript and HTML lands), we mechanically acquire entry to all the probabilities of contemporary net know-how: peripheral gadget help, JavaScript, CSS animation magic, and way more, together with video. It’s essential to notice that every one of that is cross-platform by default and can work nearly in every single place.
For instance, slides may be created in Markdown (or/and HTML) with the assistance of a easy framework (reasonably, a small library) RevealJS [5]
There’s additionally MDX-based presentation engines, and issues like Manim [6], Movement Canvas [7], however these guys require much more abilities to grasp.
The RevealJS API is sort of easy, so controlling the slides by way of JavaScript instructions is simple to implement:
setTimeout(() =>{
Reveal.navigateNext(1);
}, 1000)
Nevertheless, this direct strategy has vital drawbacks. It requires an web connection, and if you happen to’d choose to keep away from it, you’ll want to make use of bundlers (similar to Rollup) and embed all JavaScript libraries right into a single HTML file, as an example. Alternatively, you could possibly run a neighborhood net server.
Choice with Jupyter Pocket book
For those who like Python and IPYNB, then use nbconvert — it’s going to convert your pocket book immediately right into a RevealJS presentation, and also you gained’t even discover it! Or use the extension for Jupyter—RISE [8]

In any case, the concept stays easy — we have to one way or the other enter the net browser atmosphere to reap the benefits of all the probabilities of JoyCon.
Attempt it on Binder!
Choice with WLJS Pocket book
My opinion on WLJS [9] may be considerably biased as I’m one among its builders (and lively customers). This open-source IDE with a pocket book interface is extra tightly built-in with the net atmosphere, as slides usually are not exported there however are as an alternative executed and are simply one other sort of output cell, alongside the acquainted Markdown.

Below the hood, it additionally makes use of RevealJS however with a couple of further options:
- It really works offline
- It permits embedding interactive parts and parts, just like LaTeX Beamer
- It’s built-in with Wolfram Language (freeware distribution)
See extra about it in this story [10]. An final information on how one can make presentation there we revealed in our official weblog: Dynamic Presentation, or Learn how to Code a Slide with Markdown and WL [11].
Let’s Dive into JoyCon
So, the simplest choice is to make use of the already ready-made library joy-con-webhid [12]. Why spend time reinventing the wheel when folks have already carried out an amazing job for us?
npm set up joy-con-webhid --prefix .
All subsequent examples will probably be taken from the WLJS Pocket book. Nevertheless, you are able to do just about the identical factor utilizing Python + FAST API to interface with JavaScript or one thing related, and even simply use JS alone. The web model of the pocket book is obtainable right here [13].
First, let’s take heed to what’s coming from the controller port.
Code
.esm
import { connectJoyCon, connectedJoyCons } from 'joy-con-webhid';
// Create join button
const connectButton = doc.createElement('button');
connectButton.className = 'relative cursor-pointer rounded-md h-6 pl-3 pr-2 text-left text-gray-500 focus:outline-none ring-1 sm:text-xs sm:leading-6 bg-gray-100';
connectButton.innerText = "Join";
let connectionState = "Join";
let isJoyConConnected = false;
let lastUpdateTime = efficiency.now();
let isAllowedToConnect = false;
// foremost handler operate (warning! known as at 60FPS)
operate handleJoyConInput(element) {
const currentTime = efficiency.now();
if (currentTime - lastUpdateTime > 50) { // decelerate
lastUpdateTime = currentTime;
console.log(element);
}
}
// JoyCon periodically goes to sleep, we have to wake it up
const connectionCheckInterval = setInterval(async () => {
if (!isAllowedToConnect) return;
const connectedDevices = connectedJoyCons.values();
isJoyConConnected = false;
for (const joyCon of connectedDevices) {
isJoyConConnected = true;
if (joyCon.eventListenerAttached) proceed;
await joyCon.open();
await joyCon.enableStandardFullMode();
await joyCon.enableIMUMode();
await joyCon.enableVibration();
await joyCon.rumble(600, 600, 0.5);
joyCon.addEventListener('hidinput', ({ element }) => handleJoyConInput(element));
joyCon.eventListenerAttached = true;
}
updateConnectionState();
}, 2000);
// Replace button state
operate updateConnectionState() {
if (isJoyConConnected && connectionState !== "Related") {
connectionState = "Related";
connectButton.innerText = connectionState;
connectButton.fashion.background = '#d8ffd8';
} else if (!isJoyConConnected && connectionState !== "Join") {
connectionState = "Join";
connectButton.innerText = connectionState;
connectButton.fashion.background = '';
}
}
// Deal with click on occasion
connectButton.addEventListener('click on', async () => {
isAllowedToConnect = true;
if (!isJoyConConnected) {
await connectJoyCon();
}
});
// Simply decorations
const container = doc.createElement('div');
container.innerHTML = `Presenter controller`;
container.appendChild(connectButton);
container.className = 'flex flex-col gap-y-2 bg-white rounded-md shadow-md';
// Return DOM factor to the web page
this.return(container);
// When a cell received eliminated
this.ondestroy(() => {
cancelInterval(connectionCheckInterval);
});
An important operate right here is:
operate handleJoyConInput(element) {
const currentTime = efficiency.now();
if (currentTime - lastUpdateTime > 50) { // decelerate
lastUpdateTime = currentTime;
console.log(element); //output to the console
}
}
It appears to be like like there are numerous steps to do. In actuality, most of this code offers with connecting the controller and drawing a big “Join” button. Don’t pay an excessive amount of consideration to the particular strategies — they’ll simply get replaced with these obtainable in your particular atmosphere:
this.return(dom)
passes aDOMElement
for embedding on the web pagethis.ondestroy(operate)
callsoperate
when the cell is deleted, to wash up timers, and so on.- The primary line
.esm
is a strategy to specify the JavaScript cell subtype in WLJS Pocket book, which requires pre-bundling.
After we run this code cell, we’ll see the next:

Then observe these steps:
- Disconnect the controller from the Nintendo Swap (System → Controllers → Disconnect).
- Pair the JoyCon (R) with the PC by holding the small button on the aspect.
- Press “Join” on our presenter controller.
Opening the browser console, we reveal the next messages:
{
"buttonStatus": {
"y": false,
"x": false,
"b": false,
"a": false,
"r": false,
"zr": false,
"sr": false,
"sl": false,
"plus": false,
"rightStick": false,
"residence": false,
},
"analogStickRight": {
"horizontal": "0.1",
"vertical": "0.3"
},
"actualAccelerometer": {
"x": 0,
"y": 0,
"z": 0
},
"actualGyroscope": {
"dps": {
"x": 0,
"y": 0,
"z": 0
},
"rps": {
"x": 0,
"y": 0,
"z": 0
}
}
}
Numerous knowledge! Let’s strive utilizing this for the good thing about our presentation 💡
Buttons ☎️
To start, we will use two buttons to change slides

Within the WLJS pocket book, slides can be managed programmatically via a Wolfram wrapper operate that calls the RevealJS API.
FrontSlidesSelected["navigateNext", 1] // FrontSubmit
All that’s left is to set off this operate on the proper second when the button (or change) is clicked. To do that, occasions should be despatched from the Javascript world to the Wolfram machine, the place we will then do no matter we wish with them. This leads to the next diagram:

You don’t have to consider this, since it’s seamlessly carried out by way of APIs
Let’s return to the code cell and modify the handler.
Code
//....
//.......
const buttonStates = { //all buttons states on JoyCon (R)
a: false, b: false, residence: false, plus: false, r: false, sl: false, sr: false,
x: false, y: false, zr: false
};
const joystickPosition = [0.0, 0.0];
let restingJoystick = [0.0, 0.0];
let isCalibrated = false;
operate handleJoyConInput(element) {
if (!isCalibrated) { //calibration
restingJoystick = [Number(detail.analogStickRight.horizontal), Number(detail.analogStickRight.vertical)];
isCalibrated = true;
return;
}
const currentTime = efficiency.now();
if (currentTime - lastUpdateTime > 50) {
lastUpdateTime = currentTime;
let buttonPressed = false;
let joystickMoved = false;
for (const key of Object.keys(buttonStates)) {
if (!buttonStates[key] && element.buttonStatus[key]) buttonPressed = true;
buttonStates[key] = element.buttonStatus[key];
}
const verticalOffset = Quantity(element.analogStickRight.vertical) - restingJoystick[1];
const horizontalOffset = Quantity(element.analogStickRight.horizontal) - restingJoystick[0];
if (Math.abs(verticalOffset) > 0.1 || Math.abs(horizontalOffset) > 0.1) {
joystickMoved = true;
}
joystickPosition[0] = horizontalOffset;
joystickPosition[1] = -verticalOffset;
if (buttonPressed) {
for (const key of Object.keys(buttonStates)) {
if (buttonStates[key]) {
server.kernel.io.fireplace('JoyCon', true, key);
break;
}
}
}
if (joystickMoved) {
server.kernel.io.fireplace('JoyCon', joystickPosition, 'Stick');
}
}
}
//.......
//..
As you may see, we have now added a number of objects right here:
- Joystick calibration — analog sticks drift, so their digital place is rarely excellent
0.,0.
. - State of all buttons — why hammer the door each time if you happen to solely want to softly knock when the state adjustments? This reduces system stress.
- Sending states to the occasion pool — that is particular to WLJS, the place we ship knowledge to the Wolfram machine (or Python if you happen to’re in Jupyter).
The final level appears to be like like this (exchange with the equal in your atmosphere):
server.kernel.io.fireplace(String identify, Object state, String sample);
Then, on the Wolfram aspect, we will simply subscribe to those occasions like this
EventHandler["name", {
"pattern" -> Function[state,
Print[state];
]
}]
That is very handy, as Javascript sends the names of the pressed buttons because the sample. On this case, you may instantly subscribe to slip switching, for instance, like this:
- ZR — subsequent slide
- Y — again
Thus, programmatically controlling slides turns into intuitive:
EventHandler["JoyCon", {
"zr" -> (FrontSubmit[FrontSlidesSelected["navigateNext", 1]]&),
"y" -> (FrontSubmit[FrontSlidesSelected["navigatePrev", 1]]&)
}];
Let’s Check in Observe
Let’s create a easy presentation. Begin typing with
.slide
# Slide 1
__Hey Medium!__
---

Now, let’s join the JoyCon to the PC and hyperlink it to our Javascript script by urgent the Join button. Then, subscribe to the occasions as soon as within the lively session.
Now, simply run the cell with the slides:

Analog Stick 🕹️
The stick theoretically permits controlling two sliders concurrently. For the DPG Spring Conferences, I had the concept of a reside demonstration of a really peculiar impact m𝒶𝑔𝒾c𝑎𝓁 𝓌𝑜𝓇𝒹𝓈 𝒻𝓇𝑜𝓂 𝓅𝒽𝓎𝓈𝒾𝒸𝓈. I imagine that some ideas are way more impactful and understandable when demonstrated reside on stage.
Here’s a condensed code snippet for the interactive widget:
FaradayWidget := ManipulatePlot[
Abs[(E^(I w (-1 + Sqrt[1 + (f/((-I g - w) w + (d - w0)^2))])) + E^(I w (-1 + Sqrt[1 + (f/((-I g - w) w + (d + w0)^2))]))) /. {g -> 0.694, w0 -> 50.0}]
, {w, 20, 80}, {{f,2},0,100,1}, {{d,0},0,10,1}
, FrameLabel->{"wavenumber", "transmission"}
, Body->True
];
FaradayWidget
The interactive on-line model of this widget is obtainable right here [14]

To embed it in a slide, insert its image as a tag (just like JSX):
.slide
# Faraday Widget
Right here it's in motion
Now, let’s hyperlink it to our stick

To start with, let’s carry out a easy check and bind its place to a disk on the display:
pos = {0.,0.};
EventHandler["JoyCon", {"Stick" -> ((pos = #)&)}];
Graphics[{
Circle[{0,0}, 2.],
Disk[pos // Offload, 0.1]
}]

Clearly, the actions are too abrupt. Furthermore, making small changes is kinda painful utilizing JoyCon. The answer? Integration!
EventHandler["JoyCon", {"Stick" -> ((pos += 0.1 #)&)}];

Now, let’s hyperlink the pos
variable to the sliders of our widget:
FaradayWidget := ManipulatePlot[
Abs[(E^(I w (-1 + Sqrt[1 + (f/((-I g - w) w + (d - w0)^2))])) + E^(I w (-1 + Sqrt[1 + (f/((-I g - w) w + (d + w0)^2))]))) /. {g -> 0.694, w0 -> 50.0}]
, {w, 20, 80}, {{f,2},0,100,1}, {{d,0},0,10,1}
, FrameLabel->{"wavenumber", "transmission"}
, Body->True
, "TrackedExpression" -> Offload[5 pos] (* <-- *)
];
Right here’s the way it appears to be like reside on a slide:

And within the precise DPG presentation:

A Second of Relaxation
Final yr, DPG passed off in Berlin, and this yr — in Regensburg, which has about 23 instances fewer inhabitants and is 10 instances smaller in space. Nevertheless, the comfortable lands of Bavaria have all the time been nearer to my ❤️

And that is the college. A strong 60s-style constructing. Wha 💪🏻

A brand new invention — a cup “Drink and Eat Me”

As a bonus, each drink will get a touch of waffle taste! However, be careful — don’t chunk into it whereas it’s stuffed with scorching tea.
I couldn’t take extra images since I received sick on the primary day and went again residence to Augsburg. Typically, spending six days at a convention is sort of difficult.

Again to enterprise 🐏
IMU or Gyroscope-Accelerometer Mixture 🌐
To make use of them, we have to learn the corresponding fields from the particulars
object, particularly:
- actualAccelerometer: x, y, z
- actualGyroscope: rps (radians per second)
Code
//..
//....
const buttonStates = {
a: false, b: false, residence: false, plus: false, r: false, sl: false, sr: false,
x: false, y: false, zr: false
};
const joystickPosition = [0.0, 0.0];
let restingJoystick = [0.0, 0.0];
let isCalibrated = false;
let imuEnabled = false;
// Allow IMU mode if allowed
core.JoyConIMU = async (args, env) => {
imuEnabled = await interpretate(args[0], env);
};
// Operate to deal with Pleasure-Con enter
operate handleJoyConInput(element) {
if (!isCalibrated) {
restingJoystick = [Number(detail.analogStickRight.horizontal), Number(detail.analogStickRight.vertical)];
isCalibrated = true;
return;
}
const currentTime = efficiency.now();
if (currentTime - lastUpdateTime > 50) { // Replace each 50ms
lastUpdateTime = currentTime;
let buttonPressed = false;
let joystickMoved = false;
for (const key of Object.keys(buttonStates)) {
if (!buttonStates[key] && element.buttonStatus[key]) buttonPressed = true;
buttonStates[key] = element.buttonStatus[key];
}
const verticalOffset = Quantity(element.analogStickRight.vertical) - restingJoystick[1];
const horizontalOffset = Quantity(element.analogStickRight.horizontal) - restingJoystick[0];
if (Math.abs(verticalOffset) > 0.1 || Math.abs(horizontalOffset) > 0.1) {
joystickMoved = true;
}
joystickPosition[0] = horizontalOffset;
joystickPosition[1] = -verticalOffset;
if (imuEnabled) {
server.kernel.io.fireplace('JoyCon', {
'Accelerometer': Object.values(element.actualAccelerometer),
'Gyroscope': Object.values(element.actualGyroscope.dps)
}, 'IMU');
}
if (buttonPressed) {
for (const key of Object.keys(buttonStates)) {
if (buttonStates[key]) {
server.kernel.io.fireplace('JoyCon', true, key);
break;
}
}
}
if (joystickMoved) {
server.kernel.io.fireplace('JoyCon', joystickPosition, 'Stick');
}
}
}
//....
//..
Since IMU shouldn’t be all the time wanted, the script features a boolean variable and a management operate JoyConIMU[True | False]
, permitting IMU measurements to be enabled or disabled.
The JoyCon, like most different gadgets with IMU (some smartphones, watches, however positively not VR headsets or quadcopters), consists of:
- 3-axis gyroscope — returns angular velocity in rad/sec round all three axes
- 3-axis accelerometer — returns a single acceleration vector
Query: Why can’t we use solely a gyroscope or an accelerometer?
Let’s strive outputting each. First, allow IMU utilization:
JoyConIMU[True] // FrontSubmit;
Now, outline auxiliary capabilities and variables:
prevTime = AbsoluteTime[];
angles = {0,0,0};
acceleration = {0,0,-1};
course of[imu_] := With[{time = AbsoluteTime[]},
With[{dt = time - prevTime},
angles = (angles + {-1,1,1} imu["Gyroscope"][[{3,1,2}]] dt);
acceleration = imu["Accelerometer"];
prevTime = time;
]
]
What occurs right here:
- The accelerometer vector is just saved in
acceleration
. - Gyroscope knowledge is processed by:
- Reordering angular velocity values (JoyCon {hardware} orientation) and adjusting instructions.
- Integrating over time to acquire orientation angles
Because of this, we acquire:
- Three angles defining JoyCon orientation
angles
. - One acceleration vector (at relaxation — the gravity path)
acceleration
.
These three angles are conveniently expressed as a matrix (tensor):
RollPitchYawMatrix[{[Alpha], [Beta], [Gamma]}] // MatrixForm
Making use of this matrix to any 3D object permits it to be oriented based on these angles. Bodily, on the JoyCon, it appears to be like like this:

It is very important be aware that since we measure solely the primary by-product (utilizing Gyro), then the preliminary IMU orientation stays unknown. Due to this fact, we manually set the preliminary state, i.e.
angles = {0., 0., 0}
EventHandler["JoyCon", {
"IMU" -> Function[val,
process[val];
]
}];
angles = {0,0,0}; (* calibration *)
Refresh[acceleration, 0.25] (* dynamically replace *)
Refresh[angles, 0.25] (* dynamically replace *)
Actual-time Information Output:

Nicely… Not fairly apparent what these values imply. Let’s strive to attract then as vectors in 3D area:
axis = Desk[{{0.,0.,0.}, Table[1.0 KroneckerDelta[i, j], {i,3}]}, {j,3}];
EventHandler["JoyCon", {
"IMU" -> Function[val,
process[val];
axis[[1]] = {{0.,0.,0.}, RollPitchYawMatrix[angles].{0,1.0,0.0}};
axis[[2]] = {{0.,0.,0.}, RollPitchYawMatrix[angles].{-1.0,0.0,0}};
axis[[3]] = {{0.,0.,0.}, -Normalize[acceleration][[{2,1,3}]]};
axis = axis;
]
}];
After which render them as coloured cones, the place:
- Blue and pink — defines angles derived from the gyroscope knowledge
- Inexperienced — accelerometer knowledge (inverted and normalized)
{
{Opacity[0.2], Sphere[]},
Pink, Tube[axis[[1]]//Offload, {0.2, 0.01}],
Blue, Tube[axis[[2]]//Offload, {0.2, 0.01}],
Inexperienced, Tube[axis[[3]]//Offload, {0.2, 0.01}]
} // Graphics3D
EventHandler[InputButton["Reset"], Operate[Null, angles *= .0]]

The inexperienced vector is all the time aligned “accurately,” whereas the blue and pink vectors, representing gyroscope angles, accumulate errors over time, particularly with fast actions, inflicting drift.
There are numerous methods to unravel this concern. The overall thought is to regulate the angles utilizing accelerometer knowledge (inexperienced vector), because the accelerometer exactly determines the downward path ( till an exterior pressure disturbs it).
For a extra detailed clarification, take a look at an amazing video by James Lambert [15], which explores these issues and their options, together with a detailed instance with Oculus DK1.
Why the heck do we’d like this within the presentation?
I requested myself this query once I found how deep the rabbit gap goes. In my speak on the magnetism session, there was precisely one slide the place the concept of an IMU made any sense:

Do you see the crystalline construction? Discovering a “good” digital camera angle for it’s certainly troublesome, so why not rotate it immediately, energetic? We don’t want all three angles and acceleration-just one will suffice.
Thus, we discard the accelerometer and maintain solely the gyroscope:
FrontSubmit[JoyConIMU[True]];
timestamp = AbsoluteTime[];
angle = 0.;
rotation = RotationMatrix[angle, {0,0,1.0}];
EventHandler["JoyCon", {
"IMU" -> Function[val,
With[{angularSpeed = val["Gyroscope"][[1]], time = AbsoluteTime[], oldAngle = angle},
angle += (time - timestamp) angularSpeed;
timestamp = time;
];
rotation = RotationMatrix[angle, {0,0,1.0}];
]
}];
Now, we simply want to use the rotation

Let’s embed it into our slide:
.slide
# Slide
Right here is my crystal construction!

To make it much more handy, it could be helpful to subscribe to IMU solely when the slide is lively and unsubscribe when leaving it. That is straightforward to do as a result of RevealJS alerts the core on slide state change occasions. Let’s implement this as a part utilizing .wlx
cell sort:
.wlx
InteractiveCrystalStructure := Module[{rotation = RotationMatrix[1Degree, {0,0,1.0}], id = CreateUUID[], timestamp = AbsoluteTime[], angle = 0., CrystalStructure},
CrystalStructure = Graphics3D[
GeometricTransformation[CrystalRawStructure, rotation // Offload]
, ViewPoint->3.5{1.0,0.5,0.5}
, ImageSize->{550,600}
];
EventHandler[id, {
"Slide" -> Function[Null,
FrontSubmit[JoyConIMU[True]];
EventHandler["JoyCon", {
"IMU" -> Function[val,
With[{angularSpeed = val["Gyroscope"][[1]], time = AbsoluteTime[], oldAngle = angle},
angle += (time - timestamp) angularSpeed;
timestamp = time;
];
rotation = RotationMatrix[angle, {0,0,1.0}];
]
}];
],
("Destroy" | "Left") -> Operate[Null,
FrontSubmit[JoyConIMU[False]];
]
}];
]
By putting this code on any slide, we obtain the specified end result with out polluting the worldwide area or interfering with different occasion handlers. Thus, IMU subscription administration is localized to the precise slide, and when switching slides, we accurately allow and disable knowledge dealing with with out affecting different slides and their processing

No analysis is required (don’t run it ;)). Merely disguise the enter cell, leaving solely the output seen via the properties (click on on the top-right nook of the group).
Here’s a pocket book with all examples [13] (a few of which work in a browser as effectively with out a kernel).
What if utilizing my very own laptop computer shouldn’t be an choice?
The WLJS Pocket book may be exported to HTML, preserving even some dynamic conduct [16]. That is achieved via a fairly subtle algorithm that tracks all occasion chains occurring on the JS and WL sides, making an attempt to approximate them utilizing a easy state machine. The result’s a typical HTML file containing all cells, slides, and the information of those state machines.
Nevertheless, as a result of number of values acquired from the IMU, the exporter can not mechanically seize this in a JS state machine. Consequently, rotations and the joystick enter is not going to be preserved. Nonetheless, all the pieces else will operate as anticipated. 🙂

Please seek advice from the ultimate sentence of that stunning comics by
Zach Weinersmith.
If not for the pressing must showcase a rotating crystalline construction, this publish wouldn’t exist.
Thanks to your consideration, and to those that learn this far 🧙🏼♂️ 🤍
