(Don't include 184 | the brackets!) The text should be enclosed in the appropriate 185 | comment syntax for the file format. We also recommend that a 186 | file or class name and description of purpose be included on the 187 | same "printed page" as the copyright notice for easier 188 | identification within third-party archives. 189 | 190 | Copyright [yyyy] [name of copyright owner] 191 | 192 | Licensed under the Apache License, Version 2.0 (the "License"); 193 | you may not use this file except in compliance with the License. 194 | You may obtain a copy of the License at 195 | 196 | http://www.apache.org/licenses/LICENSE-2.0 197 | 198 | Unless required by applicable law or agreed to in writing, software 199 | distributed under the License is distributed on an "AS IS" BASIS, 200 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 201 | See the License for the specific language governing permissions and 202 | limitations under the License. -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # Cam Scroller 2 | 3 | Cam Scroller is an open-source Chrome extension that uses your webcam and 4 | [deeplearn.js](https://deeplearnjs.org) to enable scrolling through webpages 5 | using custom gestures that you define. 6 | 7 | The Chrome extension can be found in the Chrome web store at this link: https://chrome.google.com/webstore/detail/cam-scroller/egljnginfcbpehnpfojpbogiopdgjjak 8 | 9 | It makes use of the deeplearn.js [KNN image classifier](https://github.com/PAIR-code/deeplearnjs/blob/master/models/knn_image_classifier/knn_image_classifier.ts) 10 | in the same manner as [Teachable Machine](https://teachablemachine.withgoogle.com/) 11 | and [Cam Arcade](https://deeplearnjs.org/demos/teachable_gaming/). 12 | 13 | In doing so, your webcam images are processed locally on your machine and at no 14 | time is any information collected or sent externally. 15 | 16 | This simple Chrome extension is meant to show, through a minimal example, the 17 | types of experiences that can be enabled through the use of browser-based 18 | machine learning. 19 | 20 | ![GIF showing training process](https://gist.githubusercontent.com/jameswex/d9506ffef04976e37d577e2907cac276/raw/38ef1cd3a60e0f3a4db56b93c87470a51c3eda45/CamScrollerTraining.gif) 21 | 22 | ## Usage 23 | 24 | ### How to install and configure the extension 25 | 26 | 1. Install the extension from the Chrome store. 27 | 1. Upon initial installation, the extension will ask for permission to access 28 | the webcam. After granting permission, you can close the welcome page. 29 | * Note that the extension keeps your webcam open, but at no point is any 30 | information from the webcam ever sent anywhere. All processing happens local 31 | to your machine. 32 | 1. Click the Cam Scroller browser action icon next to the address bar. In the 33 | popup, you should see a display of what your webcam is seeing. Click the "Create 34 | scrolling gestures" button and follow the on-screen instructions to create your 35 | custom scrolling gestures. 36 | * You will be asked to train three different poses: one for scrolling down, 37 | one for scrolling up, and one for the steady state of not scrolling at all. 38 | 39 | From this point on, for any new tab/page you load, scrolling can be 40 | controlled by the gestures you trained. You will see a visual scrolling 41 | indicator on the right side of the page when scrolling is being controlled by 42 | your gestures. 43 | 44 | The KNN image classifier weights for the trained gestures are stored in 45 | Chrome local storage, so the gestures do not have to be retrained when you 46 | close and then relaunch Chrome. 47 | 48 | ### Controls available in the extension 49 | 50 | If you want to temporarily turn off the Cam Scrolling capability, 51 | uncheck the checkbox in the Cam Scroller browser action popup. 52 | 53 | If at any time you wish to retrain the gestures, just click the "Create 54 | scrolling gestures" button again in the extension popup. 55 | 56 | ## Code breakdown 57 | 58 | welcome.[html/js] - Page launched on initial extension installation which 59 | requests webcam access for the extension. 60 | 61 | popup.[html/js] - Browser action popup page. Displays the webcam and has 62 | controls for training the scrolling gestures and enabling/disabling scrolling. 63 | Passes messages to the background page to do the actual processing. 64 | 65 | background.[html/js] - Contains all the machine learning logic for the 66 | extension. Trains the KNN image classifier when in training mode, infers which 67 | scrolling gestures are being performed when in inference mode, and sends 68 | messages to the content script to perform scrolling. 69 | 70 | content.js - Content script running with webpages loaded in Chrome. Calls 71 | window.scrollBy to scroll webpages and places visual indicators on the page when 72 | scrolling. 73 | 74 | ## Notice 75 | 76 | This is not an officially supported Google product. 77 | -------------------------------------------------------------------------------- /background.html: -------------------------------------------------------------------------------- 1 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | -------------------------------------------------------------------------------- /background.js: -------------------------------------------------------------------------------- 1 | /** 2 | * Copyright 2018 Google LLC 3 | * 4 | * Licensed under the Apache License, Version 2.0 (the 'License'); 5 | * you may not use this file except in compliance with the License. 6 | * You may obtain a copy of the License at 7 | * 8 | * https://www.apache.org/licenses/LICENSE-2.0 9 | * 10 | * Unless required by applicable law or agreed to in writing, software 11 | * distributed under the License is distributed on an 'AS IS' BASIS, 12 | * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 13 | * See the License for the specific language governing permissions and 14 | * limitations under the License. 15 | */ 16 | 17 | const math = new dl.NDArrayMathGPU(); 18 | const NUM_CLASSES = 3; 19 | const K = 5; 20 | const knn = new knn_image_classifier.KNNImageClassifier(NUM_CLASSES, K, math); 21 | 22 | // Do first-time setup to gain access to webcam, if necessary. 23 | chrome.runtime.onInstalled.addListener((details) => { 24 | if (details.reason.search(/install/g) === -1) { 25 | return; 26 | } 27 | chrome.tabs.create({ 28 | url: chrome.extension.getURL('welcome.html'), 29 | active: true 30 | }); 31 | }); 32 | 33 | // Mapping of training commands to KNN class indices.
