 1 | # Text Emotion Detection using Gemini Nano(Integration with Chrome ) and React
 2 | 
 3 | # Usecase :
 4 | 
 5 | Difficulty understanding emotions in multiple modalities like Face , Speech and Text forms important markers in the diagnosis of Autism spectrum Disorder(ASD) . This Chrome extension aims to help autistic individuals identify emotions in Text using Gemini . 
 6 | 
 7 | This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
 8 | 
 9 | ## Demo Video
10 | 
11 | [gemini_nano.webm](https://github.com/user-attachments/assets/067bbf33-19ce-4daa-b563-a17e2a371932)
12 | 
13 | ## WorkFlow
14 | ![nano_new (1)](https://github.com/user-attachments/assets/6ef200aa-5a82-49fb-9c70-ca173900d1dc)
15 | 
16 | 
17 | ## Get this
18 | 
19 | Gemini nano is currently not supported to Chrome stable version, you need to install Chrome Canary
20 | 
21 | 
22 | After then, you should turn on these flags:
23 | * [chrome://flags/#prompt-api-for-gemini-nano](chrome://flags/#prompt-api-for-gemini-nano): `Enabled`
24 | * [chrome://flags/#optimization-guide-on-device-model](chrome://flags/#optimization-guide-on-device-model): `Enabled BypassPrefRequirement`
25 | * [chrome://components/](chrome://components/): Click `Optimization Guide On Device Model` to download the model.
26 | 
27 | > Note: The `Optimization Guide On Device Model` may not show up. What worked for me was opening the devtools and trying out the following:
28 | 
29 | > ```await ai.canCreateTextSession()```
30 | 
31 | After setting up, now you can clone this repo and run this
32 | 
33 | ## Available Scripts
34 | 
35 | In the project directory, you can run:
36 | 
37 | ### `npm start`
38 | 
39 | Runs the app in the development mode.\
40 | Open [http://localhost:3000](http://localhost:3000) to view it in your browser.
41 | 
42 | The page will reload when you make changes.\
43 | You may also see any lint errors in the console.
44 | 
45 | ### `npm test`
46 | 
47 | Launches the test runner in the interactive watch mode.\
48 | See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
49 | 
50 | ### `npm run build`
51 | 
52 | Builds the app for production to the `build` folder.\
53 | It correctly bundles React in production mode and optimizes the build for the best performance.
54 | 
55 | The build is minified and the filenames include the hashes.\
56 | Your app is ready to be deployed!
57 | 
58 | See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
