While ultimately the goal is to be a general purpose hand\ntracking engine supporting any hand pose, the engine evolves\naround specific hand poses that users/developers find useful. These poses \nare detected by the engine which allows to build applications with meaningful interactions. \nSee the \u003ca href=\"https://handtracking-io.github.io/yoha/draw_demo\" target=\"_blank\"\u003edemo\u003c/a\u003e for an example.\n\nYoha is currently in beta.\n\nAbout the name: Yoha is short for (\"\u003cb\u003eYo\u003c/b\u003eur \u003cb\u003eHa\u003c/b\u003end Tracking\").\n\n## Language Support\n\nYoha is currently available for the web via JavaScript. More languages will be added\nin the future. If you want to port Yoha to another language and need help feel free reach out.\n\n## Technical Details\n\nYoha was built from scratch. It uses a custom neural\nnetwork trained using a custom dataset. The backbone for the\ninference in the browser is currently \u003ca\ntarget=\"_blank\" href=\"https://github.com/tensorflow/tfjs\"\u003eTensorFlow.js\u003c/a\u003e \n\n### Features:\n\n\u003cul\u003e\n  \u003cli\u003eDetection of 21 2D-landmark coordinates (single hand).\u003c/li\u003e\n  \u003cli\u003eHand presence detection.\u003c/li\u003e\n  \u003cli\u003eHand orientation (left/right hand) detection.\u003c/li\u003e\n  \u003cli\u003eInbuilt pose detection.\u003c/li\u003e\n\u003c/ul\u003e\n\n#### Supported Hand Poses:\n\n\u003cul\u003e\n  \u003cli\u003ePinch (index finger and thumb touch)\u003c/li\u003e\n  \u003cli\u003eFist\u003c/li\u003e\n\u003c/ul\u003e\n\nYour desired pose is not on this list? Feel free to create an \u003ca href=\"https://github.com/handtracking-io/yoha/issues/new/choose\"\u003eissue\u003c/a\u003e for it.\n### Performance\n\nYoha was built with performance in mind. It is able to provide realtime user\nexperience on a broad range of laptops and desktop devices. The performance\non mobile devices is not great which hopefuly will change with the further\ndevelopment of inference frameworks like \n\u003ca target=\"_blank\" href=\"https://github.com/tensorflow/tfjs\"\u003eTensorFlow.js\u003c/a\u003e\n\nPlease note that native inference speed can not be compared\nwith the web inference speed. Differently put, if you were to \nrun Yoha natively it would be much faster than via the web\nbrowser.\n\n## Minimal Example\n\n- [Source](https://github.com/handtracking-io/yoha/tree/main/example/)\n- Running locally:\n\n```\ngit clone https://github.com/handtracking-io/yoha \u0026\u0026 \\\ncd yoha/example \u0026\u0026 \\\nyarn \u0026\u0026 \\\nyarn start\n```\n\n## Drawing Demo\n\n- [Live Version](https://handtracking-io.github.io/yoha/draw_demo)\n- [Source](https://github.com/handtracking-io/yoha/tree/main/src/demos/draw)\n- Running locally:\n```\ngit clone https://github.com/handtracking-io/yoha \u0026\u0026 \\\ncd yoha \u0026\u0026 \\\n./download_models.sh \u0026\u0026 \\\nyarn \u0026\u0026 \\\nyarn start\n```\n\n","funding_links":[],"categories":["TypeScript"],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhandtracking-io%2Fyoha","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhandtracking-io%2Fyoha","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhandtracking-io%2Fyoha/lists"}
