aid: ultraleap name: Ultraleap description: >- Ultraleap Limited (Bristol, UK) is the hand-tracking and mid-air haptics company formed in 2019 when Ultrahaptics acquired Leap Motion. It ships the Leap Motion Controller 2 and Stereo IR 170 / 3Di hand-tracking cameras, the Ultraleap Hand Tracking Software (Gemini V5, now Hyperion V6) with its native LeapC C API, first-party Unity and Unreal plugins, an implicit OpenXR API layer implementing XR_EXT_hand_tracking, Python bindings, a LeapJS-compatible tracking WebSocket server, and the TouchFree touchless interaction tooling for web and Unity. Its ultrasonic haptics SDK is supplied on request rather than published. The developer surface is a locally installed SDK and service, not a hosted HTTP API, so there is no OpenAPI or base URL. In 2025 the company announced it is joining ROLI, the music-technology company. image: https://avatars.githubusercontent.com/u/51484212?v=4 url: https://raw.githubusercontent.com/api-evangelist/ultraleap/refs/heads/main/apis.yml x-type: company x-source: harvest:secondary-market x-tier: stub x-tier-reason: harvest specificationVersion: '0.20' created: '2026-09-18' modified: '2026-09-18' tags: - Company - Hand Tracking - Computer-Vision - Spatial Computing - Haptics - Augmented Reality - Virtual Reality - XR - Gesture Recognition - OpenXR - SDK - Hardware - Human-Computer Interaction tags_raw: - Company - Hand Tracking - Computer Vision - Spatial Computing - Haptics - Augmented Reality - Virtual Reality - XR - Gesture Recognition - OpenXR - SDK - Hardware - Human Computer Interaction apis: - aid: ultraleap:leapc-tracking-api name: LeapC Tracking API description: >- LeapC is the native C API of the Ultraleap Hand Tracking Software. A client opens a connection to the locally running tracking service and polls it for tracking frames (hands, palms, digits, bones), device events, image frames, policy and configuration responses, plus the Hyperion V6 hinting, marker-tracking and direct-camera-access surfaces. It is the layer the Unity, Unreal, OpenXR and Python bindings are built on. There is no hosted HTTP base URL; the transport is local IPC to the tracking service. humanURL: https://docs.ultraleap.com/api-reference/tracking-api/index.html tags: - Hand Tracking - Native API - C properties: - type: Documentation url: https://docs.ultraleap.com/api-reference/tracking-api/leapc-guide.html - type: APIReference url: https://docs.ultraleap.com/api-reference/tracking-api/api-reference.html - type: Examples url: https://docs.ultraleap.com/api-reference/tracking-api/examples.html - type: ReleaseNotes url: https://docs.ultraleap.com/hand-tracking/Hyperion/index.html - aid: ultraleap:openxr-api-layer name: Ultraleap OpenXR API Layer description: >- An implicit Khronos OpenXR API layer, installed with the Hand Tracking Software, that serves XR_EXT_hand_tracking, XR_EXT_hand_joints_motion_range, XR_EXT_hand_tracking_data_source, XR_MSFT_hand_interaction, XR_ULTRALEAP_hand_tracking_forearm, XR_ULTRALEAP_hand_tracking_hints and XR_FB_hand_tracking_aim to any OpenXR application without code changes. humanURL: https://docs.ultraleap.com/openxr/index.html tags: - OpenXR - Hand Tracking - XR properties: - type: Documentation url: https://docs.ultraleap.com/openxr/index.html - type: ChangeLog url: https://docs.ultraleap.com/openxr/changelog/index.html - type: SourceCode url: https://github.com/ultraleap/OpenXRHandTracking - aid: ultraleap:tracking-websocket name: Ultraleap Tracking WebSocket description: >- An open-source WebSocket server from Ultraleap that restores the LeapJS-compatible surface removed when Leap Motion Orion V4 was replaced by Ultraleap Gemini V5. It streams tracking data over the legacy LeapJS v6 JSON protocol so browser applications can consume hand tracking. It runs locally alongside the tracking service; the endpoint is a loopback WebSocket, not a hosted API. humanURL: https://github.com/ultraleap/UltraleapTrackingWebSocket tags: - WebSocket - Streaming - Browser properties: - type: SourceCode url: https://github.com/ultraleap/UltraleapTrackingWebSocket - type: Documentation url: https://github.com/ultraleap/UltraleapTrackingWebSocket/blob/main/README.md - aid: ultraleap:touchfree-tooling name: TouchFree Tooling description: >- TouchFree turns Ultraleap hand tracking into touchless cursor and gesture input for kiosks, digital signage and existing 2D user interfaces.
