It contains information on how to use the HTC VIVE Tracker (2018)to enable position tracking and transmission of specific data(with or without the Htc Vive VR system VIVE Tracker(2018)can pair with HTC s wireless dongle or use its USB interface to transfer tracking data to a PC. An accessory attached to Vive Tracker(2018)can Simulate buttons of the vive controller through the underlying pogo pin Use cases There are five use cases supported by VivE Tracker (2018) Use Case 1: Track passive objects with a USB cable in VR. In this case, the dongle is not used, and VIvE Tracker(2018)connects with a pc by UsB directly to transfer tracking data USB VIVE Accessory Tracker Tracking data (2018) Figure: Use case 1 of VIVE Tracker (2018) Use Case 2: Track passive objects using a USB cable interface in VR, with the accessory passing data to a Pc through USB, BT/i-Fi or propriety RF. This case is similar to Use Case 1, but the accessory transfers data to pc directly for a specific purpose based on its design USB VIVE Accessory PC Tracker Tracking data USB, BT/iFi or accessory propriety RF ccessory data Figure: Use case 2 of V/VE Tracker(2018) Use Case 3: Track moving objects by wireless interface in VR.

Avoid placing the structure within the view angle, since it will block responses from VIVE Tracker (2018)sensors when placed in that direction If the docking part extends beyond the recommended placing cone, extra views will be blocked Extra blocked view angle by gun front Extra blocked view angle by gun handle Original blocked view angle Figure: Docking part extends beyond recommended placing cone HTC Confidential and Proprietary hTC VIVE Tracker(2018) Developer Guidelines HTC Corporation V1.0 03/14/2018 Docking The following are requirements for docking compatibility a. The docking design of VIVE Tracker (2018)follows the Iso standard(iso 1222: 2010) Furthermore, VIVE Tracker (2018) has constraining features, such as the longer screw cannot fasten all the way in b. The user should be able to easily attach and detach VIvE Tracker(2018)with two hands. One hand holds vive Tracker (2018), and the other one holds the accessory C. The user should not be at risk of physical harm while attaching or detaching VIVE Tracker (2018) d. The user should be comfortable while attaching and detaching VIVE Tracker(2018) e. The accessory attached with VIVE Tracker(2018)should be in the shape of a physical object to avoid hitting during operating VIVE Tracker(2018) should not be blocked by the accessory and affect the tracking performance g. It is strongly recommended that the accessory uses low reflection material for its outer skin to avoid reflection interference with the tracking sensors, especially if the accessory needs to be placed within the tracking sensors'Fov area Docking embodiments Gun Sword HTC Confidential and Proprietary
