The HTC Vive Tracker adds real-world objects to your virtual world. While these real-world objects in virtual environments are now mostly limited to a Nintendo Zapper for a Duck Hunt clone and a tennis racket, the future is clear: we’re going to be playing Duck Hunt and Wii Sports while wearing headsets. The future is so bright, it burns.
Of course, with any piece of neat computing hardware, there’s an opportunity for building an Open Source clone. That’s what [Drix] is doing with his Hackaday Prize entry. He’s created an Open Source Vive Tracker. It’s called the HiveTracker, and it is right now the best solution for tracking objects in a 3D space.
After a few missteps with ultrasonic and magnetic approaches, the team decided to piggyback on the HTC Vive lighthouses. These two base stations scan a laser beam across the room, first vertically, then horizontally. It’s an incredible piece of technology that [Alan Yates] talked about at the 2016 Hackaday Superconference.
While most microcontrollers don’t operate fast enough to see these laser sweeps, the team behind the HiveTracker found one microcontroller, with Bluetooth, and a feature called ‘PPI’. This programmable peripheral interconnect is kinda, sorta like a cross-bar, but designed for more real-time control of applications. With the right software, the team behind the HiveTracker was able to detect the lighthouses and send position and orientation data back to a computer.
This is a stupendous amount of work, and the results are remarkable. You can check out the video below and see that, yes, this is a real, Open Source Vive Tracker.
