The stand is called the Star Accessory, and it uses a marker to track. Roration will work up to 180 degrees, and it works as long as the tracker is within 8 meters (26 feet) away. Currently the device only rotates on a horizontal axis, but they working on implementing a vertical axis as well.
The Satarii team recently surpassed their $20,000 funding goal, and that means this stand will be a real product in the near future. Most of their funding came from crowdsourcing, so they’ve kept their development progress very public and up to date.
Their promotional YouTube video explains it best, so without further ado here it is!
