The parade of new VR/Immersive technology keeps on rolling.
Here is the newest solution for generating a hand avatar for an experience created by Manus Machina.
This seems like an alternative and competitor for technologies such as Leap. Leap uses optical tracking but devices such as this use actuators to track the hands position and rotation.
At the end of the day the best solution will be where the user does not have to keep his hands raised in front of him in order to operate the GUI. Gloves and optical tracking tech are cool but folks get tired after about a minute of raising their hands beyond hanging. Remind you that computers and even video games allow the user to rest their arms or wrists against some stationary surface. – Something to think about.
