Here is a clever haptic feedback device that projects sensations through the air using ultrasound. The STRATOS Explore is designed to make interacting with VR objects more realistic. It gives users feedback from mid-air gestures.
The STRATOS Explore lets you create complex haptic sensations. It has a software development kit for C# and C++. It also has a sensation editor and Unity plugin. Hand tracking is done with a Leap Motion camera module.
