Haptics

Haptics or Tactile feedback is a technology that produces the sense of touch through physical stimulation. Haptics can improve the user's immersion in a VR world. It allows users to experience physical sensations caused by their actions in a virtual environment. When a user picks up a cup in the virtual world, the user should feel the realistic sensations of a cup in his or her hand. Even though the cup is not present in the real world.

In traditional video game controllers, "rumble" is often used to produce tactile feedback.

Development

In SIGGRAPH technology conference, Japanese scientists Tomohiro Amemiya and Hiroaki Gomi demonstrated 2 Force display devices: Traxion and Buru-Navi3. When held, these devices can cause push and pull sensations while vibrating in place.
