Technology: Visions of holodecks

Haptic is the magic word today, specifically haptic technology or haptics. At root the word means:

adjective: of or relating to the sense of touch, in particular relating to the perception and manipulation of objects using the senses of touch and proprioception--the reception of stimuli produced within the organism.

Tactile is a related term and a number of groups are working on making devices that offer tactile experience.

Researchers at the University of Bristol have coined the word ultrahaptics to describe their project. This article from gizmag, New ultrasound research creates holographic objects that can be seen and felt, describes their current efforts. Here's a video that explains more.

Disney Research (Disney does research?) has a video about tactile rendering of 3D features on touch surfaces, from a project by the Pittsburgh research team. Their approach uses an electro-vibration based friction display. Here's the video published on the DisneyResearchHub channel.

Stuff, the magazine, reports on a prototype by Fujitsu that also uses ultrasonic haptic feedback, as does BIG's project.

Meanwhile MIT's Tangible Media Group is working on surfaces that actually change dimensionally. This video was published about six months ago on the MIT Media Lab channel.
