    Surround Haptics, a new tactile technology developed at Disney Research, Pittsburgh (DRP) in collaboration with Carnegie Mellon University, makes it possible for video game players and film viewers to feel a wide variety of sensations, from the smoothness of a finger being drawn against skin to the jolt of a collision. The technology is based on rigorous psychophysical experiments and new models of tactile perception. The technology will enhance a high-intensity driving simulator game developed in collaboration with Disney's Black Rock Studio. With players seated in a chair outfitted with inexpensive vibrating actuators, Surround Haptics will enable them to feel road imperfections, objects falling on the car, skidding, braking and acceleration; and experience ripples of sensation when cars collide. They will also experience jumping, flying, falling, shrinking or growing, of bugs creeping on their skin, the researchers said. The DRP researchers have accomplished this feat by designing an algorithm for controlling an array of vibrating actuators in such a way as to create "virtual actuators" anywhere within the grid of actuators. A virtual actuator can be created between any two physical actuators; the user has the illusion of feeling only the virtual actuator, the researchers said. As a result, users don't feel the general buzzing or pulsing typical of most haptic devices today, but can feel discrete, continuous motions such as a finger tracing a pattern on skin. Disney is demonstrating Surround Haptics Aug. 7-11 at the Emerging Technology Exhibition at SIGGRAPH 2011, the International Conference on Computer Graphics and Interactive Techniques in Vancouver, B.C.

  • This kind of disease modeling could have a great impact in the near term, says MIT professor Sangeeta Bhatia, who is developing liver tissue to study hepatitis C and malaria infection.
  • liver is difficult to grow outside the human body because cells tend to lose their function when they lose contact with neighboring cells. “
  • In a large-scale project recently funded by the Defense Advanced Research Projects Administration, several MIT faculty members are working on a “human-on-a-chip” system that scientists could use to study up to 10 human tissue types at a time.

  • Endothelial cells, normally found lining blood vessels, could help repair damage caused by angioplasty or other surgical interventions; smoke inhalation; and cancer or cardiovascular disease.
  • One of the earliest successes of implantable tissues was the development of artificial skin, which is now commonly used to treat burn victims.
  • Langer is now working on more complex tissues, such as cardiac-tissue scaffolds that include electronic sensors and a synthetic polymer that could restore vocal-cord function in people who have lost their voices through overuse or other types of damage
  • In Bhatia’s lab, where tissue-engineering research is evenly divided between modeling diseases and working toward implantable organs, researchers recently developed 3-D liver tissues that include their own network of blood vessels
