Inconsistent Kinesthetic Feedback

Kinesthetic Feedback, otherwise known as proprioception, is feedback relating to the position of the user's body, and the movements they have just performed, based on feedback from their nerve endings into the central nervous system.

When hooked into a virtual environment, proprioception is key to the user believing they are in that avatar body and moving it around as their own. However, if the kinesthetic feedback is incomplete or inconsistent, it creates the opposite problem. The user is faced with a choice; a limited range of movements which feedback that they are actually in that body, or other movements which interfere with the feeling of being in that body, or interface components that break the realism and feel unnatural; remind the user that this is a simulation.

Packbot to gain Haptic Feedback
In October 2009, iRobot announced that they would be receiving additional funding from the US Robotics Technology Consortium. They plan to use much of this money to add full haptic feedback technology to their heavy-duty robots.

VR Interfaces: Shimi
Shimi is the product of research done at Georgia Tech's Center for Music Technology. It is, in essence, an artificial intelligence DJ. It recommends songs, dances to the beat and keeps the music pumping based on listener feedback.

You Tube of the first haptic, bionic arm versus a non-haptic
A comparison. Two women, both with prosthetic limbs. On the left, a standard prosthetic. On the right, a haptic prosthetic giving touch feedback. Who can complete the task faster, and is there much difference?

Damaging Education with Virtual Environments: BarbieGirls
BarbieGirls is quite possibly a very sick and twisted virtual world. It is ironically making use of the power of the interactive medium which comprises virtual reality. It has great power to educate and inform, to engage the participant, with positive feedback and reinforcement.

Touchscreen Use in All Weather

Touchscreen technology has until now, had one strong disadvantage: In inclement weather, wet, freezing cold hands result from touchscreen use, as gloves and other finger protectors have always made fingers too big and bulky to effectively use touchscreen technology, whilst masking tactile feedback with the glove?s spongy surface.

Powering The Augmented Form
Virtual reality environments tying directly into the neurons of the human brain. Worlds offering a better life, a happier life, providing feedback directly to your body. Embedded medical devices, feeding streams of wireless data to the home hospital; constantly regulating your bodily systems. How are they going to be powered?

Revolutionizing Prosthetics 2009 Team Delivers First DARPA Limb Prototype
An international team led by the Johns Hopkins University Applied Physics Laboratory (APL) in the US, has developed a prototype of the first fully integrated prosthetic arm that can be controlled naturally, including the provision of sensory feedback and allows for eight degrees of freedom. This is an order of magnitude beyond previous efforts, including the haptic arm of Claudia Mitchell.

Real-Time Feedback System for Skiers Opens Possibilities
The vLink Computer System approach to skiing is rather novel. It's a data collection sensor set that clips to the front of a pair of skis, and in real-time, monitor in real-time forward speed and lateral displacement data of the skis as the skier proceeds down a mountain.
