Sonic Feedback

Sonic Feedback is an audio signal in response to a given action by the user. It is a central form of interactivity in an immersive environment. Just as important as force feedback, is the perception that when two objects interact, the appropriate sound is heard. Whether it is the sound of a rubber ball impacting on a wall, or the scrape of nails on a blackboard. The sound of feet trudging through sand, or high heels on concrete.

Sonic feedback encompasses all of these, and makes the virtual environment feel that much more physical, if it is in-place. If it is lacking, it has the opposite effect, making the environment that much more unreal.

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.

Two-way Link Between Sound and Fear Perception
It has long been known that sound can affect our emotions. A good tune or a sound reminding us of a terrifying event, bring associated memories to mind, that bring emotional states with them. What was not realised until recently however, was that the emotional state you are in when you hear the sound, changes the sound you hear in the first place. This makes sound a surprisingly potent tool for immersion feedback.
