A surprising find that pure touch-based sense organisms like hydras and jellyfish are capable of detecting changes in light levels in localised areas, strongly suggests that sight developed as part of the touch sense - and that some form of sight sensor is ideal when proprioception is not workable.
Haptics is the study of the sense of touch. There are many parts to touch, and five different types of touch nerve in the nervous system. Here, we look at what goes into detecting texture, how the nerves work, and some initial attempts to interface with them for VR.
The stuff of numerous sci-fi films – the concept of with no more than a gesture, moving data wholesale from one computer to the next, has been made real, with a device not only functional in the lab, but already on its way to mass market commercial use, integrated in satellite and cable TV units.
MoCap - Motion Capture - for all its impressive abilities, has definite limitations in terms of sensory fidelity, the expense and bulk of the rig. Gesture control is cheap and captures every little movement, but easily overwhelmed. Is a hybrid system possible?
A potential concern has been found in the psychological implications of gesture control interfaces. When we design such things we must be aware of a power some gestures have, to alter the perceptions and memories of those who witness them.
AR based Medical imaging technologies really began to take off in the early 2000s. There are a growing range of holographic, projective, interactive gesture recognition tools available, which can really make training and diagnosis so much easier.
Haptics is the study of the sense of touch. Touch has many parts, but the most basic, the most fundamental of all, is that of pressure.
The art of prosthetics has moved forwards once more, and Claudia Mitchell, who lost her arm in a motorcycle accident and became the first woman to be fitted with a bionic arm has now become the first woman to be fitted with an artificial arm ? same arm ? that returns a sense of touch to her nervous system.
