Dead Finger

Dead Finger is a name sometimes given to a process usually termed white finger. It is a known side effect of prolonged exposure to vibration, such as found in many haptic feedback systems. Despite its name, dead finger can occur to any body part exposed to vibration for a prolonged period of time.

The body part initially turns white on the onset of this condition. It is caused by a loss of blood flow by prolonged exposure to vibration, the same as experienced with heavy machinery, and despite the name, it can occur on any part of the body.

If exposure continues past the tissue bleaching, possible side effects include that body part turning numb, an increased sensitivity to cold, and finally, necrosis ? where the tissue literally starts to die off. Hence, dead finger, literally.

Finger Movement Patterns for Complex Tasks Anticipate the Position for Task after Next
The movement of the natural body when it comes to in depth, detailed tasks that require lots of little finger movements, is it seems, something which is defined as much by the tasks before and after the one the fingers are doing, as it is by the task the fingers are doing right now. This is a real problem when it comes to figuring out how to replicate natural-looking finger movements.

Ishikawa Komuro Lab's high-speed robot hand
In May 2009, the Ishikawa Komuro Lab in Japan, demonstrated the capabilities that robotic manipulation of objects had reached. They had created a three-finger robot arm, with tactile sensors on its fingers, with each finger capable of independent 180 x 180 x 360 motion. All three were connected to a high-speed machine vision camera.

Fluidhand is a product of the Orthopaedic University Hospital in Heidelberg, Germany. It is the first complete hand prosthesis in which each finger moves separately, without being a separate unit.

Information Theoretic Death
In the purely physical world, death is a straightforward thing: You are either alive, or you are not. When you add in the purely virtual, heavily interconnected worlds of cyberspace, that model changes drastically. When do you deem someone to be irredeemably dead, if part of their mind is active and self-modifying online?

Large Image Display: AWGate 5.0: Self-Assembing Logos
This is the entrance world for ActiveWorlds, which every newcomer to the various worlds sees when they come in. It is thus in their interest to make it as flashy and awe-inspiring as possible. Those trees are all around the outside of this small world, and if you look at them and then conclude that they are nothing more than an irregularly shaped rock retextured with a leaf pattern, masked, and then dropped on top of a bark textured flagpole, you would be dead on the money. That is precisely what those are.
