Haptic Systems Flashcards
1
Q
What is the haptic system?
A
Touch (Tactile/Haptic) Sense.
2
Q
Where does feedback from the haptic system come from?
A
Tactile feedback from equipment (keyboard, steering wheel, brake, engine vibration)
3
Q
With the advent of advanced technologies, why is there more interest in tactile feedback?
A
- Virtual reality devices give tactile information
- “Fly or drive by wire” – disconnected from physical systems, have you lost that source of information? Can it be mimicked?
4
Q
What is the sensitivity measurement of pressure?
A
Pressure (meissner’s corp) (touch)most sensitive =< 50Hz , vibration; (Pacinian corp) (sense of texture)
5
Q
Describe the haptic system.
A
6
Q
What is he largest tolerable amount of pressure?
A
Unkown
7
Q
What is the threshold (smalles detectable) pressure for the haptic system?
A
Finger tips 0.05 to 1.1 erg
Example: Wing of a bee falling on year cheek from a distance of 1 centimeter.
