Force Feedback Technology
Commonly used in video games
Utilizes motors to provide force
feedback
Recreate tactile experience Simulate explosions
Gun recoil
Steering
Controllers Sony Dual-Shock Controller
Flight sticks
Arcade games

Advanced Haptics Devices
SensAble Phantom
Can be used to simulate a
single touch point
Simulate pressure, feedback,
and temperature
Used for surgical training and
3D modeling
Novint Falcon
Allows for precise movement ina 3D environment
Simulates weighted objects
Potential for highly interactive
games with feedback

How do they work?
Objects are modeled in
3D
A corresponding
touch wireframe
model is also produced
for the object
The device responds tothe properties of the
wireframe's coordinates

Uses
Simulate surgical procedures Training exercises
Remote surgery
CAD and 3D modeling
Simulate touching foreignobjects in space Data from space probes
Education for a variety ofsubjects
Physics Astronomy
Geology

Haptics and Touch Screens
Finding its way into GPS
systems and cell phones
Uses a movable touch
screen in combination withpiezoelectric sensors
When the button is
pressed, feedback is
provided along with asound
Designed to reduce input
errors

Computer Access for the Blind
Force Feedback Mice canprovide information aboutthe screen
Let a user know whatobjects are selectable
From there, a narratorcan provide moredetail
Potentially home in on anobject
Has not caught on in themainstream

Force Feedback and User Interfaces
As mentioned earlier, useof haptic feedback canaid users
E
xample The Nintendo Wii uses a
wireless controllercombined with IR, andforce feedback
When a user hovers overa task, the controller,rumbles very slightly toindicate an option

Conclusion
Haptic Technology enables users to simulate touch
and utilize a new input as well as output technology
Currently a niche technology, but has the potential
to appear on more home PCs, especially with the
Novint Falcon
The technology emerged in 1993 but has been
making continuous advances in an immense varietyof fields
