Biological Haptic Feedback

Kinesthetic

Gross Size

Shape

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


5/13

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


6/13

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


7/13

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
