1. VR Course Presentation The Future of VR Input Technologies By Huang Ting-Hao 2005.6.1

2. Outline  Unencumbered Input  New Input Devices  Direct Connection  BMI: Brain Machine Interface A monkey can control a robot !? Subvocal Speech

3. Unencumbered Input  To reduce wires used to collect input from participant. 1.Elecromagnetic or Ultrasonic Devices 2.Opticial Tracking Method 3.Opticial Tracking + Computer Vision Algorithms

4. New Input Device  In the future, there may be input devices which can change their shape and center of mass to MIMIC their real world counter part.

5. Direct Connection  Originally it is developed for curing blindness and deafness.  One day we will be able to perceive virtual world directly in the brain.  One day it will be true. But how long will it take ?

6. THE END ?

7. BMI: Brain Machine Interface  The Famous Animation: Ghost In The Shell

8. A Monkey Can Can Controll A Robot !?

9. The Sensor  More than 100 micro metal pins are used to record the action pontential of the neurons.

10. How It Operates ?

11. Telepresence / Teleoperation

15. Subvocal Speech  NASA scientists have begun to computerize human, silent reading using nerve signals in the throat that control speech.

16. Subvocal Speech (cont.)  Scientists "trained" special software to recognize six words and 10 digits that the researchers repeated subvocally.  stop 、 go 、 left 、 right 、 alpha 、 omega 、 0~9  Initial word recognition results were an average of 92 percent accurate.

17. Subvocal Speech (cont.)  With this technology, one can: 1.Control a machine by subvocal commands 2.People in noisy conditions could use the system when privacy is needed, such as during telephone conversations on buses or trains 3.Free your mind and create one!

18. Subvocal Speech (cont.)  Trend Toward Unencumbered Input Device Scientists are testing new, "noncontact" sensors that can read muscle signals even through a layer of clothing.
