( 제품위치 : 과학기자재전시실 > 분석장비 > 시선검출 및 안구운동해석 )
The "TE-9101B Eye Behavior Interface Unit" is basically a test device to detect
the characteristic eyeball points of a subject. The unit detects and outputs information
such as characteristic eyeball points, eye gazing point's coordinates (x,y) on the
computer screen, calibration data, and eyelid blinking.
It is applicable to an infinite possiblity of field for whatever idea the user has in mind,
and a system can be created according to the application such as a simple input interface
for a computer, a simple eyeball movement tester, or a characteristic eyeball point tester, etc.
An outstanding benefit of the TE-9101B is that it is a non-contact, non-invasive type device
allowing testing of the eyeball in a natural environment. All that is required is connecting
to a computer having an ordinary RS-232C communication port (or USB) as standard equipment.
This means the user can easily create an original system compatible with his own special
application and peripheral equipment.
Plotting of eye gazing point
Application of using for an input equipment of computer
1. Detects characteristic eyeball points with non-contact image processing.
2. No pain or unpleasant sensations, long-term use also okay.
3. High speed processing at detection speed of 16.6 msec/cycle (1/60th sec.)
4. Detection status output with video signal to NTSC standards.
5. High resolution of ±0.7°in horizontal vertical directions (in-house comparison).
6. Accurate detection even if eyeball moves within video frame.
7. Individual differences or sickness have virtually no effect on results.
8. Subject can wear glasses or contact lenses (some restrictions apply).
9. Compatible with any computer with standard RS-232C interface (or USB).
10. TE-9101B can be remotely controlled via RS-232C communication port (or USB).
11. Ideal development tool for new applications.
12. Applicable to a wide range of fields.
I. Research fields
1. Design research
Various research for instance is being done in designs such as for magazines
and posters. Researchers are for instance discovering how a person's sensations
and impressions change according to the color, tint, position and size of the
letter or picture, etc. By utilizing the TE-9101BB, researchers can check a person's
first eye target focus position and eyeball movement when looking at something.
This information lets researchers come up with the best possible design.
2. Psychological research
There is a strong connection between a person's eyeball movements and their
psychological state. Data can be obtained with the TE-9101B on a person's
psychological state by measuring eyeball movement and eyelid blinks that occur
due to environmental or psychological changes from viewing photos, pictures or
letters shown on a display.
3. Eyeball movement research
The TE-9101B basically measures a person's eye target focus position within
a space at the front or above the display screen. Accumulated data on eye target
focus position, plots, calculated movement speed and direction, and other
eyeball movement data can then be analyzed.
II. Medical & welfare fields
1. Systems for the seriously physically disabled
Systems can be easily built up so that persons with ALS or muscular dystrophy,
persons with spinal cords injured in accidents, or disabled limbs can operate devices
or carry out conversations. We designed and built the TE-9100 Nursing System for
Enhancing Patients' Self-Support to make this possible and invite you to check out
its potential benefits.
III. Factory automation fields
1. Harsh factory environments
Using computers in environments with a lot of smoke, dust or oil causes many breakdowns
and operating errors in the computer and its input devices such as keyboards and switches.
The TE-9100 however uses non-contact input devices so all components can be placed in
sealed spaces and shutoff from harsh factory environments. The user can easily operate
equipment or change settings just by blinking his eyes at the glass-covered display.
2. Hazardous areas
Workers normally have to wear protective clothing when working in areas subject to
radiation or high temperatures. However the thick protective layer of work clothes make
it difficult to press keys on control panels and damages the buttons when heavy gloves
make contact with the keyboard. The TE-9101B however is a non-contact device, allowing
the control panel to be isolated from the harsh factory environment. This system delivers
high reliability and also maintains worker safety.
IV. Computer fields
1. Computer input device
Our system can be used as a computer input device just like a mouse or keyboard.
However, since the display is some distance away from the user, even with high performance
resolution within 1 degree that our unit provides, the control within 1 dot that a mouse
can deliver is not possible. So to utilize our unit for computer input, control application
software must be provided to split up the display screen into dozens of small windows
(display keys) for selection by the user.
V. Automotive electronics fields
1. Operates vehicle electronic devices
Many traffic accidents occur when the driver shifts his gaze away from the windshield in
order to operate electronic equipment in the vehicle. The TE-9101B however detects the
driver's line-of-sight to provide both safety and convenience while inside the vehicle.
Our system during night-time driving for instance: can flash the sub-brites according to
the driver's line-of-sight, to quickly indicate curves or other road hazards, display
electronic equipment switches such as for the car stereo on a heads-up display on the
windshield, or show the view as seen from the back mirror, reducing the need for the driver
to shift his line-of-sight to an absolute minimum while driving.
The TE-9101B therefore improves both improved driving safety and convenience.
2. Serving as the "Driver's Eyes"
Our system is being used to acquire driver line-of-sight data in a commercial product already
on the market. Since our system captures actual images as seen by the driver and plots the eye
target position on the image, a CCD camera must be installed near the driver's eyes to acquire
the images. This means that a contact detection device such as goggles are necessary.
If the user develops these goggles, then the TE-9101B system can be used as is without changes.
Rival systems require securing the driver's head in a fixed position, in our TE-9101B on the
other hand, if the CCD camera is secured to move and turn along with the driver, then no problems
occur even if the driver moves or turns his head for instance to check safety.
VI. Electronic Amusements fields
1. Game machines
Currently visual effects acheived by 3D imaging technology, sound effects and vibrations
by 3D audio technology are bringing virtual reality to life around us. Compared to real life
however, the sensations of speed and distance, focus points, and visual points that our eyes
can take in by virtual reality are still extremely poor. In an auto race game for instance,
if you twist the steering wheel the display on the screen still appears in focus even though
you are supposedly moving at high speed and it doesn't appear like real life at all.
By detecting eye target points with the TE-9101B system however, the user's action, line-of-sight
and display appear much more realistic and allowing players to enjoy virtual reality that is much
closer to real life.
Just as with the game machines mentioned above, using the TE-9101B system simulation devices
such as flight simulators and drive simulators delivers the viewer a virtual reality much closer
to real life.
