Technology of TechnoWorks


Our signature technologies are non-contact line-of-sight measurement and non-contact gazing point detection.
Line-of-sight measurement and gazing point detechtion technologies have been the subject of research and development for a long time. Until now, the dominant method of measurement has been the "Contact method", which requires subjects to wear contact lenses, goggles, or other eyewear. Measurements that use the contact method must be made in unnatural environments that are isolated from the real world., and the data obtained from these measurements is often very unreliable. Also, the technology has not been very advanced, and there have been numerous limits on the testing environment and on who can be tested.

With all of the limitations, you might ask, "why haven't people switched to a non-contact method that allows them to measure line-of-sight in environments that are closer to those that exist in the real world?". The problem is that there is a large technologicaal disparity between the non-contact and contact methods. In the contact method, goggles and other equipment can be used to adjust light levels and block unwanted light, but in the in the non-contact method, those types of environmental adjustments are impossible, so measurements are susceptible to direct influence from the surrounding environment. In the non-contact method, the eyes are ssubject to external light, and a no-contact measureing instrument must deal with challenges such as pupil constriction, tears, and reflections from glasses. A non-contact measureing instrument can only be made into a viable product if it provides accurate measurements and overcomes all of the challenges listed above.

Do you think that it's ineevitable that there will be limitations on the type of subject, that adjustment must be made to the measurement environment, that calibrating the instrument before measurement will require a lot of time,and that only people with knowledge of line-of,sight detection will be able to configure the instrument ?
We believe that if a device can only be used by a limited number of specialists, it has not been designed with any consideration for the customer, For example, the first computers and automobles could only be operated by specialists, but these products evolved over time so that now they can be used by almost anyone. Line-of-sight measurement devices must also evolve in the same way. Our design philosophy is to make our products so that even someone who is not familiar whith line-of-sight detection can turn on the switch and start measureing.

We specialize in non-contact measurement technology. Because this technology does not require subjects to wear special equipment, it enables customers to measure line-of-sight and gazing point data in natural environments. In addition, because our technology has been developed in parallel with research and development of tools for people with severe disabilities, it can measure the eye movement of an individual regardless of their physical condition. In other words, there are no limits on the measurement environment or on who can be tested.

We have incorpotated all of the advantages of our technology into a new product, the TE-9101B Eye Behavior Interface Unit. The main features of this instrument are listex below.


Non-contact measurement can be performed under Natural conditions.
Because the TE-9101B Eye Behavior Interface Unit uses a non-contact measurement method, the subject doesn't need to wear any special equipment, and the subject's line of sight and Gazing point can be measured under natural condition that matches those of the real world. A subject's eye movements can be affected by his or her psychological condition. Eye movements express emotions such as uneasiness and fear clearly.
Because the TE-9101B Eye Behavior Interface Unit uses a non-contact method, its CCD ca,era can be hidden in a box so that the subject connot see it. This enables the operator to measure the line of sight and Gazing point of the subject while the subject is totally unaware that measurement is taking place.

Light, Compact, and Portable Design
The TE-9101B Eye Behavior Interface Unit takes up an area of just 182 * 257mm (7.2 * 10.1 in) and weight a mere 1.9kg (4.2lb). To install the TE-9101B on a desk, all you have to do it put a laptop on it and attach a camera to it. After that, you can start measureing immediately. This makes it easy to perform measurement with the instrument in different locations.

Fully-Automatic Device Configuration
Conventional electronic measureing instruments have been difficult to use for people who aren't trained specialists. However, because the TE-9101B Eye Behavior Interface Unit has fully-Automatic device configuration, anyone can perform line-of -sight and Gazing point measurement simply by connecting the instrument to a computer. This feature is especially useful for researchers who engaged in fields outside of engineering., such as psychology and medicine.
Please take a look at the front panel of the TE-9101B Eye Behavior Interface Unit. You will only see a single power switch. This is proof that once you turn on the power, the instrument will be easy to operate, just like a VCR or an ordinary electronic appliance.

Pre-Measurement Calibration time of only 30 Seconds
Because every pair of human eyes is different, calibration must be performed before an individual subject's eye movements can be measured. Conventionally, calibration has required a large amount of time and has been a troublesome bottleneck on the progress of research. However, the TE-9101B Eye Behavior Interface Unit can finish calibration after only 30 seconds.
Therefore, even in research where it is necessary to obtain data from a large number of subject, the time spent calibrating the instrument for each subject can be kept to a minimum.

Absolutely No limits on the Subject or the Measurement Environment
Conventional instruments imposedd extremely strict limitations on the measurement environment and the subject. However, as long as the eye is not exposed to the brightness level equivalent to that of direct sunlight., the TE-9101BB Eye Behavior Interface Unit places no limits on external light. Furthermore, the TE-9101B Eye Behavior Interface Unit, whose research and development has focused on use by the severely disabled. has overcome a host of challenges that are the result of differences between individual subjects, such as pupil dilation and constraction, glasses, contact lenses, tear and eye mucus secretion, and eye and eyelid twitching. Thanks to these breakthroughts, the TE-9101B Eye Behavior Interface Unit is complately free from measurement environment and subject limitations.

Developing original software applications for Research and Development is easy
All of processing for line-of-sight measurement and Gazing point detection takes place inside the TE-9101B Eye Behavior Interface Unit. Only the measured data is transferred to the connected computer. This means that the computer program just receives the data about where on the computer display the subject's gazing point (X and Y coordinates) and uses thaat data to perform the desired operation. A user who understands this procedur can easily develop oroginal research software applications. Creating a software application is simple. All the application has to do is receive the coordinate data from the TE-9101B Eye Behavior Interface Unit and use the the data to perform the desired operation. For example, an application can use the received data to analyze line-of-sight and gazing point data, to control peripheral device, or to use the eyes as a mouse-like input device. This means that the TE-9101B Eye Behavior Interface Unit can be used as a line-of-sight measurement device or as a computer input device. The user has the freedom to choose from a wide range of possibilities.
