Announcing the release of our internally developed GAP Gaze Analyzing Perimeter device.

“GAP” is a new device developed in-house. And includes new software with enhanced AI analysis algorithms. “GAP” will be released in early 2021.

■ GAP with an internally developed head-mounted display to be released in early 2021

The new head mounted display will be added to the GAP series of visual field measurement devices. Sales will begin in early 2021. The GAP series consists of two models. The precision visual field measurement device "GAP-screener *1”. Which released last year. And the new static quantitative visual field measurement device "GAP*2". Which is releasing in the upcoming launch.

The heart of the GAP system is the new internally developed head mounted display. This display has significantly improved in the eye tracking*3 frame rate*4. The GAP measures the condition and visibility of the retina. This is done by analyzing the eye movements of the person being examined. The improvement in performance made it possible to analyze minute eye movements. Thus, allowing the system to make a more detailed analysis of the vision system. Additionally, The GAP system includes our original visual evaluation AI and algorithms. Combining this with the new hardware, visual field test accuracy has been greatly improved. Other companies head mounted displays with eye tracking have less functionality. The common frame rate of their eye tracking systems is 60-70 fps*5. The new GAP head mounted display has an extremely high detection frame rate of 120fps or higher 6*.

The display inside the new GAP is an OLED display manufactured by SHARP CORPERATION. (Headquarter: Sakai city, Osaka / President & Chief Operating Officer: Katsuaki Nomura). It is driven by a specialized chipset which was co-developed for this product. This display has high performance specifications for accurate display expressions. Such as, contrast, color, and gradation. It is also more than seven times brighter than the display used in previous version of the GAP series. The entire head-mounted display weighs just 400 grams. This is an approximate 30% reduction compared to the previous version.

A patient might have a visual field abnormality due to glaucoma or other factors. They may not be able to see dark areas due to a lack of sensitivity to light recognition. So, during examinations the brightness of the display is gradually increased. From this, the progress of the disease can be determined by the level of brightness and age of the patient. As a result of the maximum brightness level increase in the newly developed GAP system. The measurement sensitivity of the system is on par with a standard large Visual Field Perimetry Test machine.

■ Realizing highly accurate vision inspections using AI Enhanced Analysis Capabilities and Functions

The new GAP system not only improves the head mounted display, but also the software. This new software is the brains behind the GAP system. It has an upgraded software and enhanced analysis algorithms. An improvement beyond the accuracy of eye tracking is the new AI based gaze analysis logic. This allows us to obtain a much higher quality in the digital data. Thus, achieving a greater level of detail than previously possible. The combined result of all these enhancements is that the testing time is cut by one third. The previous test in screening mode takes roughly three minuets for both eyes. The new screening mode test is about two minutes.

The new GAP will contribute to the diagnosis of ailments by collecting vital eye data. Practically in the visual field-testing areas. The aim of the new head mounted display is to contribute to early detection of diseases. Examples such as glaucoma and dementia. As well as research into effective treatment of such diseases.

■ Sales Launch Date

The finalization of the device and software is complete. The product has started mass production. The sales launch is scheduled for early 2021. We will let you know when the details are finalized.


The development of the new GAP series was done in collaboration with EMC Healthcare. The development of the display chipset was done in collaboration with Sharp and EMC Healthcare. EMC Healthcare is a consolidated subsidiary of FINDEX.
