Comparison of 3 Eye-Tracking Devices | Ayumi Explains the Latest Prices, Subsidy Programs, and How to Choose in 2026

Various systems have been implemented to help individuals with speech impairments lead more comfortable lives.

In the past, written communication was commonly used, but recently, devices have been developed to facilitate easier communication.

Among these, eye-tracking devices, a type of assistive technology, allow individuals with difficulty expressing themselves to communicate, making them an important technology.

So, what kinds of eye-tracking devices are available?

This article introduces eye-tracking devices particularly recommended for individuals with disabilities, along with information on purchase prices and subsidy programs.

It is packed with essential information for those considering implementing eye-tracking devices, so please use it as a reference.

1. What is an Eye-Tracking Device?

An eye-tracking device is a tool that detects eye movements to operate computers or tablet devices.

Typically, operating a computer or tablet requires hand or finger movements.

However, individuals with disabilities may be unable to operate devices due to limited hand mobility. Thus, eye-tracking devices were developed to allow operation through eye movements instead of hands or fingers.

Eye-tracking devices are a type of communication aid, with "Talking Aid," released in 1985 and still ongoing, being a famous example.

Eye-tracking devices are gaining attention as more user-friendly communication aids.

There are various methods for detecting gaze with eye-tracking devices, with the use of infrared filters being a well-known approach.

This method extracts the center points of the pupil and corneal reflection from an image of the eye captured using infrared light, determining gaze from the relative position of these two points.

Other devices use blinks for operation, and the feel varies greatly depending on the type and method.

Eye-tracking devices can be broadly categorized into two types:

• Contact type worn on the body, like glasses
• Non-contact type attached to displays

Eye-tracking devices, as assistive technology, include the following software:

• For communication
• For training (educational)
• For measurement (research)

Since the feel and target age vary with each software, choose an eye-tracking device with the optimal software.

2. Prices and Subsidy Programs for Eye-Tracking Devices

Eye-tracking devices used to cost over a million yen, making them inaccessible for many.

Nowadays, with various technologies being applied to assistive devices, more affordable eye-tracking devices are available.

If you already have a computer or tablet, you can purchase an eye-tracking device for just a few tens of thousands of yen.

However, integrated eye-tracking devices that include a computer or tablet can cost over 200,000 yen.

To support the purchase of these expensive devices, subsidy programs are available to reduce the cost.

To apply for the subsidy program, the individual with a disability or their guardian must apply to the city or town mayor.

Based on the evaluation or opinion of a rehabilitation consultation center for the disabled, the mayor's decision will determine eligibility for the subsidy.

The user typically bears 10% of the cost, with the monthly maximum determined by household income.

Since the amount can vary based on the degree of disability and household income, please contact your local government for details.
