Eye tracking technology measures the location and direction of the human eyeball and visualizes "unconscious or unaware" eye movements. In recent years, it has been introduced in the manufacturing industry, and is starting to be utilized for such as visual inspection mainly in the Japanese market. In this article, we will introduce the eye tracking solutions offered by Tobii Technology Co., Ltd., which boasts the No. 1 share of the global eye-tracking market, together with Mr. Sugita, Southeast Asia sales representative of the company.
Data-driven standardization of visual inspection Wearable eye-tracking devices easily measure line of sight
Although automation has been progressing at manufacturing sites in Thailand in recent years, there are certain products that cannot be handled by automatic inspection due to the characteristics of materials (easily reflecting light, uneven surfaces, etc.). Especially for products with strict safety quality standards, such as automotive parts, visual inspection by the human eye is important. Tobii Technology's eye-tracking solution can improve the education system and work efficiency by digitizing the "way of seeing" of visual inspection, which is difficult to standardize, and using it for training.

Digitize the techniques and skills of skilled workers and reflect them in the operation standards manual Scientific elucidation on the causes of variations in work by individuals
Visual inspection is a task that is particularly susceptible to individual skills, and succession of the skills of skilled workers has been a longstanding issue at manufacturing sites. Especially at manufacturing sites in Thailand, it is very difficult and time-consuming to train on-site staff on the sensory aspects of the work, even if there is an operation standards manual prepared by the head office. By visualizing and standardizing the detailed points of inspection (points to be watched, time, and order) that are not covered in the general operation standards manuals, it is possible to improve the on-site training system and increase work efficiency. Furthermore, the greatest strength of Tobii Technology is that it not only provides eye tracking devices, but also analyzes the eye tracking data and assists in how to utilize and improve it.
