Digitization of line of eye sight! Tobii Technology's eye tracking technology for standardizing visual inspections and reviewing operation standards manual｜Defect Outflow Prevention/Equipment Maintenance

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.

▲Visual inspection by skilled personnel
Inspection time: 13 sec.

▲Visual inspection based on operation standards manual before improvement (unskilled workers before the lecture)
Inspection time: 34 sec.

▲Visual inspection based on operation standards manual after improvement (unskilled workers after lecture)
Inspection time: 21 sec.

＜Benefits of implementing eye tracking in visual inspection＞
✔Reduction of human variability by standardizing operations
✔ Reduction of training (education) timeby manualizing visual inspection
⇒Review of operation standards manual
✔ Objective evaluation of workers’ skills

Providing from analysis to improvement of line-of-sight data by utilizing our accumulated know-how

“Tobii Technology Japan has played a central role in expanding the use of eye tracking in the manufacturing industry. There are about 20 eye-tracking manufacturers in the world, but our strength is that we not only sell software and hardware, but can also offer proposals from data analysis to improvement, which no other company can do. In the Japanese market, we are seeing an increase in the number of installations at automobile manufacturers and automotive parts manufacturing sites, and we expect further demand in Southeast Asia, especially Thailand, where safety and high precision standards are on the rise," says Mr. Sugita of Tobii Technology.

Nippon Denkei's Japanese offices have already been selling this product, and in recent years, there is an increasing number of eye-tracking related inquiries have been receiving in Thailand. Currently, there is no demo devise available in Thailand at this time, but we are ready to arrange a demo test for interested customers, so please feel free to contact us for more information.
