## Abstract

The system according to the embodiment comprises a recognition unit, an analysis unit, a provision unit, a detection unit, and a notification unit. The recognition unit analyzes eye movements and recognizes objects being viewed by the elderly person. The analysis unit analyzes information recognized by the recognition unit and generates voice guidance. The provision unit provides the voice guidance generated by the analysis unit. The detection unit detects abnormal movements or conditions of the elderly person using IoT sensor technology. The notification unit notifies designated contacts or medical institutions of abnormalities detected by the detection unit.

## Claims

### Claim 1

A system comprising: a recognition unit that analyzes eye movements and recognizes objects being viewed by an elderly person; an analysis unit that analyzes information recognized by the recognition unit and generates voice guidance; a provision unit that provides the voice guidance generated by the analysis unit; a detection unit that detects abnormal movements or conditions of the elderly person using IoT sensor technology; and a notification unit that notifies designated contacts or medical institutions of abnormalities detected by the detection unit.

### Claim 2 (depends on 1)

The system according to claim 1, wherein the recognition unit recognizes objects being viewed by the elderly person using eye-tracking technology.

### Claim 3 (depends on 1)

The system according to claim 1, wherein the analysis unit analyzes information recognized by the recognition unit and generates voice guidance.

### Claim 4 (depends on 1)

The system according to claim 1, wherein the provision unit provides the voice guidance generated by the analysis unit.

### Claim 5 (depends on 1)

The system according to claim 1, wherein the detection unit detects abnormal movements or conditions of the elderly person using IoT sensor technology.

### Claim 6 (depends on 1)

The system according to claim 1, wherein the notification unit notifies designated contacts or medical institutions of abnormalities detected by the detection unit.

### Claim 7 (depends on 2)

The system according to claim 2, wherein the recognition unit estimates the emotions of the elderly person and adjusts recognition accuracy based on the estimated emotions.

### Claim 8 (depends on 2)

The system according to claim 2, wherein the recognition unit analyzes not only eye movements but also facial expressions and head movements to improve recognition accuracy.
