# Tiger:Wearable Glasses for the 20-20-20 Rule to Alleviate Computer Vision Syndrome

## TL;DR

Tiger is a wearable glasses system that uses multi-sensory data to detect screen viewing and provides real-time feedback, helping users follow the 20-20-20 rule to reduce Computer Vision Syndrome symptoms.

## Contribution

The paper introduces a novel multi-sensory fusion approach and real-time feedback mechanism in wearable glasses to accurately detect screen viewing activities for health guidance.

## Key findings

- High detection accuracy across various screen types
- Robustness to different ambient lighting conditions
- Positive user perception of usefulness and acceptance

## Abstract

We propose Tiger, an eyewear system for helping users follow the 20-20-20 rule to alleviate the Computer Vision Syndrome symptoms. It monitors user's screen viewing activities and provides real-time feedback to help users follow the rule. For accurate screen viewing detection, we devise a light-weight multi-sensory fusion approach with three sensing modalities, color, IMU, and lidar. We also design the real-time feedback to effectively lead users to follow the rule. Our evaluation shows that Tiger accurately detects screen viewing events, and is robust to the differences in screen types, contents, and ambient light. Our user study shows positive perception of Tiger regarding its usefulness, acceptance, and real-time feedback.
