LINE Analysis
This project is a UX redesign study of LINE, one of the most widely used messenger services in Japan and across East Asia. While the app offers a simple and functional user experience, there are areas where usability can be further improved.
To identify these opportunities, I conducted a heuristic evaluation, eye-flow analysis, and competitive review, leading to redesign proposals aimed at enhancing clarity, consistency, and overall user convenience.

Main Goal
Background
Analysis 01
Heuristic Evaluation
I created a heuristic evaluation standard tailored to LINE and
conducted evaluations with three users.
conducted evaluations with three users.
There is a need for consistent screens and efficient, intuitive information layout.
Analysis 02
Eye Tracking & Touch Flow Analysis
I analyzed visual attention and touch flow based on the user’s visit purpose and
predicted actions across all flows. Screens that caused unnecessary touches or disrupted visual flow
due to inconsistent hierarchy were identified and analyzed.

Improve with consistent layout, reduced touch flow, and clear information hierarchy..

Competitor Benchmarking
I analyzed competing apps (WhatsApp, KakaoTalk) to identify
each service’s strengths and weaknesses.

Learning
Improving an existing product while maintaining its usability is more complex than designing a new experience from scratch.
Core communication features should align with users’ established behavioural patterns and maintain familiar interaction patterns.
Overall UI consistency should be preserved, but key screens that drive conversion need a clear visual hierarchy to draw attention effectively.
