3. Phase 3 Inspecting UI improvements: Comparative Heuristic Evaluation, Eyegaze Analysis, Motion-sensor PUI Evaluation

This study focuses on what is mobile experience’s emotional attraction and aims to propose relative mobile design guideline. After measuring users’ emotion change before the use, in the user and after the use of mobile phone, several important emotional factors were proposed. Based on the emotionally attractive evaluation on 3 types of mobile phone in the experiment, emotionally attractive quality guidelines for mobile phone were finally presented.

1. Through ‘shop visiting’, ‘eyegaze analysis’ methods, factors of emotional evocation before using the mobile phone were extracted.
2. Through ‘heuristic evaluation’, ‘UT’ methods, factors of emotional evocation in using the mobile phone were extracted.
3. Through ‘pocket story’, ‘experience monologue’ methods, factors of emotional evocation after using the mobile phone were extracted.
4. Emotional attraction measurement and emotion evoking factors analysis based on the appearance and functions of 3 types of mobile phone.

This research carried out users’ usability evaluation regarding to drum washing machine’s control panel and PUI factors as well as investigated the real context of using the washing machine. Through ‘Home visiting’, ‘FGI’ methods, the interface relevant problems and factors for improvement were extracted. Finally, the user-centered innovative interface concept was proposed.

1. Study on the context of users’ usage of washing machine, such as using frequency, using procedure and using methods, in the real home environment.
   
2. Usability test focuses on comparative evaluation of learnability, error rate and efficiency between drum washing machine and others.
   
3. Practical interface concept design for control panel and PUI factors.

This research carried out synthetic analysis on various daily mobile activities of young generation who are good at managing mobile device and UCC (User Created Contents) and proposed in depth on products manufacture direction.
