Prolonged-sitting computer use has contributed to certain unhealthy symptoms such as visual impairment and musculoskeletal disorders. To help reduce the health risk and promote healthier computer use, researchers have devoted a lot of time and effort developing user-friendly computer stretch/ massage programs for prolonged-sitting computer users. However, computer users also expressed their concern on long-term adoption of the programs. Therefore, this study aimed to develop and bring a proposed 3D character from the virtual world (in computer break software) to the real world. This study designed, developed and actually produced a “tangible” 3D character with 3D printing technology, which could be touched, held, and interacted with real time. A microcontroller, consisting a central processing unit (CPU), was pre-programmed to adjust for the ON duration of red, yellow and green LEDs light color to sense computer users’ working status via ultrasonic sensor. A quantitative questionnaire survey was used to collect users’ evaluation along with a face-to-face interview to solicit in-depth feedback of user experience. The prototypes were tested with 10 volunteer undergraduate students followed by a series of modifications. The overall satisfaction reached a high score of 4.68 (based on a 5-point Likert scale). Generally they thought the Daniel was useful to alert user’s sitting duration in front of computer and they would be willing to recommend it to friends. Currently a more robust evaluation with more participants is under way. The next issue will be the impact of the created interactive device on users’ working efficiency and task performance.
