Abstract
The influence of different touch screen interface design features on user experience and operators’ task performance was investigated in the current study. Eight participants performed different tasks on a touchscreen monitor with varied interface settings while their performance was recorded and compared. Results demonstrated that an oversized desktop touchscreen monitor could generate negative impacts on users’ performance. Smaller icon size also decreased task performance by increasing total response time. In addition, icon color also influenced users’ performance. Results of the current study provide useful data for new approaches to design improvements which will enhance human performance and users’ experience.
