This is evident by the increasing market share of large-sized displays. The scope of this study is to investigate the usage of large displays for personal workstation. The primary purpose is two-fold: to understand the appropriate space requirements for editing and browsing related primary tasks; and to investigate the efficiency of pointing tasks at the peripheral region of a large display. The experimental results show that under a large display environment, instead to enlarge the window size to full screen, users prefer a window width of 19 cm-24 cm. When users browse web pages with more pictures, a wider window is preferred. The second part of this study compares clicking tasks on a flat and a curved display at peripheral region of different locations. The results suggest that Fitts’ Law holds for clicking tasks on a flat display in terms of target size and distance. For curved display, however, affected by the curvature level and the target location, a clicking task requires longer adjustment time when compared with the same task on a flat display. On the other hand, given the same target width, a clicking task located at further end of a display requires longer movement time on a flat display compared with curved display. In addition, when target located at further end of a large display, the perceived target width is less than real target width in accordance to the view angle, the experiment results suggest that perceived target width is a better predictor in Fitts’ Law with a R2 equals to 0.9519 for wrist.
