Dong Xing Bao, Xiao Ming Li, Yi Zhong Xin, Xiangshi Ren · Advanced materials research · 2011
In this paper, we designed two experiments that can be used to investigate: 1) whether pen-based input operation can be affected by tilt angle of tablet; 2) at which tilt angle of tablet can user do pen-based input operation with comfort, quickness, and accuracy. The experiments include pointing tasks (1-dimensional and 2-dimensional) based on Fitts’ law and stroking tasks (linear and circle) based on Steering law. Each task would be done under 5 kinds of tilt angle of tablet: 0, 15, 30, 45, and 60 degrees.
