SH-Model and Its Application in Human Interface Design

We proposed a new model (SH-Model) to observe the human effects in pointing tasks.The SH-Model is approved as a reliable evaluation model.We also show how the SH-Model can be applied as an evaluation tool to observe the human effects.We evaluated four input devices, a mouse, a pen with a big tablet, a trackball and a pen with a small tablet.The comprehensive analysis including the SH-Model, ANOVA analysis and questionnaire can offer a clear comparison of the four input devices.The coefficients of the human factor in the SH-Model show the features of different human performance effects when using different devices.According to our analysis, the mouse is the best for the pointing task designed for our experiment, whereas the trackball is the worst.This study not only verifies the application of the SH-Model as a valid evaluation tool for the various devices, but also helps us to observe the human effects separately from the system effects.
