Careless touch
Stanislaw Zabramski · 2011
This short paper is a work-in-progress report on an experimental, exploratory comparison and evaluation of three input methods (mouse, pen, and touch-input) in a line-tracing task. A method to compare the original shape and user-generated version is presented. Measurements of user efficiency and accuracy showed that participants replicating a particular shape using touch-input performed the worst in terms of accuracy but were the fastest in comparison to the remaining input methods. No effect of controlled visual feedback was observed. Additionally, subjective operational biases were observed that, together with input method and expected shape related issues, might strongly affect the results.
