Human–Computer Interactions pose special demands on the motor system, especially regarding the virtual tool transformations underlying typical mouse movements. We investigated whether such virtual tool-transformed movements are similarly resistant to irrelevant variation of a target object as skilled natural movements are. Results show that such irrelevant information deteriorates performance in perceptual tasks, whereas movement parameters remain unaffected, suggesting that the control of virtual tools draws on the same mechanisms as natural actions do. The results are discussed in terms of their practical utility and recent findings investigating unskilled and transformed movements in the framework of the action/perception model and the integration of tools into the body schema.
