Users’ perceptions on what makes a good computer keyboard varies. Laptop computers are often equipped with low-profile keyboards for improved mobility, while desktop computers often are equipped with traditional high-profile keyboards with longer displacement ranges. This work set out to explore if the keyboard height profile influence text entry performance. A controlled experiment was set up with N = 15 participants. The results show that the low-profile keyboard yielded on average 12% faster text entry rates than the high-profile keyboards. No significant effects could be observed on error rates.
