Design and comparison of acceleration methods for touchpad
As the resolution of a notebook display increases, the efficiency of a touchpad is becoming a more important issue. In particular, it is often observed that users scrape the pad repeatedly to reach the close button of a window. In this paper, we propose two new cursor control methods utilizing the contact-area information that is provided by most touchpads. We compared the new methods with the mouse acceleration that is the most common cursor control method. An evaluation study showed that the new methods required smaller number of scrapings and shorter distance of scraping on the touchpad while their efficiency is similar to that of the mouse acceleration. All participants preferred the new methods to the mouse acceleration. Keywords Touchpad, large display, cursor control ACM Classification Keywords H5.2 Information Interfaces and Presentation: User Interfaces - Input devices and strategies.
