Abstrakt: With the introduction of gestural input, many laptops are now being designed with larger touchpads in order to allow for the most accurate use of these features. Vendors have recommended surface input area sizes ranging from 60mm (w) x 45mm (h) to 105mm (w) x 65mm (h) and larger. However, as touchpads have continued to grow, it has been discovered that large touchpads can sometimes increase usability issues from unintended activation. From observing users over time we have noticed that people tend to focus input in the center area of the touchpad, regardless of touchpad dimensions. Therefore it is questionable whether continuing to increase the size of touchpads is necessary. To answer this question we have conducted a study using two touchpads with the same surface materials, one with the dimensions of 140mm (w) x 65mm (h) and one with the dimensions of 95mm (w) x 63mm (h). We found that increased touchpad size did not have a significant effect on the input area that people used for pointing or gestural input. Additionally, we discovered that size did not have a significant effect on performance.
