Abstract

Touch-screen interfaces have become a widespread-input-device tendency for computer systems. In this context, many studies investigate how to improve general usability for touch-screen devices. These studies consider different interaction design features that improve the usability for touch sensitive surfaces, considering the low accuracy it presents, given obstacles such as the “fat finger problem”, low-perception of pointing mechanisms, difficulties in the selection of small objects, among others. This work aims at presenting the link-offset-scale touch interaction mechanism for improving the usability for touch-screen devices. The link-offset-scale mechanism makes use of web-application-structure meta-data (identifying links) to provide feedback information about the selection of links in touch interfaces, while the surface is touched by the user. The link-offset-scale mechanism’s primary goal is to reduce the number of errors that users commit while interacting with touch-screen devices in the Web.
