Using handheld devices for mobile interaction with displays in home environments

摘要

An increasing number of households are equipped with a large number of TV sets and more and more of them are large highresolution displays. Furthermore, we see the integration of web browsing and email functionalities in these devices, which are then often controlled via a wireless mouse and keyboard. The latter were rather designed for the usage on a desk, rather then by a person sitting on their sofa in a living room. Therefore, this paper investigates the usage of a PDA, as a replacement which can be used for controlling a remote cursor and for text input. The results of the experimental comparison of these input devices show, as expected, the superiority of mouse and keyboard (as the study participants were very experienced with them). Surprising results were the task completion time and usability satisfaction when using the mobile device. These results show the applicability of using a mobile device for controlling an application on a remote screen. Using a mobile device provides the advantages that every person can e.g. use their own mobile phone or that these devices can be used in multi-user scenarios.
