A Seamless Multi-Touch Interaction for Collocated Multi-Mobile System

Abstract

Collocated Multi-Mobile System allows users to combine mobile devices as a massive surface with multi-touch capabilities for collaborative activities. In this paper, a study was conducted to identify the performance of a seamless multi-touch interaction using multiple mobile devices. The system owned a server that used to unify touch-input from multiple mobile devices thus able to create large multi-touch surface. Trough user-centred approach, this study found that the seamless multi-touch interaction was effective and intuitive during interaction across multiple devices. There were less errors and less movements made by users while doing certain task using the seamless multi-touch interaction. Issues such as bezel and lack of gesture were considered and will be resolved in the future.
