A Context-Aware Collaborative Presentation System for Handhelds

Many systems support sharing and co-edition of slides, and thus enable active engagement and collaborative interaction among users of portable devices during lectures or meetings. The majority of these systems, however, run only on larger and more resource-full devices, like notebooks or tablet PCs. Handhelds, such as pocket PCs and smart phones, are becoming cheaper, lighter and with increasing computational power and storage capacity. Therefore, these devices are now also equally eligible for adoption in interactive classes, in the same way as notebooks and tablet PCs are used. In this paper, we present a collaborative presentation system named interactive presenter for handhelds (iPH) which supports sharing and co-edition of slide presentations, and which runs on both tablet PCs and handhelds. We also report the findings of performance tests and usability experiments with iPH on handhelds in an exercise class.
