Johnson and Nardi conducted a study to investigate the use of generic versus task-specific application software by people who create and maintain presentation slides. Zongker & Salesin discussed principles for creating animated presentations and proposed a script-based tool to actually create them. Some researchers also explored the tools and guidelines for creating electronic presentation slides. Cheng and Pulo use an infrared laser pointer to control presentation by use of hotspots and gestures. describe a paper interface for presentations using index cards, which was empirically evaluated in. Baudel and Beaudouin-Lafon used data gloves to capture hand gestures to control presentation.
Several people have explored technologies to support intuitive interaction techniques for electronic presentations. We hope our study result will guide the real design and implementation of future technologies, preventing usability problems from the beginning stage. Therefore, we conducted a Wizard of Oz user study. Instead of technological issues related to a specific working prototype, we are interested in people’s overall acceptance and preference of the techniques concepts, and the design issues related to them. In this paper, we explored two representative alternative designs of techniques to control electronic presentations: Bare Hand, where the presenter controls the presentation by touching the projection screen using hand and Laser Pointer, where the presenter controls the presentation by pointing to the projection screen with a laser pointer and clicking a button on it. But as far as our knowledge, little research has focused on the systematic evaluation of alternative interaction techniques specific to electronic presentations. Many people attempted to develop alternative technologies that could assist people to give presentations. While the scenario of giving presentations is completely different from single-user desktop applications, currently available presentation applications, are still relying on control mechanisms using keyboard and mouse, which highly restricted the interaction between the presenter and the audience. : User Interfaces - Evaluation/methodology, User-centered design Nowadays people are relying more and more on computers and slideshow presentation software to convey ideas to public.
