Investigation of Dual-Modal Information Presentation

To design computing interfaces enabling users to best receive information, the effects of multimodal information presentation on user task performance and acceptance must first be ascertained. Based upon human attention models and prior research findings, this paper investigates dual-modal information presentation designed to test users’ ability to receive information via auditory channel in addition to normal visual mode. By examining users’ task performance and the extent to which users will accept dual-modal information presentation, this investigation seeks to establish a theoretical foundation for the design of multi-modal interfaces to allow users to access rich multimedia information space in the future.
