developing and evaluating web multimodal interfaces - a case study with usability principles
In this paper we describe an approach to facilitate the design of Web multimodal interfaces aiming at improving the user experience and the user interface usability using speech recognition together with the usual graphical user interfaces. We present a proposal for usability evaluation based on the heuristic evaluation, which considers the multimodal principles identified during a case study. As a result of using the proposed approach in the case study and from literature review, we report our considerations for the design, development and improvement of the Web multimodal interfaces.
