Support Tool Using Positions of Contents for Voice/Gaze-controlled Browsers

In this paper, we propose a support tool termed Calamari to improve voice/gaze-controlled browsers by using information about the position of contents. It can quickly determine the positions of links, images, and tables in a Web page. Positions in a browser window are important for voice/gaze-controlled browsers to deal with user commands associated with directions, for example, select "upper one" and "left figure." By using positional information, developers can effectively improve these browsers to use commands along with directions. The proposed tool is implemented in a proxy server; hence, it does not depend on browsers and operating systems. Although it rewrites an HTML document, it does not change the Web page design. We describe two applications using the tool and demonstrate that it is useful for developers to enhance the voice/gaze-controlled browsers.
