In an office or laboratory, the informal communication that suddenly occurs in a face-to-face meeting sometimes takes the form of a heated discussion or important information sharing. Visual information, such as pictures and graphs, facilitates the fast and accurate communication of an intention between people. Therefore, visual information should be shown quickly in this situation so that the conversation is not interrupted. This paper presents HyperInfo, a system that allows various types of content to be presented simultaneously. HyperInfo consists of a high-resolution large display, touch interaction device, and smartphone as a controller, and its operation is intuitive. The purpose of HyperInfo is to facilitate communication that utilizes visual information. Moreover, in HyperInfo an HTML rendering engine is applied that allows various types of content to be shown.
We show that the advantages of a large high-resolution display are that some contents can be temporarily moved into a corner so that they do not overlap other contents and that contents can be expanded if necessary.
