BUILD-IT: a brick-based tool for direct interaction

BUILD-IT is a planning tool based on intuitive computer vision technology, supporting complex planning and configuration tasks. Based on real, tangible bricks as an interaction medium, it represents a new approach to Human Computer Interaction (HCI). It allows a group of people, seated around a table, to move virtual objects using a real brick as a interaction handler. Object manipulation and image display take place within the very same interaction space. Together with the image displayed on the table, a perspective view of the situation is projected on a vertical screen. The system offers all kinds of users access to state-of-the-art computing and visualisation, requiring little computer literacy. It offers a new way of interaction, facilitating team-based evaluation of alternative layouts.
