Design och konstruktion av kaross till ögonstyrt arkadspel
Tobii Technology AB is a global leading company in eye tracking. The technology is a part of acomputer screen called an eye tracker. It enables computers to follow eye movement whichfurther make it possible to control the computer by only using your eyes.The mission was to develop an arcade game for eye controlled games that Tobii can use in theirmarketing or as a tool when doing researches about the interest in the technology amongst gamecompanies. The product realization involved designing an innovative, functional and futuristiccase which gathered the existing hardware and software to build the final prototype. In order toattract users it was important to focus on the visual expressions.Initially, the project started off with an information retrieval which contained interviews, fieldstudies, tests and literature studies. Thereafter, a brainstorming session was held to producedifferent concepts of the arcade game and a requirement specification was made. During theconstruction phase of the chosen concepts some tests were made to prove the functionality of thedifferent parts. Drawings were created in order to manufacture a prototype of the shell.One of the most important requirements was to position users with different heights,130 ? 200cm, in front of the eye tracker and at the distance of 50 ? 80 cm for a successful calibration of theeyes. It was also important to design a robust and easy-to-clean exterior that can handle roughtreatment caused by the user. The concept had to fulfill the required design expressions bright,playful and futuristic. A need that emerged during the tests was to create a visual head movementbox, which is a cube of approximately44x22x30 cm, in which the player must stay in order tokeep contact with the eye tracker.The project resulted in iBar, the world?s first prototype of an eye controlled arcade game with thedimensions70x142x246 cm. The body consists of two boxes of 19 mm MDF and a helmet of 1mmstainless steel. The helmet meets the requirement of positioning the player and the wish ofvisualizing the head movement box. The graphic design of an eye on the helmet communicatesthe revolutionary new technology and conveys the design expressions. The lower wooden box,which the user stands on, is strengthened with a structure of wooden ribs and contains acomputer and a lift. The lift is connected to the upper wooden box and it elevates and lowers thebox that contains the eye tracker and the helmet. The upper box can be opened from the front foreasy access when needed. This report presents further details, complete drawings and the finalprototype of the shell.
