Schau genau!

[go to overview]

Schau genau! (look closely!) is a video game that is controlled solely by eye movement. It uses a new generation of low-priced, low-sized eye trackers. The game started in 2013 as a practical teaching course at the University of Koblenz-Landau. Later, the technical system, control interface and hardware were optimised to pose an attractive exhibit at the 2015 State Garden Show in Landau.

Schau genau! started in summer 2013 as a practical teaching course by the former WeST members Tina Walber and Christoph Schaefer. Goal of the course was to develop a video game that could be controlled solely by the eye movements of the players. Besides being fun the game should only analyse the players’ eye movements in order to gather information about the pictures displayed in the computer screen.

The player controls a butterfly and his objective is to collect as many flowers as possible. In addition, the names of certain flowers are displayed now and then and the player has to select the picture showing this particular flower. Once the butterfly steers into one of the many spider webs, the game ends.

The game is controlled by the players' eve movements. For this, the system used a new generation of eye trackers that is smaller, yet technical advanced and has a lower price than previous eye trackers. User do not need to have any experience in controlling games by game pads, mouse or keyboard which opens up the game to a broad audience. All technical equipment is placed inside a case that has been individually constructed to represent traditional arcade game cases.  

Besucherinnen spielen Schau genau! auf der LandesgartenschauFrom April to October 2015, Schau genau! has been exhibited at the State Garden Show in Landau, Germany. Every day, visitors were attracted by the game and played it. Schau genau! not only demonstrates the technologies used and investigated by WeST, but contributes to research itself: Anonymously collected statistics provide insight into usability of different eye tracking concepts and by this help to improve future technology. The results are also used in the EU project MAMEN, where eye-trackers, EEGrecorders and bio-measurement sensors are used to help disabled people use computers.

Schau genau! is only one of many potential use cases of this technology. For example, similar concepts could be used in museums, where visitors would be able to interactively gather information without the need for complicated user interfaces. But also companies could use this technology to present their products, and shops would be able to let the customer experience their products in a novel and playful manner.
