Proposed Interaction: Think Twister meets Tetris.
We are creating a collaborative, embodied geometry game. This game could provide children with a collaborative learning environment in which to explore geometric properties of shapes as well as properties of symmetry and spatial reasoning. We are also exploring possibility of creating a shareable memento/artifact of their game play.
Figure 1 – Initial Setup
For the scope of the current project, a pair of users will use their limbs to activate circles on an interactive mat (Figure 1). Users must always keep one limb on the center spot. From a geometric stand-point, this center point acts as a frame of reference for body movements (rotations, extensions, etc.). This is an intentional design constraint within the environment that allows for comparison of asynchronously created shapes. We intend for this point to guide their movements such that we believe they will more likely notice patterns and relationships.
Figure 2 – As the shape approaches towards the users, they are supposed to collaborate and create the shape before it hits the mat.
Users will coordinate their body positions to make composite shapes supplied by the system (Figure 2) paying special attention to the orientation of each component shape. A shape will be projected on the floor near the mat, moving slowly toward the mat. Users must create the shape before it reaches the mat (time runs out). For a shape to be recognized as successfully created, users must be touching all necessary points at the same time. The display will also include a small schematic of all the shapes completed so far. In Figure XXX, the triangle is the challenge shape (component), the image in the upper left represents shapes completed so far (composite). Users will also receive feedback on the mat regarding their touch positions.
The game will have different levels of difficulty that require users to use more limbs (easy: legs only, medium: legs and an arm, hard: both legs and both arms). All successfully created shapes will be overlaid to create a final image that users could take with them (Figure 3 below).
