The YoYo: A Handheld Device Combining Elastic and Isotonic Input

: We present a new input device for controlling three-dimensional graphics applications: the YoYo. The device consists of three elastically connected rings in a row, which can be moved relative to each other. The center ring holds a tracking sensor and a few application programmable buttons. The left and the right ring are elastic six degree of freedom controllers. The device is designed for two-handed interaction and combines elastic force input and isotonic input in a single device. Compact size, symmetric shape, and the elastic properties result in a “soft” and responsive feel of the device. We have used the YoYo for navigation and manipulation in three-dimensional graphics applications in the area of data exploration and scientific visualization. An informal user study and user observations have shown that
