Instrumented Activity Dice for Assessing Throwing Performance: A Pilot Study

Assessment tests are crucial but often viewed as tedious work by the participants and the experimentalists. Consequently, research has been done to integrate assessments into serious games and to automate observations using computer vision or wearable sensors. However, the use of camera generates privacy concerns. Moreover, the behavior of a person can change when the person feels being recorded or when the person has to wear sensors. Hence, we investigate a different methodology to assess the physical status of a person - by integrating sensors into a tangible toy commonly used by the participants - an activity dice that can be embedded in serious games. We demonstrate that with this instrumented activity dice, limitations of throwing performance of a person can be assessed purely based on the recording taken from the activity dice when the person throws the activity dice. We further demonstrate that variables extracted from the dice are similar to the variables extracted from a video.
