| Summary: | 碩士 === 國立政治大學 === 資訊科學學系 === 104 === Owing to the advances in technology, the way of people to learn exercise has been changing gradually. Learning by the multimedia resources, therefore, has become a new trend of exercise learning which substituted the videos for the traditional coach lessons. However, when people watch the videos to learn the motion, it’s not only difficult to observe the subtle change, but also lacks of the haptic feedback for motion adjustment. Thus, the learning efficiency and experience may be affected. Besides, keeping in the wrong posture could also lead to the permanent sport injury. According to the reasons mentioned above, we present a motion guidance gauntlet which could provide people who is doing exercise with the force feedback to guide their movement to the correct position.
The system has primarily been through three times design, modification and user studies. At first, we conduct a pilot study to find out the position where is the most sensitive to the pressure on the forearm. Then, we take the feeling of being pushed as the concept of feedback design and modify the construction of the device continuously until users could clearly receive the force feeling and judge the direction where device guide to.
16 participants are recruited for two stages of evaluation. The experiments are executed when participants are in the status of exercising. The scenario between these two stages are different. Participants test without learning process at the first stage of evaluation. At the second stage of evaluation, participants have training process before the test start. According to the result, the accuracy is 82.15% at the first stage of evaluation. While adding the learning process, the accuracy has improved to 99.07% at the second stage of evaluation. Moreover, we also analyze user feedback to find the potential problem and discuss the corresponding solution.
