Abstract
Recently, the number of devices using the sensor technology to improve various sports techniques has increased. However, there are only a few devices that would support the improvement of training skills in basketball. In the research involving the development of a skill support device for basketball, i t is important to improve the free throw skills to acquire a physical posture of set-form. Therefore, we have developed a device for reforming the set-form by using auditory biofeedback. The proposed device measures the shoulder angle in real time and informs the ideal physical posture by a sound based on measured angle. According to our study for testing the efficacy of the device, the intervention group obtained 20% higher success rate than the control group.
