User friendly podalic interface for light weighted wearable robot arm

We previously proposed a wearable robot arm named Assist Oriented Arm, that solved weight and safety problems of the existing wearable robot arms. The previous user interface of AOA was consisted of multi-button switches. However, the previous version did not satisfy the users due to its complexity of operations. To solve this problem, in this paper, we propose two types of new interface of AOA: using foot pose and using great toe operation. From the experimental results, the user interface using foot pose is better than the one using great toe in terms of their operability.
