  • SmartPTA: A Smartphone-Based Human Motion Evaluation System by Geonho Cha, Joonsig Gong, and Songhwai Oh
    • Abstract: This paper considers a human motion evaluation system (HMES) using two smartphones and a server. An HMES user wears retro-reflective markers on her 13 joints and follows a motion demonstrated by an expert. Two smartphones detect markers and transmit detected 2D marker positions to the server which reconstructs 3D motion of the user. The server performs a spatio-temporal alignment between the motion of the user and the motion demonstrated by an expert to evaluate the quality of the user’s motion. The proposed system is applicable for physical therapy and sports education as an inexpensive alternative. We demonstrate that the 3D motion of the HMES user can be reconstructed reliably in real-time and successfully aligned with the reference motion of an expert, providing real-time feedback to the user.
  • Smartphone-Controlled Telerobotic Systems by Hyemin Ahn, Hyunjun Kim, Yoonseon Oh, and Songhwai Oh
    • Abstract: This paper proposes a telerobotic system based on a smartphone and Nao, a humanoid robot from Aldebaran Robotics. A user can control the robot using her smartphone and interact with people and surroundings around the robot in a remote location. The overall system includes two servers to facilitate the connection between the user’s smartphone and the robot. We have particularly focused on providing a user-friendly interface such that a user who is unfamiliar with the robot platform can control the robot intuitively. Users of the system reported that they felt that they were aboard the robot platform and they were able to understand the surroundings of the robot easily using the developed smartphone application.
