Posture measurement and correction using inertia sensors are find in applications in rehabilitation as well as in human robot interaction systems. This paper presents two designs of arm posture mapping and replication system using inertia sensors and vibro tactile feedback device. The designs differ in the number of vibro tactile actuators and the vibration feedback pattern used. User performance in replicating armpostures when using the different systems were compared. Results show that using fewer vibro tactile actuators to provide feedback is feasible and that a more informative vibration feedback pattern could improve user response time in replicating reference arm postures.
