Abstract
With development of multimedia technology, the telecommunication technology such as mobile phone and Internet has pervaded our life. In addition, advancement of virtual reality technologies can provide various force sensations to users. It is expected that further studies of interactive force telecommunication including force display would expand application fields of multimedia services. In this paper, we used force display devices, which are called as 'Haptic Interface'. Though a usual Haptic Interface is only used as the force display device, our laboratory realized a force-feeling telecommunication system by use of two Haptic Interfaces, whose control algorithm uses force and position control Hybrid control algorithm. By use of this system, teaching performances of a line, which can be realized transmitting force feeling from a teacher to a student, are examined under several experimental conditions. These results show interesting human cognition characteristics.
