要約(日本語): The purpose of this study is to present a method to operate with the lowest power consumption by using a new 2-degree of freedom (DOF) linear resonant actuator (LRA) which can guide the operator to a destination. The guidance of a direction can be indicated by using a kinesthetic illusion which detects the change of force. The variation of this force can be directly generated by an asymmetric acceleration from the proposed 2-DOF LRA. To this end, we propose a method of generating the input voltage of the 2-DOF LRA with an asymmetric acceleration. In addition, the optimal operating frequency for operating at the lowest power consumption is analyzed. Finally, the feasibility of the proposed method is verified through the finite element analysis (FEA) results and the numerical simulation.
