    • A symbol selector comprising a storage unit which stores a symbol list including predetermined arrayed symbols; a manipulator unit for manipulating a pointing position of a virtual pointer which moves virtually over the symbol list stored in the storage unit; a sensor unit which detects acceleration per unit of time that is applied to the manipulator unit; a motion direction determination unit which determines a motion direction of the virtual pointer, based on a detection result from the sensor unit; a motion unit which moves the virtual pointer in units of symbols in the motion direction determined by the motion direction determination unit; and a selection unit which selects a symbol currently pointed to by the virtual pointer moved by the motion unit.
    • 一种符号选择器,包括存储单元,存储包括预定排列符号的符号列表; 操纵器单元,用于操纵虚拟指针的指向位置,虚拟指针位于存储单元中存储的符号列表上; 传感器单元,其检测施加到所述机械手单元的每单位时间的加速度; 运动方向确定单元,其基于来自所述传感器单元的检测结果来确定所述虚拟指针的运动方向; 运动单元,其以由运动方向确定单元确定的运动方向的符号为单位移动虚拟指针; 以及选择单元,其选择由运动单元移动的虚拟指针当前指向的符号。
