发明名称 Tactile timepiece
摘要 A tactilely readable timepiece with a clock device that keeps time. The display comprises a display area and at least one moveable portion within the display. The moveable portion is moveable with respect to the display to form at least one displayed character that is recognizable by touch by a user and has a tactilely sensible shape that is independent of a system of dots. An actuator operably associates the clock device of the moveable portion for displacing and positioning the moveable portion to form the displayed character depending on the current time kept by the clock device.
