[0091] Figure 5 is a block diagram showing a schematic configuration of the input device according to the first embodiment of the present invention. The input device has a touch sensor 11, a load detection unit 12, a tactile sensation providing unit 13, a display unit 14, and a control unit 15 for controlling all operations. The touch sensor 11 receives an input to the display unit 14 through a finger or the like, and may be of a known type such as a resistive film type, a capacitive type, an optical type, or the like. The load detection unit 12 detects a pressure load applied on the touch surface of the touch sensor 11, and the load detection unit 12 may include elements such as strain gauge sensors, piezoelectric elements, etc. that respond linearly to the load. The tactile sensation providing unit 13 vibrates the touch sensor 11, and may include, for example, a piezoelectric vibrator. The display unit 14 displays an input object of an input key such as a push button swit...

[0108] Figure 10 and Figure 11 shows an input device according to a second embodiment of the invention; Figure 10 is a block diagram schematically constructed, Figure 11 is the front view. The input device is mounted on, for example, a mobile terminal, such as Figure 10 As shown, the input device has a touch sensor 41 for receiving input, a display unit 43 for displaying information based on an input position on the touch sensor 41, a load detection unit 44 for detecting a pressure load on the touch sensor 41, a vibration A tactile sensation providing unit 45 of the touch sensor 41 and a control unit 46 for controlling overall operations.

[0109] Such as Figure 11 As shown, a plurality of input objects 41a, such as number keys, have been set, printed, attached, etc. on the touch sensor 41 . Therefore, in the input device according to the present embodiment, each of the input objects 41 a constitutes a touch surface. In order to prevent an erroneous input of press...

Abstract

An input apparatus has a touch sensor (11) for accepting input; a load detector (12) for detecting a press load against a touch surface of the touch sensor (11); a touch sensation exhibition unit (13) for vibrating the touch surface; and a controller (15) for controlling driving of the touch sensation exhibition unit (13) so as to exhibit a click sensation to an object that is pressing the touch surface (pressing object) when the press load detected by the load detector (12) fulfills a first criterion for exhibiting a touch sensation; wherein the controller (15), after the click sensation at a time of pressing has been exhibited and when the press load detected by the load detector (12) fulfills a second criterion lower than the first criterion, controls driving of the touch sensation exhibition unit (13) so as to exhibit a sensation of a release corresponding to the click sensation. As a result, when an operator operates the touch sensor, a touch sensation of a real click similar to when a push-button switch is operated is exhibited, allowing the operator to perform a consecutive input operation without feeling a sense of incongruity.

[0001] Cross References to Related Applications [0002] This application claims priority and benefits from Japanese Patent Application No. 2009-177079 filed on July 29, 2009, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an input device with a touch sensor and a control method of the input device. Background technique [0004] In recent years, input devices with touch sensors such as touch pads, touch switches, etc. TV, lighting equipment, industrial equipment (FA equipment), etc.) Input devices such as operation units, switches, etc. for input operations. [0005] Various types of touch sensors are known, such as resistive film type, capacitive type, optical type, and the like. However, any of these types of touch sensors receive touch input from a finger or stylus, and unlike push button switches, the touch sensors themselves do not physically move even when being touched. [0006] Since the...
