[0103] 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 switc...

[0120] Figure 10 with 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 A tactile sensation providing unit 45 of the vibration touch sensor 41 and a control unit 46 for controlling overall operations.

[0121] 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 pres...

[0141] Incidentally, input devices used in mobile terminals, for example, are generally used for so-called repeated taps to continuously input the same input object when inputting phone numbers, messages, and the like. In this case, as Figure 17 As shown, if the touch sensor 11 vibrates in a predetermined vibration pattern not only at the time of pressing but also at the time of release, the predetermined standard load at the time of release to provide a tactile sensation must be appropriately set.

[0142] That is, when a person quickly performs continuous input, the next input usually starts before the pressing load returns to "0", and the maximum load at the time of pressing changes. At this time, in the case where the standard load at the time of pressing and the standard load at the time of release to provide the tactile sensation are set to be equal as described in the first embodiment, for example Figure 18 As shown, if the pressure load is pulled back to the standar...

Abstract

An input apparatus has a touch sensor (11) accepting input; a load detector (12) detecting a press load against a touch surface of the touch sensor (11); a touch sensation exhibition unit (13) vibrating the touch surface; and a controller (15) 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 criteria for exhibiting a touch sensation; wherein after exhibiting the click sensation at a time of pressing, the controller (15), when the press load detected by the load detector (12) fulfills criteria for exhibiting the touch sensation, controls driving of the touch sensation exhibition unit (13) so as to exhibit a sensation of a releasing corresponding to the click sensation that had been provided to the object that had been pressing the touch surface (the pressing object). 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefits from Japanese Patent Application No. 2009-177074 filed on July 29, 2009, the entire contents of which are incorporated herein 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. An input device such as an operation unit, a switch, etc. for performing an input operation such as a television, lighting equipment, industrial equipment (FA equipment)). [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, these touch sensors themselves do not physically move even when be...
