[0060]

[0061] The vehicle input device according to the first embodiment is a device that acquires the content of an operation input by a driver and outputs a signal corresponding to the operation to an external vehicle-mounted terminal. The vehicle input device according to the first embodiment includes a steering wheel 10 and a controller 20 . In the following, reference will be made to Figure 1 to Figure 3 to describe the system configuration.

[0062] figure 1 is a diagram showing the physical configuration of the steering wheel 10 .

[0063] Reference numeral 11 denotes a portion held by both hands of the driver in normal driving operation (grip portion according to the present invention) and is a circular disc.

[0064] Reference numerals 12A and 12B denote touch sensors arranged on the surface of the grip portion. The touch sensor covers the steering wheel by wrapping the grip part and is divided into two parts, a part (12A) in contact with the right hand and a...

[0110] In a first embodiment, the filtering of sensor information is performed using a grip pattern. In contrast, the second embodiment is a mode in which filtering using a grip pattern is not performed, the reliability of sensor information is judged based on a change in sensor information, and when the reliability of sensor information is low, the operation is skipped The input is fetched.

[0111] The configuration of the vehicle input device according to the second embodiment is similar to that of the first embodiment except that the vehicle input device according to the second embodiment does not include the input extraction unit 23 and the grip pattern storage unit 22 .

[0112] will refer to Figure 7 Processing performed by the vehicle input device according to the second embodiment will be described. In the second embodiment, steps S11 and S13 are omitted. In addition, the processing of step S12 is similar to that in the first embodiment.

[0113] In the second embo...

[0120] The third embodiment is a mode in which, instead of performing filtering of sensor information using a grip pattern, the arrangement of the driver's fingers is estimated based on the sensor information and the fingers corresponding to fingers irrelevant to the input operation are filtered. area. Figure 14 is a diagram showing the configuration of the controller 20 according to the third embodiment. The configuration of the vehicle input device according to the third embodiment is similar to that of the first embodiment, except that the vehicle input device does not include the grip pattern storage unit 22 and the input extraction unit 23 is replaced with a finger extraction unit 23A.

[0121] The finger extraction unit 23A is a unit for estimating the arrangement of the driver's fingers based on sensor information acquired from the contact sensor 12 and extracting only an area matching a specific finger instead of performing filtering using a grip pattern. In the thir...

Abstract

A user interface apparatus comprises a grip portion which is gripped by an operator; a contact sensor which is arranged on a surface of the grip portion and which detects a contact position; a sensor information acquiring unit configured to acquire sensor information outputted from the contact sensor; and an input operation acquiring unit configured to acquire a difference between pieces of sensor information respectively acquired at different times and to determine that an input operation corresponding to a predetermined pattern has been performed when the difference conforms to the predetermined pattern.

Description

technical field [0001] The present invention relates to user interface devices for manual input operations. Background technique [0002] Various devices that enable occupants of vehicles to perform input operations with respect to in-vehicle devices have been proposed. [0003] Since a touch panel display currently popular as an input device is mainly arranged on a center console between a driver's seat and an occupant's seat, it is necessary to move hands a considerable distance to perform an operation. In other words, there is considerable room for improvement regarding the workload imposed on the driver when performing an input operation. [0004] Examples of devices that enable a driver to perform an input operation with a smaller workload include a device described in Patent Document 1. The device described in Patent Document 1 has a touch panel built into a spoke portion of a steering wheel, and by performing an operation on the touch panel, the driver can perform a...
