Abstract

A controller identifies, when a contact position of a finger is detected by a detector, an object on a screen of a display device designated by the contact made on an input surface, on the basis of the contact position detected by the detector. When the object on the screen is identified, the control unit selects the object as an object to be moved, according to pressing force detected by the detector. When the contact position detected by the detector moves, with the object on the screen kept selected as the object to be moved, the controller moves such object to be moved on the screen, according to the movement of the contact position.

First claim

What is claimed is:

1 . A user interface device that controls a display on a screen of a display device, according to a contact on an input surface, the user interface device comprising:
a detector configured to detect a contact position on the input surface and a pressing force applied to the input surface owing to the contact; and a controller configured to control a display on the screen according a detection result provided by the detector, wherein the controller is configured to:
identify, as a designated object, at least an object on the screen designated by the contact made on the input surface, on a basis of a detection result of the contact position provided by the detector;
select at least one designated object as an object to be moved, according to the pressing force detected by the detector; and
move, when the contact position moves, with the object to be moved kept selected, the object to be moved on the screen according to the movement of the contact position.

2 . The user interface device according to claim 1 ,
wherein the controller selects at least one designated object as the object to be moved, out of a plurality of the designated objects, according to the pressing force detected by the detector.

3 . The user interface device according to claim 2 ,
wherein the controller increases a number of the designated objects to be selected as the object to be moved out of the plurality of designated objects, with an increase in the pressing force detected by the detector.

4 . The user interface device according to claim 3 ,
wherein the controller expands, when a plurality of the designated objects overlap on the screen, a range of the designated objects to be selected as the object to be moved, from the designated object at a frontmost position toward the designated object at a rear position, with an increase in the pressing force detected by the detector.

5 . The user interface device according to claim 3 ,
wherein the controller expands, when a plurality of the designated objects are different in area, a range of the designated objects to be selected as the object to be moved, from the designated object smallest in area toward the designated object larger in area, with an increase in the pressing force detected by the detector.

6 . The user interface device according to claim 1 ,
wherein a plurality of selection criteria for selecting at least one designated object as the object to be moved are specified, and the controller is configured to:
repeatedly decide which of a plurality of conditions corresponding to the plurality of selection criteria the pressing force detected by the detector satisfies; and
select, when a number of times of deciding that one of the conditions is satisfied is larger than a first number of decisions, while the object to be moved is not selected, at least one designated object as the object to be moved, according to one of the selection criteria corresponding to the one condition.

7 . The user interface device according to claim 6 ,
wherein the controller is configured to:
count the number of decision-making times with respect to each of the plurality of conditions, while the object to be moved is not selected; and
reset, when the number of decision-making times counted with respect to one of the conditions is larger than a second number of decisions equal to or fewer than the first number of decisions, the number of decision-making times counted with respect to the remaining conditions to an initial value, or decrease a value of the number of decision-making times counted with respect to the remaining conditions.

8 . The user interface device according to claim 1 ,
wherein the controller deselects, when at least one designated object is selected as the object to be moved, the at least one designated object as the object to be moved, according to the pressing force detected by the detector.

9 . The user interface device according to claim 8 ,
wherein the controller deselects, when at least one designated object is selected as the object to be moved, the at least one designated object as the object to be moved, provided that the pressing force detected by the detector is below a predetermined threshold.

10 . The user interface device according to claim 1 ,
wherein the controller deselects, when at least one designated object is selected as the object to be moved, the at least one designated object as the object to be moved, in a case where the detector stops detecting the contact position.

11 . The user interface device according to claim 1 , further comprising a tactile presentation unit configured to present a tactile feeling on the input surface,
wherein the controller controls the tactile presentation unit, when at least one designated object is selected as the object to be moved, so as to present a continuous tactile feeling to notify that the object to be moved is selected.

12 . The user interface device according to claim 11 ,
wherein the controller controls the tactile presentation unit, when causing the tactile presentation unit to present the continuous tactile feeling, so as to change at least one of frequency and amplitude of oscillation transmitted as the tactile feeling, according to a number of the designated objects to be selected as the object to be moved.

13 . The user interface device according to claim 1 , further comprising a tactile presentation unit configured to present a tactile feeling on the input surface,
wherein the controller controls the tactile presentation unit, when at least one designated object is selected as the object to be moved, so as to present a temporary tactile feeling for notifying the selection.

14 . A user interface device that controls a display on a screen of a display device, according to a contact on an input surface, the user interface device comprising:
a detector configured to detect a contact position on the input surface and a pressing force applied to the input surface owing to the contact; and a controller configured to control a display on the screen according a detection result provided by the detector, wherein the controller is configured to:
move, when the contact position detected by the detection unit moves, at least part of the objects displayed on the screen according to the movement of the contact position; and
change, when moving the at least part of the objects, a relation between an operation stroke corresponding to a movement distance of the contact position on the screen and an object travel corresponding to a movement distance of the at least part of the objects, according to the pressing force detected by the detector.

15 . The user interface device according to claim 14 ,
wherein the controller increases the object travel with respect to a certain fixed operation stroke, with an increase in the pressing force detected by the detector.

16 . The user interface device according to claim 14 , further comprising a tactile presentation unit configured to present a tactile feeling on the input surface,
wherein the controller controls the tactile presentation unit so as to change the tactile feeling according to the relation between the operation stroke and the object travel.

17 . The user interface device according to claim 16 ,
wherein the controller controls the tactile presentation unit so as to change a frequency of click feeling repeatedly transmitted as the tactile feeling, according to the relation between the operation stroke and the object travel.
