Abstract

An information processing apparatus includes: display means for displaying an image including an object; detection means, which is stacked on the display means, for detecting a contact with the display means; and control means for switching an operation mode of the display means based on a ratio of the area of the object displayed in the display means to the area of a region of the display means in which the contact is detected by the detection means.

Claims

1. An information processing apparatus comprising display means for displaying an image including an object;

detection means, which is stacked on the display means, for detecting a contact with the display means;

control means for switching an operation mode of the display means based on a ratio of an area of the object displayed in the display means to an area of a region of the display means in which the contact is detected by the detection means; and

wherein the object displayed on the display means can be directly operated by a user by performing upon a surface of the detection means a gesture operation of collecting the displayed object and moving the displayed object in accordance with the gesture operation and the operation mode selected by the control means.

2. The information processing apparatus according to claim 1,

wherein an operation of moving a contact object by a predetermined distance in a predetermined direction with the contact object being brought into contact with the display means is a trace operation,

wherein, as the operation modes, there are a first mode, in which the object brought into contact with a finger out of a plurality of objects displayed in the display means is moved along the trajectory of the finger according to the trace operation as a process for the trace operation, and a second mode, in which one or more of the plurality of objects displayed in the display means are moved to be collected along the trajectory of the finger according to the trace operation as a process for the trace operation, and

wherein the control means switches the operation mode to the first mode in a case where the ratio is equal to or greater than a predetermined value, and switches the operation mode to the second mode in a case where the ratio is smaller than the predetermined value.

3. The information processing apparatus according to claim 2, wherein the control means also controls the performance of a process corresponding to the switched mode of the first mode and the second mode.

4. The information processing apparatus according to claim 3, wherein the control means controls the performance of the process by using a result calculated by a physical engine in a case where switching to the second mode is performed.

5. The information processing apparatus according to claim 1, wherein the control means calculates the ratio by using an average value of areas of a plurality of target objects or a processed value thereof as the area of the object in a case where there are the plurality of target objects to be operated out of objects displayed in the display means.

6. The information processing apparatus according to claim 1, wherein the control means switches the operation mode to a first mode when the ratio is equal to or greater than a predetermined value, and the control means switches the operation mode to a second operation mode when the ratio is smaller than the predetermined value.

7. The information processing apparatus according to claim 6,

wherein in the first mode, a contact object providing the contact with the display means directly moves the displayed object by dragging after the contact object is brought into contact with the displayed object, and

wherein in the first mode, the contact object flips objects located on the touch panel in a direction along a trajectory corresponding to a motion of the contact object after the contact object is brought into contact with the display means.

8. The information processing apparatus according to claim 6, wherein when the control means switches the operation mode to the first mode, the displayed object is moved in direct correspondence to a movement of a contact object providing the contact after the contact object is brought into contact with the displayed object and while the contact object remains in contact with the display means, and when the control means switches the operation mode to the second mode, objects displayed in the display means, which come into contact or in close proximity with the contact object while the contact object engages in a trace operation in which the contact object moves while remaining in contact with the display means, are collected to be positioned along a trajectory of the moving contact object.

9. The information processing apparatus according to claim 6, wherein when the control means switches the operation mode to the first mode, the displayed object is moved in direct correspondence to a movement of a contact object providing the contact after the contact object is brought into contact with the displayed object and while the contact object remains in contact with the display means, and when the control means switches the operation mode to the second mode, the contact object engages in a trace operation in which the contact object moves while remaining in contact with the display means, the contact object colliding with the displayed object while engaged in the trace operation, and the displayed object is moved from a point of impact based on a trajectory of the moving contact object at the point of impact.

10. The information processing apparatus according to claim 9, wherein a plurality of objects are included in the image displayed by the display means, and in the second mode, the contact object collides with the plurality of objects while engaged in the trace operation, and the plurality of objects move from respective points of impact based on the trajectory of the moving contact object at the respective points of impact, and the plurality of objects further collide with each other.

11. The information processing apparatus according to claim 9, wherein in the second mode, after colliding with the contact object, the displayed object is moved at a speed corresponding to a contact speed at which the contact object is brought into contact with the display means.

12. The information processing apparatus according to claim 9, wherein in the second mode, after colliding with the contact object, the displayed object is moved at a speed corresponding to a detected vibration caused by the contact object being brought into contact with the display means.

13. The information processing apparatus according to claim 1, wherein the ratio is a value of 1.

14. The information processing apparatus according to claim 1, wherein the area of the object displayed in the display means corresponds to a size of the displayed object, and the area of the region of the display means in which the contact is detected corresponds to a size of a contact object that contacts the display means.

15. An information processing method of an information processing apparatus that includes a display means for displaying an image including an object and a detection means, which is stacked on the display means, for detecting a contact with the display means, the method comprising the step of:

allowing the information processing apparatus to switch an operation mode of the display means based on a ratio of an area of the object displayed in the display means to an area of a region of the display means in which a contact is detected by the detection means,

wherein the object displayed on the display means can be directly operated by a user by performing upon a surface of the detection means a gesture operation of collecting the displayed object and moving the displayed object in accordance with the gesture operation and the operation mode.

16. An information processing apparatus comprising:

a display unit configured to display an image including an object;

a detection unit, which is stacked on the display unit, and configured to detect a contact with the display unit; and

a control unit configured to switch an operation mode of the display unit based on a ratio of an area of the object displayed in the display unit to an area of a region of the display unit in which the contact is detected by the detection unit,

wherein the object displayed on the display unit can be directly operated by a user by performing upon a surface of the detection unit a gesture operation of collecting the displayed object and moving the displayed object in accordance with the gesture operation and the operation mode selected by the control unit.
