Method for controlling pointing device, pointing device and computer-readable storage medium
First Claim
1. A method for controlling a pointing device of a multi-touch type capable of sensing on/off states of a first input point and a second input point independently of each other, comprising:
- performing input mode control in such a manner that a one-point input mode is set as an initial state, the one-point input mode is changed to a two-point input mode when both the first input point and the second input point are turned on and the two-point input mode is changed back to the one-point input mode when both the first input point and the second input point are turned off; and
determining a coordinate position of an indicated point on the basis of an absolute position of the first input point in the one-point input mode and on the basis of a relative positional relationship between the first input point and the second input point in the two-point input mode.

Abstract
An input mode is controlled in such a manner that a one-point input mode is set as an initial state, the one-point input mode is changed to a two-point input mode when both the first input point and the second input point are turned on and the two-point input mode is changed back to the one-point input mode when both the first input point and the second input point are turned off. A coordinate position of an indicated point is determined on the basis of an absolute position of the first input point in the one-point input mode and on the basis of a relative positional relationship between the first input point and the second input point in the two-point input mode.

11. A method for controlling a pointing device of a multi-touch type capable of sensing on/off states of a plurality of input points independently of one another, comprising:
-
grouping the plurality of input points by setting an input point turned on first as a first input point of a first group, setting an input point turned on next within a predetermined range from the first input point of the first group as a second input point of the first group, setting an input point turned on next out of the predetermined range from the first input point of the first group as a first input point of a second group, setting an input point turned on next within the predetermined range from the first input point of the second group as a second input point of the second group and repeating the settings if necessary; performing, in each group, input mode control in such a manner that a one-point input mode is set as an initial state, the one-point input mode is changed to a two-point input mode when both the first input point and the second input point are turned on and the two-point input mode is changed back to the one-point input mode when both the first input point and the second input point are turned off; and determining, in each group, a coordinate position of an indicated point on the basis of an absolute position of the first input point in the one-point input mode and on the basis of a relative positional relationship between the first input point and the second input point in the two-point input mode. - View Dependent Claims (12, 13)

14. A pointing device of a multi-touch type capable of sensing on/off states of a first input point and a second input point independently of each other, comprising:
-
an input mode control portion that sets a one-point input mode as an initial state, changes the one-point input mode to a two-point input mode when both the first input point and the second input point are turned on and changes the two-point input mode back to the one-point input mode when both the first input point and the second input point are turned off; a one-point mode process portion that determines a coordinate position of an indicated point on the basis of an absolute position of the first input point in the one-point input mode; and a two-point mode process portion that determines the coordinate position of the indicated point on the basis of a relative positional relationship between the first input point and the second input point in the two-point input mode. - View Dependent Claims (15, 16, 17)

18. A pointing device of a multi-touch type capable of sensing on/off states of a plurality of input points independently of one another, comprising:
-
a group process portion that groups the plurality of input points by setting an input point turned on first as a first input point of a first group, setting an input point turned on next within a predetermined range from the first input point of the first group as a second input point of the first group, setting an input point turned on next out of the predetermined range from the first input point of the first group as a first input point of a second group, setting an input point turned on next within the predetermined range from the first input point of the second group as a second input point of the second group and repeating the settings if necessary; an input mode control portion, provided with respect to each group obtained by the group process portion, that sets a one-point input mode as an initial state, changes the one-point input mode to a two-point input mode when both the first input point and the second input point are turned on and changes the two-point input mode back to the one-point input mode when both the first input point and the second input point are turned off; a one-point mode process portion, provided with respect to each group obtained by the group process portion, that determines a coordinate position of an indicated point on the basis of an absolute position of the first input point in the one-point input mode; and a two-point mode process portion, provided with respect to each group obtained by the group process portion, that determines the coordinate position of the indicated point on the basis of a relative positional relationship between the first input point and the second input point in the two-point input mode. - View Dependent Claims (19)
