## Abstract

A coordinate measuring apparatus and a method of controlling the same are provided. The coordinate measuring apparatus includes a touch panel comprising a plurality of electrodes, a driver configured to generate a driving signal and to provide the driving signal to the touch panel, a receiver configured to receive from the touch panel a first receiving signal and a second receiving signal corresponding to a signal transmitted from a coordinate indicating apparatus, and a processor configured to identify a form of a user's grip on the coordinate indicating apparatus based on the first receiving signal, and identify an activation region and a deactivation region of the touch panel based on the identified form of the user's grip and the second receiving signal.

## Claims

### Claim 1

A coordinate measuring apparatus, comprising:
a touch panel comprising a plurality of electrodes;
a driver configured to generate a driving signal and to provide the driving signal to the touch panel;
a receiver configured to receive from the touch panel a first receiving signal and a second receiving signal corresponding to a signal transmitted from a coordinate indicating apparatus; and
a processor configured to:
identify a form of a user's grip on the coordinate indicating apparatus based on the first receiving signal; and
identify an activation region and a deactivation region of the touch panel based on the identified form of the user's grip and the second receiving signal.

### Claim 2 (depends on 1)

The coordinate measuring apparatus of claim 1, wherein the processor is configured to identify whether a hand gripping the coordinate indicating apparatus is a left hand or a right hand based on the form of the user's grip and the second receiving signal.

### Claim 3 (depends on 2)

The coordinate measuring apparatus of claim 2, wherein the processor is configured to:
based on the form of the user's grip being a right-handed grip, identifying a left side or an upper-left side of the touch panel with reference to a position corresponding to the second receiving signal as the activation region and a remaining region as the deactivation region, and
based on the form of the user's grip being a left-handed grip, identifying a right side or an upper-right side of the touch panel with reference to a position corresponding to the second receiving signal as the activation region and a remaining region as the deactivation region.

### Claim 4 (depends on 1)

The coordinate measuring apparatus of claim 1, wherein the processor is configured to provide a user interface (UI) for setting the form of the user's grip, and identify the form of the user's grip based on a user input regarding the UI.

### Claim 5 (depends on 1)

The coordinate measuring apparatus of claim 1, wherein the processor is configured to identify at least one of a touch signal and the second receiving signal in the activation region, and identify the second receiving signal in the deactivation region,
wherein the touch signal is different from the first receiving signal according to the form of the user's grip.

### Claim 6 (depends on 5)

The coordinate measuring apparatus of claim 5, wherein the processor is configured to, based on the touch signal being identified in the deactivation region, ignore the touch signal, and based on the second receiving signal being identified in the deactivation region, re-identify the activation region and the deactivation region.

### Claim 7 (depends on 1)

The coordinate measuring apparatus of claim 1, wherein the processor is configured to identify the activation region and the deactivation region of the touch panel based on a history of identification regarding the form of the user's grip and the second receiving signal.

### Claim 8

A method of controlling a coordinate measuring apparatus comprising a touch panel, comprising:
generating, by a driver, a driving signal and providing the driving signal to at least one of a plurality of electrodes of the touch panel;
receiving, by a receiver, a first receiving signal;
receiving, by the receiver, a second receiving signal, through at least one of the plurality of the electrodes, corresponding to a signal transmitted from a coordinate indicating apparatus;
identifying, by a processor, a form of a user's grip on the coordinate indicating apparatus based on the first receiving signal; and
identifying, by the processor, an activation region and a deactivation region of the touch panel based on the identified form of the user's grip and the second receiving signal.

### Claim 9 (depends on 8)
