Abstract

An information terminal device includes a displaying unit that displays information, a detecting unit that detects, when contact is made with a displayed screen of the displaying unit, a contact position and contact pressure, and a processor. The processor executes a process including storing, in a storing unit, a contact state indicating whether the contact pressure detected by the detecting unit is equal to or greater than a predetermined threshold, and controlling displaying on the displaying unit in accordance with the contact position detected by the detecting unit and the contact state that is stored in the storing unit.

Claims

1. An information terminal device comprising:

a displaying unit that displays information;

a detecting unit that detects, when contact is made with a displayed screen of the displaying unit, a contact position and contact pressure; and

a processor, wherein the processor executes a process comprising;

storing, in a storing unit, a contact state indicating whether the contact pressure detected by the detecting unit is equal to or greater than a predetermined threshold; and

controlling displaying on the displaying unit in accordance with the contact position detected by the detecting unit and the contact state that is stored in the storing unit.

2. The information terminal device according to claim 1, wherein, the controlling includes controlling the displaying such that, when the displayed screen of the displaying unit is switched, the contact state that is stored in the storing unit is maintained on displayed screen after being switched.

3. The information terminal device according to claim 1, wherein the storing includes:

determining that a first touch is detected, when the contact pressure detected by the detecting unit is equal to or greater than a first threshold and is less than a second threshold, and determining that a second touch is detected, when the contact pressure is equal to or greater than the second threshold; and

storing, in the storing unit, a contact state indicating that a contact with respect to the displayed screen continues, when it is determined that the first touch is detected.

4. The information terminal device according to claim 1, wherein the storing includes storing, in the storing unit, a contact state indicating that a contact with respect to the displayed screen does not occur, when the contact pressure is not detected by the detecting unit or when the contact pressure detected by the detecting unit is less than a first threshold.

5. The information terminal device according to claim 2, wherein the controlling includes controlling the displaying such that, when the contact state stored in the storing unit indicates that the contact pressure is equal to or greater than the predetermined threshold, an area associated with the contact position is displayed, on the displayed screen after being switched, in a manner distinguishable from a surrounding area.

6. The information terminal device according to claim 1, wherein the detecting unit includes

a touch panel that detects the contact position, and

a pressure sensor that detects the contact pressure.

7. A display control method comprising:

displaying information on a screen;

detecting, when contact is made with the displayed screen, a contact position and contact pressure;

storing a contact state indicating whether the detected contact pressure is equal to or greater than a predetermined threshold; and

controlling displaying on the displayed screen in accordance with the detected contact position and the stored contact state.

8. A computer readable storage medium having stored therein a display control program causing a computer to execute a process comprising:

displaying information on a screen;

detecting, when contact is made with the displayed screen, a contact position and contact pressure;

storing a contact state indicating whether the detected contact pressure is equal to or greater than a predetermined threshold; and

controlling displaying on the displayed screen in accordance with the detected contact position and the stored contact state.
