TOUCH SCREEN DEVICE FOR ALLOWING BLIND PEOPLE TO OPERATE OBJECTS DISPLAYED THEREON AND OBJECT OPERATING METHOD IN THE TOUCH SCREEN DEVICE
First Claim
1. A touch screen device comprising:
- a touch sensing unit generating key values corresponding to touched ‘
touch position'"'"'s of a virtual keyboard for controlling application software being executed, the number of touches and touch time and transmitting the key values to the application software when sensing touches of the virtual keyboard while the virtual keyboard is activated;
an object determination unit reading text information of a focused object using hooking mechanism when the application software is executed based on the key values received from the touch sensing unit and the object among objects included in the application software is focused; and
a speech synthesis unit converting the text information read by the object determination unit into speech data using a text-to-speech engine and outputting the speech data.
