Abstract

An electronic apparatus with a touch input system is provided. When a complete touch signal is detected, a sliding angle and a sliding track of the complete touch signal are calculated. A menu operation interface with arc-shaped arrangement is displayed in a touch display screen when the sliding angle of the complete touch signal exceeds a predetermined angle. And when an incomplete touch signal is detected, a sliding angle and a sliding track of the incomplete touching signal are calculated for displaying a part of the menu operation interface with arc-shaped arrangement in the touch display screen.

Claims

1. An electronic apparatus with a touch input system, comprising:

a touch display screen, displaying information of the electronic apparatus, and having a first display screen edge and a second display screen edge; and

a touch sensing device, connected to the touch display screen, and detecting and receiving a touch signal,

wherein when the touch sensing device detects a complete touch signal, the electronic apparatus calculates a sliding track and a sliding angle of the complete touch signal, and displays a menu operation interface with arc-shaped arrangement in the touch display screen when the sliding angle of the sliding track exceeds a predetermined angle, wherein the menu operation interface with arc-shaped arrangement comprises a plurality of sector functional options, wherein the complete touch signal refers to that the touch sensing device continually detects the touch signal, the touch signal slides from the first display screen edge to the second display screen edge and the touch signal is terminated, and

when the touch sensing device detects an incomplete touch signal, the electronic apparatus calculates the sliding track and the sliding angle, and displays a part of the menu operation interface with arc-shaped arrangement in the touch display screen, wherein the incomplete touch signal refers to that the touch sensing device continually detects the touch signal, the touch signal slides from the first display screen edge to the second display screen edge and the touch sensing device does not detect that the touch signal is terminated.

2. The electronic apparatus with the touch input system as claimed in claim 1, wherein when the sliding angle of the sliding track does not exceed the predetermined angle, the electronic apparatus calculates the sliding track and the sliding angle, and displays a part of the menu operation interface with arc-shaped arrangement in the touch display screen, and when the touch sensing device detects that the touch signal is terminated, the electronic apparatus executes one sector shaped functional option last displayed by the part of the menu operation interface with arc-shaped arrangement when the touch signal is terminated and a corresponding function instruction thereof, and closes the part of the menu operation interface with arc-shaped arrangement.

3. The electronic apparatus with the touch input system as claimed in claim 1, wherein the predetermined angle is 45 degrees.

4. The electronic apparatus with the touch input system as claimed in claim 1, wherein the touch sensing device presets a valid region and an invalid region used for detecting the touch signal in the touch display screen, and the touch signal slides clockwise or slides anticlockwise.

5. The electronic apparatus with the touch input system as claimed in claim 1, wherein when the touch sensing device detects another touch signal input from an opposite direction and detects that the touch signal is terminated, the menu operation interface with arc-shaped arrangement is closed.

6. The electronic apparatus with the touch input system as claimed in claim 1, wherein as the menu operation interface with arc-shaped arrangement is activated, when the touch sensing device detects a signal of another touch form outside the menu operation interface with arc-shaped arrangement, the menu operation interface with arc-shaped arrangement is closed.

7. The electronic apparatus with the touch input system as claimed in claim 1, wherein as the menu operation interface with arc-shaped arrangement is activated, when the touch sensing device detects a signal of another touch form in an invalid region, the menu operation interface with arc-shaped arrangement is closed.
