Input device and digital pen thereof

Abstract

An input device includes a digital pad and a digital pen. When a color picking switch of the digital pen is pressed by the user, the color picking switch generates a color picking signal. The color picking signal is transmitted to the digital pad or a computer through a wireless transmission module of the digital pen. According to the color picking signal, a color pointed through the digital pen is picked.

Description

FIELD OF THE INVENTION[0001]The present invention relates to an input device, and more particularly to an input device with a digital pen.BACKGROUND OF THE INVENTION[0002]With the increasing development of science and technology, computer systems become essential electronic devices. Generally, a computer system comprises a host, a display screen and an input device. For example, the common input device includes a mouse or a keyboard. In addition, the cooperation of a digital pen and a graphics tablet provides the function of an input device. When the user holds the digital pen to write or draw on the graphics tablet, the writing content or the drawing content is sensed by the graphics tablet. Then, an input signal corresponding to the writing content or the drawing content is transmitted from the graphics tablet to the host. According to the input signal, the characters, symbols or drawings that written or drawn on the graphics tablet with the digital pen are shown on the display sc...

Benefits of technology

[0008]In accordance with an aspect of the present invention, a digital pen is provided. The digital pen includes a pen body, an electromagnetic circuit module, a color picking switch and a wireless transmission module. When the pen body is held by a user, the pen body is operable on the digital pad. The electromagnetic circuit module is disposed within the pen body. When the pen body is operated by the user, the electromagnetic circuit module issues an electromagnetic signal to the digital pad, and the digital pad or a computer in communication with the digital pad implements an input action according to the electromagnetic signal. At least a portion of the color picking switch is exposed outside the pen body. When the color picking switch is pressed by the user, a color picking signal is generated. The wireless transmission module disposed within the pen body and electrically connected with the color picking switch. The color picking signal is outputted through the wireless transmission module, and a color pointed through the digital pen is picked according to the color picking signal.

[0009]In accordance with another aspect of the present invention, an input device is provided. The input device includes a digital pad and a digital pen. The digital pad is in communication with a computer. The digital pen includes a pen body, an electromagnetic circuit module, a color picking switch and a wireless transmission module. When the pen body is held by a user, the pen body is operable on the digital pad. The electromagnetic circuit module is disposed within the pen body. When the pen body is operated by the user, the electromagnetic circuit module issues an electromagnetic signal to the digital pad, and the computer implements an input action according to the electromagnetic signal. At least a portion of the color picking switch is exposed outside the pen body. When the color picking switch is pressed by the user, a color picking signal is generated. The wireless transmission module is disposed within the pen body and electrically connected with the color picking switch. The color picking signal is transmitted to the digital pad or the computer through the wireless transmission module. After the color picking signal is acquired by the computer, a color shown on a screen image of the computer and pointed through the digital pen is picked according to the color picking signal.

[0010]In accordance with a further aspect of the present invention, an input device is provided. The input device includes a digital pad and a digital pen. A screen image is shown on the digital pad. The digital pen includes a pen body, an electromagnetic circuit module, a color picking switch and a wireless transmission module. When the pen body is held by a user, the pen body is operable on the digital pad. The electromagnetic circuit module is disposed within the pen body. When the pen body is operated by the user, the electromagnetic circuit module issues an electromagnetic signal to the digital pad, and the digital pad implements an input action according to the electromagnetic signal. At least a portion of the color picking switch is exposed outside the pen body. When the color picking switch is pressed by the user, a color picking signal is generated. The wireless transmission module is disposed within the pen body and electrically connected with the color picking switch. The color picking signal is transmitted to the digital pad through the wireless transmission module. After the color picking signal is acquired by the digital pad, a color shown on the screen image and pointed through the digital pen is picked according to the color picking signal.

Problems solved by technology

When the user intends to pick a color shown on the screen image, the user cannot directly operate the digital pen with a finger to achieve this purpose.

The digital pen and the graphics tablet are not user-friendly to the regular users such as computer graphics designer.
