Problems solved by technology

[0004] The biggest disadvantage of the prior art is that the stylus is generally equipped independently of the portable electronic device itself, and cannot be completely integrated with the portable electronic device, and is relatively easy to lose. Once lost or damaged, the handwriting input function cannot be completed.
In addition, due to the frequent friction between the touch screen and the stylus, it is easy to cause damage to the parts

Abstract

This invention discloses a kind of portable electronic device with hand-written input function. Light-spot was generated on background by certain illuminant; the moving track was caught by the digital camera and transformed to hand written script by digital signal processor and input to the portable device. No extra pen or screen was needed and it is convenient for operating and is efficient.

Description

【Technical field】 [0001] The invention relates to a portable electronic device, in particular to a portable electronic device with a handwriting input device. 【Background technique】 [0002] Handwriting input devices are gradually popularized on various portable electronic devices such as mobile phones and personal digital assistants (Personal Digital Assistant, referred to as PDA). The handwriting input function is completed in the form of combining with a pen. [0003] Representative products such as the NOKIA6108 mobile phone, in addition to the traditional keyboard input system, are also equipped with a handwriting input system on the mobile phone, which includes a special handwriting input touch screen, and is equipped with a special stylus independent of the mobile phone body. The stylus writes on the touch screen, and the digital signal processor senses the position of the tip of the stylus on the touch screen through the touch screen, and further senses the movement...
