Abstract
An electronic handwriting processing method, used to process handwriting written on a writing medium with temperature-dependent color ink, including following steps: provide a temperature varying element; apply said temperature varying element, so that it reaches temperature to make said temperature-dependent color ink to change from a first color to a second color; and contact said handwriting with said temperature varying element, to change its color from said first color to said second color, wherein, one of said first color and said second color is visible, while the other is transparent. An electronic handwriting processing device is also disclosed.
Claims9
An electronic handwriting processing method, used to process handwriting written on a writing medium with temperature-dependent color ink, including following steps:
- provide a temperature varying element;
- said temperature varying element including both a heating element and a cooling element;
- and a power control device, connected electrically between said power supply and said temperature varying element, wherein said power control device includes a switch and a function switching element provided by said switch or by a contact sensing element;
- apply said temperature varying element, so that it reaches temperature to make said temperature-dependent color ink to change from a first color to a second color;
- and
- contact said handwriting with said temperature varying element, to change color of said handwriting from said first color to said second color, wherein, one of said first color and said second color is visible, while the other is transparent.
An electronic handwriting processing device, said electronic handwriting processing device comprising:
- a power supply;
- a temperature varying element, connected electrically to said power supply, to use power provided by said power supply to change a temperature of said temperature varying element, said temperature varying element including both a heating element and a cooling element;
- and
- a power control device, connected electrically between said power supply and said temperature varying element, wherein said power control device includes a switch and a function switching element provided by said switch or by a contact sensing element.
