Electronic signature system and related light control method

Abstract

An electronic signature system includes an electromagnetic pen; a display for displaying an electronic document; an operation module coupled to the display for detecting a state of the electromagnetic pen, controlling the display content, and initiating or controlling a signature process related to the electronic document; a light-emitting module disposed at at least one edge of the display; and a control unit coupled to the operation module and the light-emitting module for dynamically adjusting the operation of the light-emitting module according to the state of the electromagnetic pen or the context of the signature process.

The operating module is also used to compare the signature of the electromagnetic pen with the pre-stored signature data. The control unit is also used to control the light-emitting module to display the fourth light effect or the fifth light effect based on the comparison result of the signature of the electromagnetic pen and the pre-stored signature data.

2. The electronic signature system as described in claim 1, wherein the state of the electromagnetic pen includes at least one of the following: the electromagnetic pen being in an idle state, the electromagnetic pen contacting the display, and the electromagnetic pen signing.

3. The electronic signature system as described in claim 2, wherein the control unit performs at least one of the following to dynamically adjust the operation of the light-emitting module according to the state of the electromagnetic pen: when the electromagnetic pen is in the idle state, controlling the light-emitting module to display the first light effect; when the electromagnetic pen touches the screen of the display, controlling the light-emitting module to display the second light effect; when the electromagnetic pen is signing, controlling the light-emitting module to display a third light effect; and when the electromagnetic pen is idle for a period of time after signing, controlling the light-emitting module to resume displaying the first light effect.

4. The electronic signature system as described in claim 3 further includes: a setting unit coupled to the control unit, used to set the light-emitting module to display the first to the fifth light effects, to change the display color of the light-emitting module, to display a slow fade-in / fade-out, to keep it on, to flash, or to change the brightness, and to set a signature frame range when the electromagnetic pen makes a signature.

5. A lighting control method for an electronic signature system, comprising the following steps: detecting a state of an electromagnetic pen, controlling a display to show an electronic document, and initiating or controlling a signature process related to the electronic document; and dynamically adjusting the operation of a light-emitting module based on the state of the electromagnetic pen or the context of the signature process, the light-emitting module being disposed at at least one edge of the display; wherein the context of the signature process includes at least one of no document display, displaying the electronic document, signature completion, and signature error; wherein the step of dynamically adjusting the operation of the light-emitting module based on the context of the signature process includes at least one of the following: when the signature process is in a no-document-display context, controlling the light-emitting module to display a first lighting effect; when the signature process is in a displaying-the-electronic-document context, controlling the light-emitting module to display a second lighting effect; when the signature process is in a signature completion context, controlling the light-emitting module to display a fourth lighting effect; and when the signature process is in a signature error context, controlling the light-emitting module to display a fifth lighting effect; wherein... The lighting control method further includes the following steps: storing a pre-stored signature data; comparing the signature of the electromagnetic pen with the pre-stored signature data; and controlling the light-emitting module to display the fourth lighting effect or the fifth lighting effect based on the comparison result of the signature of the electromagnetic pen with the pre-stored signature data.

6. The lighting control method as described in claim 5, wherein the state of the electromagnetic pen includes at least one of the following: the electromagnetic pen being in an idle state, the electromagnetic pen contacting a screen of the display, and the electromagnetic pen signing.

7. The lighting control method as described in claim 6, wherein the step of dynamically adjusting the operation of the light-emitting module according to the state of the electromagnetic pen includes at least one of the following: when the electromagnetic pen is in the idle state, controlling the light-emitting module to display the first lighting effect; when the electromagnetic pen touches the screen of the display, controlling the light-emitting module to display the second lighting effect; when the electromagnetic pen is signing, controlling the light-emitting module to display a third lighting effect; and when the electromagnetic pen is idle for a period of time after signing, controlling the light-emitting module to resume displaying the first lighting effect.

8. The lighting control method as described in claim 7 further includes setting the first to fifth lighting effects displayed by the light-emitting module, causing the light-emitting module to change the display color, display a slow fade-in / fade-out, flash, or change brightness, and setting a signature frame range when the electromagnetic pen makes a signature.
