Abstract

A method of connecting device adapted to an interactive whiteboard system and a host device thereof are provided. The host device has an interactive display device. The method includes the following steps. A scanning process is executed to receive a notification signal which is continuously broadcast by a first client device. A representative icon is obtained from an icon base, and the representative icon is set according to device information of the first client device in the notification signal, such that the representative icon is related to the first client device. The representative icon is displayed on the interactive display device, and then a broadcast termination signal is transmitted back to the first client device after the representative icon is displayed. After receiving the broadcast termination signal, the first client device stops broadcasting the notification signal.

Claims

1. A method of connecting device, adapted to an interactive whiteboard system, the interactive whiteboard system comprising a host device, the host device having an interactive display device, and the method of connecting device comprising:

executing a scanning process to receive a notification signal, and the notification signal being continuously broadcast by a first client device;

obtaining a representative icon from an icon base;

setting the representative icon according to device information of the first client device in the notification signal, such that the representative icon is related to the first client device;

displaying the representative icon on the interactive display device; and

after displaying the representative icon, transmitting a broadcast termination signal back to the first client device, and after receiving the broadcast termination signal, the first client device stops broadcasting the notification signal.

2. The method of connecting device according to claim 1, further comprising:

before executing the scanning process, generating a plurality of icons in order to establish the icon base, wherein the icons are not displayed on the interactive display device.

3. The method of connecting device according to claim 1, wherein the step of obtaining the representative icon from the icon base comprises:

selecting one of a plurality of icons from the icon base; and

executing a checking process for the selected icon, wherein the checking process comprises;

checking whether the selected icon is related to an arbitrary client device;

if the selected icon is not related to the arbitrary client device, checking whether the selected icon is related to a frame display area of the interactive display device; and

if the selected icon is not related to the frame display area, using the selected icon as the representative icon of the first client device.

4. The method of connecting device according to claim 3, wherein the checking process further comprises:

if the selected icon is already related to the arbitrary client device, confirming whether the arbitrary client device corresponding to the selected icon is the first client devices;

if the arbitrary client device is the first client device, re-executing the scanning process; and

if the arbitrary client device is not the first client device, selecting another one of the icons from the icon base for re-executing the checking process.

5. The method of connecting device according to claim 3, wherein the checking process further comprises:

if the selected icon is related to the frame display area, confirming whether the frame display area is in a connected state with the arbitrary client device;

if the frame display area is already in the connected state with the arbitrary client device, re-executing the scanning process; and

if the frame display area is not in the connected state with the arbitrary client device, selecting another one of the icons from the icon base for re-executing the checking process.

6. The method of connecting device according to claim 1, further comprising:

when receiving a disconnecting signal broadcast by the first client device, checking the icon base to confirm whether the representative icon related to the first client device is present; and

if the representative icon related to the first client device is present, reclaiming the representative icon to stop using the representative icon to represent the first client device, and not displaying the representative icon.

7. The method of connecting device according to claim 1, further comprising:

when the host device is disconnected from the interactive whiteboard system, transmitting a broadcast starting signal to the connected first client device, wherein after receiving the broadcast starting signal, the first client device broadcasts the notification signal.

8. A host device, adapted to an interactive whiteboard system, comprising:

a communication interface, executing a scanning process to receive a notification signal, and the notification signal being continuously broadcast by a first client device;

a processing unit, coupled to the communication interface, obtaining a representative icon form an icon base, and setting the representative icon according to device information of the first client device in the notification signal, such that the representative icon is related to the first client device; and

an interactive display device, coupled to the communication unit and the processing unit, and configured to display the representative icon,

wherein after displaying the representative icon, the processing unit transmits a broadcast termination signal back to the first client device via the communication interface, and after receiving the broadcast termination signal, the first client device stops broadcasting the notification signal.

9. The host device according to claim 8, wherein the processing unit generates a plurality of icons in order to establish the icon base, and the icons are not displayed on the interactive display device.

10. The host device according to claim 8, wherein when obtaining the representative icon from the icon base, the processing unit first selects one of a plurality of icons from the icon base and executes a checking process for the selected icon, and the checking process comprises:

the process unit checks whether the selected icon is related to an arbitrary client device,

if the selected icon is not related to the arbitrary client device, the processing unit checks whether the selected icon is related to a frame display area of the interactive display device, and

if the selected icon is not related to the frame display area, the processing unit uses the selected icon as the representative icon of the first client device.

11. The host device according to claim 10, wherein the checking process further comprises:

if the selected icon is already related to the arbitrary client device, the processing unit confirms whether the arbitrary client device corresponding to the selected icon is the first client devices,

if the arbitrary client device is the first client device, the processing unit re-executes the scanning process, and

if the arbitrary client device is not the first client device, the processing unit selects another one of the icons from the icon base for re-executing the checking process.

12. The host device according to claim 10, wherein the checking process further comprises:

if the selected icon is related to the frame display area, the processing unit confirms whether the frame display area is in a connected state with the arbitrary client device,

if the frame display area is already in the connected state with the arbitrary client device, the processing unit re-executes the scanning process; and

if the frame display area is not in the connected state with the arbitrary client device, the processing unit selects another one of the icons from the icon base for re-executing the checking process.

13. The host device according to claim 8, wherein when receiving a disconnecting signal broadcast by the first client device via the communication interface, the processing unit checks the icon base to confirm whether the representative icon related to the first client device is present, and

if the representative icon related to the first client device is present, the processing unit reclaims the representative icon to stop using the representative icon to represent the first client device, and does not display the representative icon on the interactive display device.

14. The host device according to claim 8, wherein when the host device is disconnected from the interactive whiteboard system, the processing unit transmits a broadcast starting signal to the connected first client device via the communication interface, and after receiving the broadcast starting signal, the first client device broadcasts the notification signal.
