Abstract

Certain embodiments include a computer-method includes searching for a receiver having an active first wireless communication protocol. When the receiver is detected, the mobile input device connects to the receiver, and when the receiver is not detected, the method includes searching for a host computer having an active second wireless communication protocol (e.g., Bluetooth®) after the receiver is not detected. The method further includes connecting the mobile input device to the host computer when the receiver is not detected and the active second type of wireless communication protocol is detected. The method then continues to search for the receiver while the mobile input device is connected to the host computer having the second wireless communication protocol, and automatically switches the wireless connection from the host computer having the second wireless communication protocol to the receiver when the first type of receiver is detected.

First claim

What is claimed is:

1. A computer-implemented method of establishing a wireless connection for a mobile input device, the method comprising:
searching for a receiver having an active first wireless communication protocol;
in response to the receiver being detected:
connecting the mobile input device to the receiver;
in response to the receiver not being detected:
searching for a host computer having an active second wireless communication protocol after the receiver is not detected, wherein the first wireless communication protocol is different than the second wireless communication protocol;
connecting the mobile input device to the host computer in response to:
the receiver not being detected; and
the active second wireless communication protocol being detected;
continuing to search for the receiver while the mobile input device is connected to the host computer having the second wireless communication protocol; and
automatically switching the wireless connection from the host computer having the second wireless communication protocol to the receiver in response to the receiver being detected.

2. The method of claim 1 wherein the continuing to search for the receiver while the mobile input device is connected to the host computer having the second wireless communication protocol occurs periodically at a time that is between 1 second to 10 seconds.

3. The method of claim 1 wherein the continuing to search for the receiver while the mobile input device is connected to the host computer having the second wireless communication protocol occurs each time after a user input is received by the mobile input device.

4. The method of claim 1 wherein the second wireless communication protocol includes at least one of:
a Bluetooth-based communication protocol;
an infra-red (IR)-based communication protocol; or
a ZigBee-based communication protocol.

5. The method of claim 1 further comprising:
receiving an input to power-on the mobile input device;
switching an operational mode of the mobile input device from a low-power sleep-mode to an active-mode in response to receiving the input; and
switching the operational mode from the active-mode to the low-power-sleep-mode in response to determining:
the receiver and the second wireless communication protocol is not detected;
no inputs are received on the mobile input device for a threshold time;
the connection to the receiver is lost and the second wireless communication protocol is not detected; or
the connection to the second wireless communication protocol is lost and the receiver is not detected.

6. The method of claim 5 wherein the threshold time is between 5 minutes and 30 minutes.

7. The method of claim 1 further comprising:
receiving a user input on the mobile input device when an operational mode of the mobile input device is a low-power sleep mode, wherein the user input corresponds to one or more human interface device (HID) commands;
in response to receiving the user input when the mobile input device is in the low-power sleep mode:
switching the operational mode from the lower-power sleep mode to an active mode; and
generating the one or more corresponding HID commands.

8. The method of claim 7 further comprising:
storing the user input in a data buffer;
retrieving the user input after the operational mode is switched from the low-power sleep mode to the active mode; and
using the retrieved user input for the generating the one or more HID commands.

9. The method of claim 1 further comprising:
providing a haptic feedback on the mobile input device in response to the mobile input device connecting with the receiver or the host computer having the second wireless communication protocol.

10. The method of claim 9 wherein the haptic feedback is a first type of haptic feedback when the mobile input device connects with the receiver, and wherein the haptic feedback is a second type of haptic feedback when the mobile input device connects with the host computer having the second wireless communication protocol.

11. The method of claim 1 wherein the receiver is pre-paired with the mobile input device.

12. The method of claim 1 wherein the mobile input device is a presenter.

13. A computer-implemented system for establishing a wireless connection with a mobile input device, the system comprising:
one or more processors; and
one or more non-transitory computer-readable storage mediums containing instructions configured to cause the one or more processors to perform operations including:
searching for a receiver having an active first wireless communication protocol;
in response to the receiver being detected:
connecting the mobile input device to the receiver;
in response to the receiver not being detected:
searching for a host computer having an active second wireless communication protocol after the receiver is not detected, wherein the first wireless communication protocol is different than the second wireless communication protocol;
connecting the mobile input device to the host computer in response to:
the receiver not being detected; and
the active second wireless communication protocol being detected;
continuing to search for the receiver while the mobile input device is connected to the host computer having the second wireless communication protocol; and
automatically switching the wireless connection from the host computer having the second wireless communication protocol to the receiver in response to the receiver being detected.

14. The system of claim 13 wherein the continuing to search for the receiver while the mobile input device is connected to the host computer having the second wireless communication protocol occurs each time after a user input is received by the mobile input device.

15. The system of claim 13 wherein the second wireless communication protocol includes at least one of:
a Bluetooth-based communication protocol;
an infra-red (IR)-based communication protocol; or
a ZigBee-based communication protocol.

16. The system of claim 13 wherein the one or more non-transitory computer-readable storage mediums further contain instructions configured to cause the one or more processors to perform operations including:
receiving an input to power-on the mobile input device;
switching an operational mode of the mobile input device from a low-power mode to an active mode in response to receiving the input; and
switching the operational mode from the active mode to the low-power mode in response to determining:
the receiver and the second wireless communication protocol is not detected;
no inputs are received on the mobile input device for a threshold time;
the connection to the receiver is lost and the second wireless communication protocol is not detected; or
the connection to the second wireless communication protocol is lost and the receiver is not detected.

17. A non-transitory computer-program product tangibly embodied in a machine-readable non-transitory storage medium that includes instructions configured to cause one or more processors to:
search for a receiver having an active first wireless communication protocol;
in response to the receiver being detected:
connect a mobile input device to the receiver;
in response to the receiver not being detected:
search for a host computer having an active second wireless communication protocol after the receiver is not detected, wherein the first wireless communication protocol is different than the second wireless communication protocol;
connect the mobile input device to
