Methods and systems for performing wireless communication are presented. In one example, a wireless peripheral device comprises a wireless transceiver configured to receive and transmit data over a primary channel, an optical sensor configured to receive data over an out-of-band channel, and one or more processors configured to: receive, via the wireless transceiver and over the primary channel, wireless signals including first key data from a second device; receive, via the optical sensor, optical signals including verification data from the second device; verify the first key data based on the verification data; and responsive to verifying the first key data based on the verification data, generate a digital security key based on the first key data, the digital security key used for following data transmission between the wireless peripheral device and the second device via the wireless transceiver.

Secure wireless communication with peripheral device

A method and system configured to receive a first report from a computer peripheral device by a receiver, determine that the first report is corrupted or received at a rate slower than the first report rate, compute a current trajectory of the computer peripheral device based on one or more intervals of movement data in the first report, compute a predicted trajectory of the computer peripheral device based on the first report, compute an incremental displacement of the computer peripheral device based on the predicted trajectory. The method and system can further generate data indicative of a position or displacement of the computer peripheral device based on the predicted trajectory of the computer peripheral device and send the data indicative of a position or displacement of the computer peripheral device at an interval that is less than twice a period of the first report rate to the host computing device.

Power efficiency based on a dynamic report rate

A method and system configured to receive a first report from a computer peripheral device, determine a trajectory of the computer peripheral device based on the first report, and determine a predicted activity level of the computer peripheral device based on the first report. The method and system can be further configured to compare the predicted activity level of the computer peripheral device with a baseline activity level and in response to determining that the predicted activity level of the computer peripheral device exceeds the baseline activity level, generate and send a first command to the computer peripheral device configured to cause the computer peripheral device to send a subsequent report of aggregated movement data at a first report rate.

Predictive peripheral locating to maintain target report rate

In some embodiments, a transceiver is configured to wirelessly transfer data between a host computing device and a plurality of peripheral devices over a communication path using a communication data construct sent by the transceiver comprising a plurality of packet structures forming a communication protocol for communicating peripheral device data (HID or audio data) between the host device and the plurality of peripheral devices. Each of the packet structures of the plurality of packet structures can include a single destination address configured to identify which of the plurality of peripheral devices will receive peripheral device data from the host computing device in the present packet structure and which of the plurality of computer peripheral devices will not receive peripheral device data from the host computing device in a present packet structure; and a data field configured to contain peripheral operational data for each of the plurality of peripheral devices.

Wireless communication protocol with peripheral devices

In some embodiments a transceiver is configured to wirelessly transfer data between a host computing device and one or more peripheral devices over a communication path using a communication data construct comprising a packet structure arranged in a repetitive communication structure. The repetitive communication structure can include a transmit time window within which the host transmits data to the one or more connected peripheral devices and a receive time window within which the host receives data from the one or more connected peripheral devices. A duration of the receive time window is set based on a predetermined communication report rate between the host computing device and the one or more connected peripheral devices. A new peripheral device is added as a connected peripheral device when the new peripheral device transmits a request to the host to be added as a connected peripheral device and the receive time window has time available to add the new peripheral device.

Wireless communication protocol having a predetermined report rate

A computer-implemented method includes sending a broadcast over a network requesting a response from other host computers on the network that are also communicatively paired with the input device, receiving a broadcasted response from a second host computer on the network indicating that it is communicatively paired with the input device, establishing a communicative connection with the second host computer via the network and automatically reestablishing the connection with the second host computer when the second host computer disconnects and reconnects to the network. In response to an edge-detect event, sending a control signal to switch the communicative pairing of the input device from the first host computer to the second host computer.

Automatic multi-host discovery in a flow-enabled system

Examples of techniques for wireless communication are presented. In some examples, an apparatus comprises a wireless transceiver and a hardware processor configured to perform: receiving, from a host device, a first indication of a host device clock signal, the apparatus and the host device being coupled via a wired interconnect; determining, based on the first indication and a second indication of an endpoint device clock signal, a phase relationship between the host device clock signal and the endpoint device clock signal; determining, based at least on the phase relationship, a first time for transmitting a sensor data request to a peripheral device of a computer; transmitting, using the wireless transceiver, the sensor data request to the peripheral device at the first time; receiving, from the peripheral device, the sensor data; and providing the sensor data to the host device via the wired interconnect as input data to the computer.

Wireless communication with peripheral device

A computer-implemented method includes detecting a first window being displayed on a display of a host computing device, detecting graphical content on the first window, generating a second window (overlay) on the display, wherein the overlay is configured on a window layer above the first window, and changing graphical qualities of the overlay based on the detected graphical content of the first window. The graphical qualities may include at least one of a shape, size, color, transparency, or opacity of the overlay. The method can further include receiving input data corresponding to a movement of a cursor on the first window, setting a transparency of an area around the cursor to a first transparency, and setting a transparency of a remainder of the overlay to a second transparency, such that the area around the cursor appears to highlight a corresponding area of the graphical content on the first window.

Modifying a highlighting function on a display based on content

Embodiments of the present invention provide a method and system of switching a wireless connection between a plurality of input devices and a first host device to at least a second host device. Embodiments of the invention are directed to systems and methods for switching multiple, independently connected data input devices from a first host computing device to a second host computing device together based on a single command or operation.

Input device with multi-host switching

In some embodiments, a computer-implemented method includes detecting, by a first software application, a first window being displayed on a display of a host computing device, where the first window displays graphical content and is generated by a second software application. The method can further include capturing an image of the graphical content on the first window and generating a second window on the display of the host computing device, where the second window is configured as a top-most window on the display, such that subsequent application-level and system-level window pop-ups occur on a window layer below the second window. The method can further include displaying the captured image of the graphical content on the second window.

Uninterruptable overlay on a display

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&#xae;) 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.
