Abstract: A peripheral device with an adaptive scroll wheel can be used to provide additional control of a host computing device. A variable force is used to change friction on the adaptive scroll wheel for different situations. Examples include stopping a scroll wheel at an end of a document, changing a number of ratchet steps based on a number of items on a list, and changing scroll profiles based on application, such as a scroll profile for document processing and a scroll profile for gaming.

Abstract: 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.

Abstract: 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.

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.
