Abstract: In some embodiments, a configurable lighting device, connectors, controllers, and methods for layout detection are provided. The configurable lighting devices, suitably connected, form an assembly of configurable lighting devices that can be removably connected with one another and re-arranged. Connectors are provided that form mechanical and electrical connections between configurable lighting devices such that a flow of electricity and control signals may be propagated without the need for direct connection between every configurable lighting device and a controller. The controller or devices connected to the controller are configured to perform layout detection such that pleasing visualizations may be rendered across the assembly that are rendered using at least the detected layout. When the configuration of the configurable lighting devices changes, the layout detection is automatically updated.

Abstract: Examples relate to improving typing accuracy using a virtual keyboard. One example enables detection that a key of the virtual keyboard has been pressed and identification of a finger of a user used to press the key of the virtual keyboard. The key that was intended to be pressed may be determined based on the determined key, the finger of the user, and a mapping of finger placement and keys of the virtual keyboard. Functionality associated with pressing the intended key may be performed.
