Abstract: Techniques involving selective modification of keyboard presentation and functionality. A commanding mode is selectively activated on a virtual keyboard. Activating the commanding mode attributes commands to respective individual keys of the virtual keyboard. Also in response to the commanding mode, indicia suggestive of the command is presented on those individual keys to which the commands were attributed. The commands can be executed in an application in response to selection of the respective individual keys when in commanding mode.

Abstract: A wearable device includes one or more biometric sensors configured to determine biometric data of a wearer of the wearable device and a stress assessment tool. The stress assessment tool is configured to determine a periodic stress score, via a machine-learning model, based at least on the biometric data, visually present, via a display associated with the wearable device, a graphical user interface (GUI) including the periodic stress score, receive wearer feedback evaluating the accuracy of the periodic stress score, adjust the machine-learning model based on the wearer feedback, determine a reassessed periodic stress score, via the machine-learning model, and visually present, via the display, the reassessed periodic stress score in the GUI.

Abstract: Various embodiments related to assigning z-order to a plurality of user interface elements are disclosed. One disclosed embodiment provides a method of assigning a z-ordering to a user interface element displayed on a multi-user interactive display based upon an interaction state of the user interface element, the interaction state being dependent upon how a user interacts with the user interface element. The method comprises detecting a change in the interaction state of the user interface element. If the change is an initiation of a movement of the user interface element on the display, the user interface element is moved to a first predetermined position within the z-ordering. If the change is an initiation of a user interaction with content contained within the user interface element, the user interface element is moved to a second predetermined position within the z-ordering.
