Examples of controllers used in esports. (A) Gamecube controller, a typical example of a console controller. (B) Mouse and keyboard, used for personal computer (PC) gaming. (C) Arcade-style stick, most often used for console gaming. (D) Smartphone, used for mobile gaming.

Magnetic resonance imaging (MRI) scanner room setup. Entire needle placement procedure performed inside of scanner room. Two physicians performed needle placement and one engineer controlled MRI scanner (via in-room console) and targeting and visualization application (via wireless keyboard and mouse). To ease visualization and planning, images were projected onto screen within scanner room.

Ophthalmic ultrasound units () consist of a console, a foot pedal, one or two types of probes, and a keyboard (usually but not always). The probes contain piezo-electric crystals, which convert electrical energy into ultrasonic soundwaves in the frequency range of 8–80 MHz. These waves are sent to the tissue being examined and some of the waves are reflected, as echoes, back to the probe. These echoes are converted into electrical signals, which are processed to measure and create an image of the tissue.

The experiment setup for insertion trials under computer-assisted navigation. The operator controls the Cartesian stage to steer the needle via an MRI-compatible keyboard under visual guidance. (a) Guidance lines are generated from FBG-based reconstructed needle shape. (b) A scene during the experiment. (c) A remote monitor panel functions as a control console to set up parameters and record data. In this phantom insertion study, needle shapes extracted from camera images are used as ground truths
