A method of operating an electronic gaming machine includes displaying a moving object to a viewer on a display screen of the electronic gaming machine, detecting and tracking eye movement of the viewer in relation to the moving object over a predetermined time period, comparing the eye movement of the viewer in relation to the object over the predetermined time period to a displayed position of the object over the predetermined time period, and determining based on the comparison that the eye of the viewer in relation to the moving object is tracking the object. Related systems and devices are disclosed.

A method for sharing gameplay is provided, including the following operations: executing a video game; while executing the video game, buffering a portion of gameplay of the video game, wherein buffering the portion of gameplay captures a predefined amount of gameplay prior to a currently executing gameplay; receiving an input generated from a controller device; responsive to receiving the input, then sharing the portion of gameplay to a website.

A hand held controller for a games console comprising an outer case and at least one control located on the controller. The controller is shaped to be held in at least one hand of a user such that the at least one control is operable by the user. The at least one control extends through an aperture provided in the outer case, and wherein the controller comprises a removable buffer mounted within the aperture.

Technologies are described for providing turning in virtual reality environments. For example, some implementations use roll turning that involves rotating around an outer edge of a control input, some implementations use tap turning to move directly to a location indicated by a control movement, and some implementations involve combinations of roll turning and tap turning.

A game controller includes a trigger-activation sensor, a sensor-activation feature, and a trigger-retention feature. The sensor-activation feature is moveable relative to the trigger-activation sensor. The trigger-activation sensor outputs a control signal based on a relative position of the sensor-activation feature and the trigger-activation sensor. The trigger-retention feature is configured to removably affix a selected removable trigger accessory to the game controller. The selected removable trigger accessory is one of a plurality of differently configured removable trigger accessories removably affixable to the game controller. The selected removable trigger accessory is configured to change the relative position of the sensor-activation feature and the trigger-activation sensor based on finger manipulation of the selected removable trigger accessory when the selected removable trigger accessory is removably affixed to the game controller.

A method for sharing gameplay is provided, including: executing a video game; while executing the video game, buffering a first portion of gameplay of the video game, wherein buffering the first portion of gameplay captures a predefined amount of gameplay prior to a currently executing gameplay; receiving a first input generated from a controller device; responsive to receiving the first input, then capturing a second portion of the gameplay of the video game that is continuous with the first portion of gameplay; receiving a second input generated from the controller device; responsive to receiving the second input, then enabling sharing of the first and second portions of gameplay to a website.

Examples are disclosed that relate to computing devices and methods for transforming output of a control stick. In one example, a method comprises: receiving a dead zone inflection point defining a boundary of a dead zone region and a playspace region within a first normalized unit-area movement space of the control stick, mapping the first normalized unit-area movement space to a second normalized unit-area movement space, using a scaling function comprising the dead zone inflection point, scaling each axis of the second normalized unit-area movement space to generate a scaled second normalized unit-area movement space, transforming the scaled second normalized unit-area movement space to a scaled first normalized unit-area movement space, receiving position data representing a current position of the control stick, and transforming the current position to a transformed position in the scaled first normalized unit-area movement space.

A multimedia operation system includes a display, a display driver, a desk, a display control panel, an input/output interface driver, and an application processor. The display driver drives the display to display images. The display control panel is disposed in the desk, and outputs an initiation signal according to a user's operation. The input/output interface driver receives the initiation signal and outputs a menu activation signal according to the initiation signal. The application processor executes an application to generate multimedia data, controls the display driver to drive the display for displaying application images of the multimedia data, and controls the display driver to drive the display for displaying a menu image when receiving the menu activation signal.
