A method for managing focus in a graphical user interface using a directional controller that allows a directional or selection input. The method comprising: determining whether the input is directional or selection; determining whether there is a sibling object of a currently focused object in a given direction of the input if the input is directional; transferring the focus to the sibling object if there is a sibling object in the given direction; transferring the focus to an ancestor object of the currently focused object if there is no sibling object in the given direction; determining whether the currently focused object is a group; transferring the focus to a descendant object of the currently focused object if the currently focused object is a group and the input is selection; and selecting the currently focused object if the currently focused object is not a group and the input is selection.

An image display method of an Android platform based display device includes: monitoring the state of a mouse coupled to the display device to acquire a corresponding mouse event; creating a mouse cursor layer according to the acquired mouse event, and reporting a processing request of the mouse cursor layer to an upper level; and having a processor of the display device enable an auxiliary processing thread in response to the processing request of the mouse cursor layer to process the processing request of the mouse cursor layer so as to display a corresponding mouse cursor on a display screen of the display device. The image display method and the display method of the present invention effectively increase the response speed for a mouse cursor event, preventing lagging in displaying a mouse cursor and enhancing user experience.

Systems and methods for displaying a cursor and a focus indicator associated with real or virtual objects in a virtual, augmented, or mixed reality environment by a wearable display device are disclosed. The system can determine a spatial relationship between a user-movable cursor and a target object within the environment. The system may render a focus indicator (e.g., a halo, shading, or highlighting) around or adjacent objects that are near the cursor. The focus indicator may be emphasized in directions closer to the cursor and deemphasized in directions farther from the cursor. When the cursor overlaps with a target object, the system can render the object in front of the cursor (or not render the cursor at all), so the object is not occluded by the cursor. The cursor and focus indicator can provide the user with positional feedback and help the user navigate among objects in the environment.

A method of controlling an interactive display comprises receiving position data over time, where the position data represents the position of an input object relative to the interactive display. A velocity and acceleration of the input object are estimated, and a future position of the input object is predicted based on the estimated velocity and acceleration. This predicted future position is used to update the display.

A dual-system device and writing method and apparatus thereof, and interactive intelligent tablet includes a first system and a second system receiving touch data, where the data rendering speed of the first system is faster than that of the second system, and the data processing speed of the second system is faster than that of the first system; the first system acquiring data to be rendered from a target storage area, where the data to be rendered is generated by the second system according to the touch data and stored in the target storage area; the first system rendering the data to be rendered to obtain handwriting data to be displayed, and transmitting the handwriting data to be displayed to a display screen of the dual-system device for display. The disclosure solves the technical problem of writing delay of an external system when using dual-system to perform writing.

A computer mouse includes a lightweight shell housing for improved performance in electronic sports applications. The shell housing includes a plurality of openings that are defined by support members supporting the integrity of the shell, yet reduce the overall weight of the computer mouse. In exemplary embodiments, the support members and openings may be present on either the upper shell surface, the bottom shell surface, side surfaces and/or any combination of the above. In an exemplary embodiment, the openings may be hexagonal forming a honeycomb framework that provides a rigid housing but omits a substantial amount of material from the housing that provides a significant weight reduction.

An electronic device including a main body, a handle and a driven mechanism is provided. The main body includes a base and a button unit movably disposed on the base. The handle is movably connected to the main body. The handle is adapted to be rotated from a first position to a second position relative to the main body. The driven mechanism includes a first connection element and an ascending/descending assembly. A first section of the first connection element is fixed to the handle, and a second section of the first connection element is movably disposed in the base. The ascending/descending assembly is disposed in the base and located between the second section and a bottom of the button unit. When the handle is rotated from the first position to the second position, the first connection element moves with the handle, and the ascending/descending assembly is moved with the second section and lifts up the button unit.
