Computing interface systems and methods are disclosed. Some implementations include a first accelerometer attached to a first fastening article that is capable of holding the first accelerometer in place on a portion of a thumb of a user. Some implementations may also include a second accelerometer attached to a second fastening article that is capable of holding the second accelerometer in place on a portion of a wrist of a user. Some implementations may additionally or alternatively include magnetometers and/or gyroscopes attached to the first and second fastening articles. Some implementations may also include a processing device configured to receive measurements from the accelerometers, magnetometers, and/or gyroscopes and identify, based on the measurements, symbols associated with motions of a user's hand and/or the orientation of the hand. Some implementations may allow a user to control a cursor in a three dimensional virtual space and interact with objects in that space.

A system which, with data provided by one or more sensors, detects a user's alteration of the geometries of parts of his face, head, neck, and/or shoulders. It determines the extent of each alteration and normalizes it with respect to the maximum possible range of each alteration so as to assign to each part-specific alteration a numeric score indicative of its extent. The normalized part-specific scores are combined so as to produce a composite numeric code representative of the complete set of simultaneously-executed geometric alterations. Each composite code is translated, or interpreted, relative to an appropriate context defined by an embodiment, an application executing on an embodiment, or by the user. For example, each composite code might be interpreted as, or assigned to, a specific alphanumeric letter, a color, a musical note, etc. Through the use of this system, a user may communicate data and/or commands to a computerized device, while retaining full use of his hands and his voice for other tasks, and while being free to focus his visual attention on something other than the system.

A method, device and system for transmitting information. A first user device acquires input information of a first user in an input box, displays information in a current input line in a corresponding biggest available font on the basis that a total display width of the information in the current input line is less than or equal to a line display width of the input box, and sends, when acquiring an information sending operation of the first user, the information in the input box to a second user device via a network device, and the second user device receives and displays the information in the input box. A layout operation is performed in the corresponding biggest available font on the basis that the total display width of the information in the current input line is less than or equal to the line display width of the input box.

A device can receive input indicating an intersection of two or more roads. The device can identify the two or more roads included in the input using an indicator. The device can determine a geographic location of another device using information that identifies the geographic location received from the other device. The device can identify a data structure that includes information identifying a set of intersections associated with the geographic location. The device can perform a search of the two or more roads using the information identifying the two or more roads and the information included in the data structure. The device can determine a priority for one or more results of the search for the intersection after performing the search of the two or more roads. The device can provide the one or more results of the search for the intersection to permit and/or cause an action to be performed.

A key scanning method, a scan method for a key scan circuit, and an input device thereof are provided. The key scanning method comprises performing a first scan procedure which includes triggering a first main scan line and reading electrical signals received via a plurality of signal sensing lines to determine whether any of the keys among a first key group is triggered. Then, performing a second scan procedure which includes triggering at least one of a plurality of secondary scan lines and reading the electrical signals received via the plurality of signal sensing lines to determine whether any of the keys among a second key group is triggered. In the key scanning method, the first scan procedure and the second scan procedure are performed one after another, and each of the secondary scan lines is triggered at least once.

This disclosure describes operations for operating a touch-sensitive keypad. The operations include: detecting, during a normal operating mode of the keypad, activation of one or more keys of the keypad, the normal operating mode causing the keypad to register a value corresponding to a given key when the given key is activated for a first amount of time; determining that the activation of the keys of the keypad satisfies a visual impaired mode criterion; in response to determining that the activation of the keys of the keypad satisfies the visual impaired mode criterion, transitioning the operating mode of the keypad from the normal operating mode to a visual impaired mode; and registering, during the visual impaired mode, the value corresponding to the given key in response to determining that the given key has been activated for a second amount of time that is longer than the first amount of time.

Aspects of the present disclosure are directed to creating and administering artificial reality collaborative working environments and providing interaction modes for them. An XR work system can provide and control such artificial reality collaborative working environments to enable, for example, A) links between real-world surfaces and XR surfaces; B) links between multiple real-world areas to XR areas with dedicated functionality; C) maintaining access, while inside the artificial reality working environment, to real-world work tools such as the user's computer screen and keyboard; D) various hand and controller modes for different interaction and collaboration modalities; E) use-based, multi-desk collaborative room configurations; and F) context-based auto population of users and content items into the artificial reality working environment.
