A smart laser phone includes a main body with a mobile communication module, a band connected to the main body, an optical member, on a side surface of the main body to which the band is not connected, for projecting a laser image, a speaker on the same side surface as the optical member but separated by a set distance therefrom, a sensor unit on the surface between the optical member and the speaker, and a microphone on the outer side of the optical member. When the smart laser phone is worn on the wrist, the microphone and the optical member, the sensor unit and the speaker are sequentially equipped on the side surface of the smart laser phone main body oriented toward the palm, and thus, as the phone is used with an enlarged image, using the phone is convenient, and communication can be carried out with clear sound.

To provide a startup UI presentation portable device capable of automatically presenting a preset UI highly likely to be used next in the current posture when returned from a sleep mode, the portable device (1), when returned from the sleep mode (S1), determines whether the posture (S2) of the portable device (1) sent from a built-in acceleration sensor is within a specified range of a reference posture predetermined for each of a camera, a projector and a direction indicator (S3). When the posture is within the specified range (YES in S3), the portable device (1) displays a startup UI (icon) previously associated as a startup UI for a function most likely to be used in the reference posture on a display screen (S5). The display of the startup UI is performed automatically subsequent to release of the sleep mode, without requiring an unlock operation or password entry.

An image display system includes a reflecting screen that has a reflecting surface. The reflecting surface includes hologram which reflects narrow bands of spectrum of incident lights toward desired direction. A projection display system includes a reflecting mirror(s) with hologram so that the image can be projected nearly vertical or short distance. This invention can be used as a head-up-display with improved brightness and eliminating ghost noise.

Systems, methods, devices and non-transitory, computer-readable storage mediums are disclosed for a wearable multimedia device and cloud computing platform with an application ecosystem for processing multimedia data captured by the wearable multimedia device. In an embodiment, a body-worn apparatus comprises: a camera; a depth sensor; a laser projection system; one or more processors; memory storing instructions that when executed by the one or more processors, cause the one or more processors to perform operations comprising: capturing, using the camera, a set of digital images; identifying an object in the set of digital images; capturing, using the depth sensor, depth data; identifying a gesture of a user wearing the apparatus in the depth data; associating the object with the gesture; obtaining data associated with the object; and projecting, using the laser projection system, a laser projection of the data on a surface.

Various embodiments herein include systems, methods, and software for an mobile entertainment projection device. In addition to projecting entertainment content, the projection device includes a camera for capturing user motion and a graphical display that is arranged to be altered in response to detection of user motion as captured by the camera. Two or more systems may also be used to display a continuous image, such as in projecting streaming video.

An adjustable device projection system includes a main housing, a base, and a device holder. The main housing has a lens defining a focal axis. The base is coupled to and extends from the main housing. The device holder is coupled to the base and is configured to hold a mobile device generally in optical alignment with the at least one lens. The system may include an adjuster to adjust the mobile device relative to the lens or adjust an orientation of the focal axis. The adjuster may include a track along which the device holder adjustably slides. The adjuster may include a support configured to adjust an orientation of the focal axis. A kit including the adjustable device projection system and a light board system configured to display images projected via the projection system.

Systems and methods are provided for coordinating presentation of audio data using a head-worn wearable device. The method includes, while an associated electronic device is in proximity to the head-wearable device and the electronic device is presenting audio data, in accordance with a determination that sensor data received at the head-wearable device indicates that a precondition for presenting audio data is present at the head-wearable device, ceasing to cause presentation of the audio data at the electronic device and causing presentation of the audio data at the speaker of the head-wearable device. The method includes, in accordance with a determination that the sensor data received at the head-wearable device indicates that the precondition for presenting audio data is no longer present at the head-wearable device, ceasing to cause presentation of the audio data at the head-wearable device, and causing presentation of the audio data at the electronic device.

A projection method includes: after determining a first application in response to a display request sent by a second electronic device, the first electronic device determines an application running mode supported by the first application, where the application running mode corresponds to one or more electronic device types. Then, the first electronic device sends first projection data of the first application to the second electronic device based on a first application running mode in the application running mode, where the first projection data is used to cause the second electronic device to display the first application in the first application running mode.

A method for controlling an electronic device that executes and displays an application is provided. The method includes displaying an execution screen of the application on a touch screen, projecting and displaying a projection image corresponding to the execution screen of the application, displaying a pointer on the projection image, and moving and displaying the pointer on the projection image to correspond to a gesture detected on the touch screen.
