A smartwatch is configured to be usable to control a peripheral device. The smartwatch can be toggled between a typical or usual operating mode for a smartwatch and a mode for controlling the peripheral device. The toggling function is bound to a virtual button. Force applied to the virtual button is measured so that multiple functions, including the toggling function, can be accessed by applying different amounts of force to the button for a predetermined amount of time.

An analysis system has at least one monitoring assembly that includes at least one microphone to monitor an acoustic field proximate the monitoring assembly. The at least one microphone produces at least one microphone signal responsive to the acoustic field. The analysis system further includes a data storage device configured to buffer the at least one microphone signal and an audio analysis system configured to analyze a content of the data storage device where the audio analysis system is configured to analyze the content of the buffer to process at least a sound into a response or action.

A display device (10) and an image display method therefor, an image display system, and a storage medium, which relate to the technical field of display. A controller (101) of the display device (10) can adjust a gamma parameter when the temperature of a display module (102) is high, so as to reduce a drive voltage required by the display module (102) while keeping a brightness change of the display module (102) small. In this manner, the temperature of the display module (102) can be reduced, the display module (102) can be prevented from being damaged, and the display device (10) has a high reliability.

The present invention relates to a near-eye display device. The a near-eye display device includes a display, a first lens disposed in front of the display so as to be spaced apart from the display by a predetermined distance, a dynamic aperture adjustment element disposed adjacent to the first lens to dynamically control an aperture size of the first lens and a horizontal position of the aperture on a plane perpendicular to an optical axis, a main optics lens disposed to be spaced apart from the first lens by a predetermined distance, and a control system configured to control the dynamic aperture adjustment element.

A head-mounted device includes a first light field camera, a second light field camera, a first light field display, a second light field display and a supporting structure. Each of the first light field camera and the second light field camera includes, in order from an object side to an image side, a lens group, a collimator and an image sensor. Each of the lens groups includes a plurality of lens units. The lens units are arranged in a two-dimensional lens array, and each of the lens units includes a lens container and a plurality of lens elements. A first engaging structure is disposed between at least two adjacent lens elements of the lens elements.

Displaced haptic feedback can be provided to a person providing an input on a user interface. The user interface can be operatively connected to a processor. The processor can be configured to receive an input signal from the user interface. Responsive to receiving the input signal, the processor can be further configured to cause a haptic device to be activated. The haptic device can be physically separated from the user interface. The haptic device can provides a haptic feedback to a user interacting with the user interface.

Various embodiments of a wearable haptic and thermal feedback display system are disclosed herein. In particular, the system includes an array of vibrotactile actuators and thermal units affixed on a flexible casing that could be worn around the forearm. The collocated vibrotactile and thermal stimulations could enable richer haptic communication due to better control over the generated patterns. In addition, the device could be wirelessly controlled using a smartphone which further proves its applicability in long distance haptic communication

The present invention discloses an indoor Electronic Traveling Aid (ETA) system for blind and visually impaired (BVI) people. The system comprises a headband, intuitive tactile display with myographic (EMG) feedback, controller, and server-based methods corresponding to three operation modalities. In 1.sup.st modality, sighted users mark routes, map navigational directions, and create semantic comments for BVIs. This information of routes is continuously collected and estimated in ETA servers. In the 2.sup.nd modality, BVIs choose the routes from servers, thereby, are supplied with real-time navigational guidance. Also, an EMG interface is used, where the user's facial muscles are enabled is to send commands to the ETA system. In the 3.sup.rd modality, BVIs receive real-time audio guidance in complex or unforeseen situations: ETA provides a crowd-assisted interface and real-time sensory (e.g., video) data, where crowd-assistants analyze the situation and help the BVI to navigate.

A method to assess user condition for wearable devices using electromagnetic sensors is provided. The method includes receiving a signal from an electromagnetic sensor, the signal being indicative of a health condition of a user of a wearable device, selecting a salient attribute from the signal, and determining, based on the salient attribute, the health condition of the user of the wearable device. A non-transitory, computer-readable medium storing instructions which, when executed by a processor, cause a system to perform the above method, and the system, are also provided.

Methods and apparatus to determine user presence are disclosed. A disclosed example monitoring device to determine of a presence of a user in a metering environment includes a mount to couple the monitoring device to a wearable device to be worn by the user, the wearable device to receive content from a content device, a sensor to detect motion of the user, and a transmitter to transmit motion data pertaining to the detected motion of the user for the determination of the presence of the user.
