The invention relates to a method for determining kinetosis in a vehicle user of a vehicle during at least one travel event in which at least one body part of the vehicle user is monitored, as a result of which image data are generated. Driving dynamics of the vehicle are monitored as the vehicle is being driven, as a result of which driving dynamics data are generated for every travel event while the vehicle is in motion. The image data are evaluated to determine the formation of sweat on the at least one body part of the vehicle user, as a result of which approximated electrodermal activity data are generated. The driving dynamics data are associated with the approximated electrodermal activity data, as a result of which the kinetosis of the vehicle user in at least one of the travel events is determined.

A system and/or method that uses a body posture of a user to determine and modulate a content mode of a virtual reality system. The content mode may define the manner in which virtual reality content is presented to the user and/or the manner in which the user interacts with the virtual reality content. The user's body posture and/or a change in body posture may cause the content mode and/or the virtual reality content to change accordingly. In some implementations, primary content may be presented to the user according to a first content mode in response to the user sitting. Secondary virtual reality content may be presented to the user according to the second content mode in response to the user standing. As such, a user may initiate a change in the virtual reality content and/or the content mode by standing from a sitting posture and/or sitting from a standing posture.

The present invention relates to a terahertz biometric imaging package comprising: an image sensor comprising an antenna pixel array arranged to detect terahertz radiation transmitted from an object, for capturing an image, each antenna pixel comprises a power detector including an antenna structure for receiving terahertz radiation, wherein the power detector is configured to convert a detected terahertz radiation to a sensing signal at a lower frequency than the frequency of the terahertz radiation, a package top cover arranged to cover the antenna pixel array, wherein the image sensor is configured to capture a terahertz image of an object located on an opposite side of the package top cover, a package bottom part arranged on the other side of the antenna pixel array opposite from the package top cover, wherein the antenna pixel array is encapsulated between the package top cover and the package bottom part.

An electric signal transmission device including an electrode 11, disposed to be opposed to an electrogenic cell, and for sending and receiving electric signals to and from the electrogenic cell via the electrode 11.

Systems and methods for determining whether to enable color blind accessibility settings within the course of a user interactive narrative are described herein. Virtual color blindness indication objects containing colors that are visibly distinguishable within a single dichromatic visual spectrum can be utilized in objectives to determine a user's dichromatic visual deficiency type.

An oral appliance for treating sleep apnea in a user includes a mouthpiece configured for being positioned in an oral cavity of the user, and at least one pulse oximeter attached to the mouthpiece. According to an aspect, the pulse oximeter is configured to monitor actual oxygen saturation levels of hemoglobin of the user when the oral appliance is positioned in the oral cavity of the user. The oral appliance may include an additional sensor attached to the mouthpiece that includes at least one of an airflow sensor, a pressure sensor, a noise detector, and an actigraphy sensor.

A wearable system configured to collect thermal measurements related to respiration. The system includes a frame configured to be worn on a user's head, and at least one non-contact thermal camera (e.g., thermopile or microbolometer based sensor). The thermal camera is small and lightweight, physically coupled to the frame, located close to the user's face, does not occlude any of the user's mouth and nostrils, and is configured to take thermal measurements of: a portion of the right side of the user's upper lip, a portion of the left side of the user's upper lip, and a portion of the user's mouth. The thermal measurements are forwarded to a computer that calculates breathing related parameters, such as breathing rate, an extent to which the breathing was done through the mouth, an extent to which the breathing was done through the nostrils, and ratio between exhaling and inhaling durations.

Numerous aspects of communication devices, methods, and systems are described in this application. One aspect is a system comprising a body having a skin facing surface and an opposing surface and an energy generator operably coupled to the body and comprising a plurality of generator elements operable to output a plurality of different energy types in a signal direction toward skin. Each generator element of the plurality of generator elements may be independently operable to output one energy type of the plurality of different energy types in the signal direction. When the skin facing surface of the body is positioned relative to the skin, the energy generator may affect tissues associated with or adjacent to the skin by causing one or more generator elements of the plurality of generator elements to output an energy signal in the signal direction with one or more different energy types.

A non-invasive system and method are provided. Brain activity of a user is detected using a non-invasive brain interface when the user is exposed to an external stimulus. The user is determined to be negatively primed by the external stimulus based on the detected brain activity. An alert that the user is being negatively primed by the external stimulus is automatically provided. A tagged training session may be automatically provided to the user in response determining that the user has a negative mental state, thereby promoting a positive mental state of the user. A training session list containing the tagged training session may be automatically modified based on the determined mental state of the user.

A method of determining olfactory perception signature of a subject is disclosed. The method comprises: providing the subject with a plurality of physical odorant samples for sniffing; for each sniffed odorant sample, presenting to the subject, by a user interface, a set of odorant descriptors and a respective set of rating controls, and receiving ratings entered by the subject using the rating controls. Each rating is indicative of a descriptiveness of a respective odorant descriptor for the odorant sample, thereby obtaining a set of descriptiveness levels for the odorant sample. The method also comprises calculating, by a computer, relations between pairs of sets of descriptiveness levels corresponding to pairs of odorant samples, to provide a vector of relations, wherein the vector represents the olfactory perception signature of the subject.
