The present invention provides methods and systems that provide for reliable, convenient, and noninvasive assessment of hydration status. The methods and apparatuses can use the temporal sequence of the aortic value opening and closing along with the user's body position to derive parameters that determine the hydration status of the user. The user can use this information to make near-term lifestyle changes that can improve physical performance, health, and general wellbeing.

A medical diagnostic apparatus includes a controller; a user interface; a platform having a horizontal surface; and at least one visible light image sensor positioned below the horizontal surface that is capable of producing a diagnostic visible light image of a bottom portion of a foot or feet positioned on the horizontal surface. At least a portion of the horizontal surface is transparent to visible light. The apparatus may further include at least one infrared image sensor positioned below the horizontal surface that is capable of producing a thermal image of the first target area. The apparatus may further include sensors positioned above the platform capable of producing diagnostic visible light images or thermal images of a top portion of the user's foot or feet. The apparatus may further include a weight measurement system coupled to the platform.

In an example, the technique also detects and measures vital signs of each human target by continuous, non-intrusive method. In an example, the vital signs of interest include a heart rate and a respiratory rate, which can provide valuable information about the human's wellness. Additionally, the heart rate and respiratory rate can also be used to identify a particular person, if more than two target humans living in a home. Of course, there can be other variations, modifications, and alternatives.

A device and method for detecting, documenting, measuring and mapping the size, shape and location of lesions underlying the surface of the skin or other soft tissue in a subject by measuring variations in the tactile pressure of the skin or other tissue surface being investigated through the use of a capacitive tactile sensor is described. A capacitive tactile sensor comprises at least one exposure window, a substrate comprising a plurality of electrodes disposed within the housing, an insulating layer, a non-conductive compressible membrane and covering positioned over the insulating layer wherein at least a portion of the membrane is accessible via the exposure window, and a controller configured to calculate at least one parameter of a tissue of a subject. A method of measuring a tissue parameter in a subject and a method of performing a self-guided examination on a tissue of a subject are also described.

An ear-wearable device, such as a hearing aid or earbud, includes a plurality of biometric sensors configured to generate sensor measurements indicative of at least an aspect of contact between the housing of the ear-wearable device and the ear canal of the user, and compares the sensor measurements to a stored profile in order to determine whether an authorized user is wearing the ear-wearable device.

The present technology relates to information processing apparatus and method, and a program that make a stress level controllable depending on circumstances. A stress level measuring unit measures a stress level of a user on the basis of a result of detection by various types of sensors included in an input unit. A stress factor specifying unit specifies a factor causing an increase or decrease in the stress level on the basis of an action of the user in a period in which the stress level is increased or decreased. The present technology is applicable to a stress control system, for example.

The present disclosure relates to digital solutions for eye-contact training. According to a first aspect, the disclosure relates to a computer-implemented method for eye-contact training. The method comprises presenting S1, on the one or more displays, one or more user interface objects indicative of one or more desired gaze areas representing one or more spectators of a virtual audience of the user. The method further comprises obtaining S3, using the camera, eye-gaze data indicative of the user's actual gaze direction and evaluating S4 a level of eye contact between the user and the virtual audience based on one or more rules defining a level of eye contact. The method also comprises providing S5 user feedback indicative of the evaluated level of eye-contact to the user. The disclosure also relates to an electronic user device and to a computer program configured to perform the method.

For generating a breathing alert is disclosed, a method receives a video stream of a subject. The method further estimates a breathing signal from the video stream. The method determines one of a large-scale motion and/or a breathing event of the subject based on the breathing signal. The method generates an alert if both no breathing event is identified and no large-scale motion of the subject is identified within an event time interval.

Embodiments and examples are disclosed for intelligent vehicle diagnostics using driving behavior modeling and monitoring. For one example, a data processing system for a vehicle includes a plurality of sensors and a vehicle control unit (VCU). The VCU may sample the output from each of the plurality of sensors and assemble a dataset which may be transmitted to a cloud computing center. The cloud computing center may apply statistical machine learning algorithms to the dataset and training data to develop a model of a user's expected driving behavior. The cloud computing center may transmit the model to the vehicle, wherein the VCU may utilize the model to monitor the user's driving behavior. In response to detecting driving behavior that is anomalous to the expected driving behavior, the VCU may diagnose the cause of the anomalous behavior and take one or more preventative actions based on the diagnosis.

Provided is a technique capable of prompting execution of highly useful blood pressure measurement. That is, the blood pressure measuring apparatus according to an aspect of the present invention is a blood pressure measuring apparatus for performing blood pressure measurement, the blood pressure measuring apparatus including a notification unit that performs a notification to prompt a user to perform the blood pressure measurement, a time setting unit capable of setting a blood pressure measurement time by an instruction from the user, a storage unit that stores a recommended time period of the blood pressure measurement, and a control unit that performs control to cause the notification unit to start the notification based the blood pressure measurement time set by the time setting unit, and cause the notification unit to stop the notification when the recommend time period passes.
