Disclosed are a massage device providing a tinnitus treatment program and a control method therefor. According to an embodiment of the present disclosure, disclosed is a method by which a massage device provides a tinnitus treatment program. The method by which the massage device provides the tinnitus treatment program comprises the steps of: obtaining tinnitus information about a user; adjusting the magnitude of at least some of a plurality of frequency components included in a raw sound source and then flattening the raw sound source, so as to generate a first processed sound source; reducing the magnitude of at least some of a plurality of frequency components included in the first processed sound source on the basis of the obtained tinnitus information, so as to generate a tinnitus treatment sound source; and providing a tinnitus treatment program in which the generated tinnitus treatment sound source and tinnitus treatment massage are combined.

Systems and methods for enhancing wellness in a habitable space are provided. In some forms, an example system for enhancing wellness in a habitable space includes a control system having a processor, communication circuitry, and a memory. The communication circuitry of the control system is configured to communicate with one or more devices positioned within the habitable space. One or more sensors may also be positioned proximate the habitable space to detect indicia (e.g., biometric characteristics of a user, behavioral characteristics of a user, and environmental characteristics) and communicate the detected indicia to the control system. Based at least in part on the detected indicia, the control system is configured to trigger initiation of a scene in the habitable space by communicating a signal to at least one of the devices in the habitable space to adjust operation thereof.

Methods and systems are provided for measuring the capacitive state of an operator. The method includes placing an matrix array of pressure detection sensors in physical contact with the individual. The matrix array is integrated into the seat of the operator and continually measures the operator's presence and movement in the seat based on data received from the matrix array of pressure detection sensors. The breathing, movement and actigraphy patterns of the operator are measured and calculated based on the data received from the matrix array of pressure detection sensors. The breathing, movement and actigraphy patterns of the operator are continually analyzed to determine the capacitive state of the operator.

A biological information displaying apparatus according to an embodiment includes a picture obtaining apparatus and a processor. The picture obtaining apparatus obtains a picture signal of a predetermined site of a subject as a moving image. The processor generates a hue moving image by extracting a luminance or an image-based photoplethysmogram (iPPG) related to a pulse wave for each pixel of the moving image and assigning a hue in accordance with a value of luminance information or iPPG information. The processor displays the generated hue moving image such that the hue moving image is superimposed on an image of the subject.

A toilet device includes a toilet seat disposed on an upper side of a toilet; an image sensor provided on a back surface of the toilet seat and configured to image an inner space of a toilet bowl at time of excretion; an open-close acquiring device configured to acquire open-close information of the toilet seat; and an imaging controller configured to determine whether or not to image by the image sensor according to the open-close information of the toilet seat acquired by the open-close acquiring device.
