Bilateral vestibular loss is a chronic condition of which the causes can be ototoxic, infectious, traumatic, autoimmune or congenital. An object of the invention is to improve the effectiveness of a vibrotactile feedback arrangement. The current invention provides a vibrotactile feedback arrangement for use arranged to a human body, comprising: a sensor arranged for sensing a current attitude of the human body relative to the environment; tactile actuators arranged for allowing the human body to perceive an attitude deviation; an elongated carrier for holding the tactile actuators and the sensor in tactile communication with the human body and for holding the tactile actuators and the sensor substantially fixed relative to the human body; and a processing unit configured for: receiving the current attitude from the sensor; determining the attitude deviation based on comparing a desired attitude of the human body with the current attitude; and transmitting an actuation signal to one or more of the tactile actuators based on the attitude deviation; wherein the tactile actuators are arranged to the carrier such that, when the carrier is used, the tactile actuators are arranged substantially in a reference plane; wherein the reference plane is functionally perpendicular to a central axis of a torso of the human body and the reference plane intersects the torso to define a circumference, wherein the tactile actuators are arranged to the circumference; and wherein the carrier comprises stretchable material such that the relative distance between the tactile actuators and/or between the tactile actuators and the sensor is maintained independent of the length of the circumference.

An electrical connector includes a male element and a female element configured to form a rivet for fastening the electrical connector to a piece of material; and a neck washer, which has a washer portion and a neck portion and which is configured to be placed between the male element and the female element of the rivet. The washer portion is configured to form an electrical connection area for an electrical conductor of the piece of textile and the neck portion is configured to electrically connect the washer portion to at least one of the male element and the female element. The electrical connector can be used independently of the position of the electrical conductor in relation to one or more layers of materials in the piece of material.

From a first sensor in a set of sensors, a set of sensor measurements corresponding to a wearer of a garment is collected. Using a model and the set of sensor measurements, a performance deviation index corresponding to the wearer is determined, the performance deviation index corresponding to a deviation from a baseline performance level of the wearer. Responsive to the performance deviation index being above a threshold, a characteristic of the garment is altered.

Color changing systems include a color changing article or device that includes a color, text, and pattern changing hardware. Smart devices or other standalone controllers provide software instructions to the color changing hardware to produce colors, patterns, and text which appear on the articles or devices. A software app running on the smart device or standalone controller initiates a method of changing colors, text, and patterns of apparel, devices, hard goods, and accessories. The color changing systems include fabrics and other materials including LEDs, LED fiber optic fabrics, electroluminescence (EL), bioluminescence, electrochromatics, E-ink, OLED, light guides, printed nano LEDs, photonic ink, and other materials. The systems selectively apply an analog voltage or data stream to the output material to produce an article with a selected color, text, or pattern. A camera or color detector can be used to select colors for display.

A modular sound modulation system that may be incorporated into a wearable harness for use beneath a costume or clothing. The system includes a sound modulation unit having an amplifier and programmable sound modulation controller. Power is provided via a wired remote power supply. Speakers are disposed at key locations to cause modulated sound to appear to come from the head of the costume. A high-fidelity microphone captured vocalizations from the wearer. The system may further include a transmitted to broadcast or store a recording of the modulated sound.

A fabric article (100) comprising a continuous body of knitted fabric (100). The continuous body of fabric (100) comprises: a base component (101) comprising a plurality of courses of nonconductive yarn and a sensing component (107) comprising a first conductive region (109).
