Problems solved by technology

[0005] A disadvantage of the known balance belts is that the production is complicated
Another disadvantage of the known balance belts is that the belts are custom made, thus preventing the belt from being introduced to a wider public
Another disadvantage is that known balance belts are especially uncomfortable due to their bulkiness

Embodiment Construction

[0108] The following figures illustrate different embodiments in detail. Embodiments can be combined to achieve enhanced or improved technical effects. Examples of these combinations may be explicitly mentioned throughout, may be implied by the text, or may be implied. The same feature number in different figures may refer to the same feature.

[0109] figure 1 The vibrotactile feedback device 100 on the human body 10 or more specifically the torso 11 is schematically shown. The vibrotactile feedback device may be in the shape of a belt. The torso has a central axis 12 . When the trunk was upright, the central axis overlapped or coincided with the vertical line 25. If the torso is at an angle, the central axis will be at that angle with the vertical. Furthermore, a reference plane 20 is shown. The reference plane is perpendicular to or intersects the central axis.

Abstract

Loss of bilateral vestibular function is a chronic disease that may result from ototoxic, infectious, traumatic, autoimmune, or congenital causes. The purpose of the present invention is to improve the effectiveness of a vibrotactile feedback device. The present invention provides a vibrotactile feedback device for arrangement to a human body, comprising: a sensor arranged to sense a current posture of the human body relative to an environment; a haptic actuator arranged to allow the human body to perceive a posture deviation; an elongate carrier for holding the haptic actuator and the sensor in haptic communication with the human body and for holding the haptic actuator and the sensor substantially fixed relative to the human body; and a processing unit configured to: receive the current pose from the sensor; determining the posture deviation based on comparing the desired posture of the human body with the current posture; and transmitting an actuation signal to one or more of the haptic actuators based on the attitude deviation; wherein the haptic actuator is arranged to the carrier such that the haptic actuator is substantially arranged in a reference plane when the carrier is used; wherein the reference surface is functionally perpendicular to a central axis of a torso of the human body, and the reference surface intersects the torso to define a circumference to which the haptic actuators are arranged; and wherein the carrier comprises a stretchable material such that the relative distance between the haptic actuators and / or between the haptic actuators and the sensor is maintained irrespective of the length of the circumference.

Description

technical field [0001] The present invention relates to the field of vibrotactile feedback devices. Background technique [0002] Bilateral vestibular loss is a chronic condition that may result from ototoxic, infectious, traumatic, autoimmune, or congenital causes. And, in quite a few cases, the cause may be unknown. Patients with bilateral vestibular loss may feel unsteady and even occasionally fall for no reason, causing self-injury. [0003] In recent years, balance belts have been developed to help patients with bilateral vestibular loss maintain balance. A balance belt is basically a heavy belt that the patient wears around the waist. The belt contains sensors that sense the patient's upright posture and several haptic actuators placed in the belt. "Vibrotactile feedback improves balance and mobility in patients with severe bilateral vestibular loss" published December 5, 2018 in the Journal of Neurology. vestibular loss)" article describes the use of such belts. ...
