Способ акустического представления пространственной информации для инвалидов по зрению относится к созданию приборов для ориентирования в окружающем пространстве. Известные технические системы, как правило, представляют собой ультразвуковые локаторы, работающие в диапазоне 40 - 120 кГц. Для восприятия слуховым анализатором человека отраженный сигнал необходимо перевести в область звуковых частот, что осуществляют с помощью выделения низкочастотной огибающей. При этом воспринимаемый слуховым анализатором сигнал содержит информацию главным образом с дистанции до объекта. В предлагаемом способе с целью согласования частотного и временного диапазонов акустического сигнала со слуховым анализатором используется изменение временного масштаба отраженного сигнала в каждом канале приема. Излучается ультракороткий зондирующий импульс. В этом случае эхо-сигнал близок к импульсной характеристике объекта. Восприятие инвалидом по зрению сигналов, отраженных от нескольких ближайших объектов, позволяет ...

A sensory array detects objects in an environment surrounding the user, such as a fireman or blind person, when the device is being worn, a tactile display to physically engage the user's body and to provide salient information about said environment. An algorithm controls one or both of the sensory array and tactile display so that the presentation of an object is adapted to circumstances other than the physical parameter of the object's proximity to the user. The output can therefore be tuned to provide salient feedback, based on the rate of change of position of the object with respect to the user, the physical attributes of the object, the time since first detection of the object by the electromagnetic or sonic sensory array; and/or the current situation or objectives of the user. This ensures that the user does not get too many distracting tactile responses for the user to understand their environment from vibrotactile stimulation of the skin.
