In common usage, a physical object or physical body (or simply an object or body) is a collection of matter within a defined contiguous boundary in 3-dimensional space. The boundary must be defined and identified by the properties of the material. The boundary may change over time. The boundary is usually the visible or tangible surface of the object. The matter in the object is constrained (to a greater or lesser degree) to move as one object. The boundary may move in space relative to other objects that it is not attached to (through translation and rotation). An object's boundary may also deform and change over time in other ways.
Distance determination to physical object
Embodiments presented herein relate to a wearable device (100) for echolocation arranged to be worn by a user. The wearable device includes a processing circuitry adapted to acquire, from at least one microphone operatively connected to the wearable device, a sound signal (S) of the user's footsteps or clapping. The processing circuitry is adapted to acquire, from at least one sensor operatively connected to the wearable device, a sensor reading (T) indicative of the user's footsteps or clapping. Thereafter, a direct sound signal (SDI) that corresponds in time with the sensor reading (T), and a reflected sound signal (SRE) of the user's footsteps or clapping, are identified. Based on the direct sound signal (SD)} and the reflected sound signal (SRE), both originating from the sound signal(S), a distance to at least one physical object (O) in the vicinity of the user is determined.
