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.

A method and system for hand-object interaction dataset collection is described herein, which is configured to support user-specified collection of hand-object interaction datasets. Such hand-object interaction datasets are useful, for example, for training 3D hand and object pose estimation model. The method and system adopt a sequential process of first recording hand and object pose labels by manipulating a virtual bounding box, rather than a physical object. Naturally, hand-object occlusions do not occur during the manipulation of the virtual bounding box, so these labels are provided with high accuracy. Subsequently, the images are separately captured of the hand-object interaction with the physical object. These images are paired with the previously recorded hand and object pose labels.

The present techniques provide a method, apparatus and system for high-speed acoustic levitation, for example high-speed acoustic holography or other applications. A novel technique is presented that allows high-speed multi-point levitation even in the presence of arbitrary sound-scattering surfaces and demonstrates a process that works in the presence of any physical object. Embodiments provide a simplified approach for determining locations of traps in a working volume which may also be termed an acoustic volume or acoustic chamber. Moreover, embodiments provide an approach for determining the location of traps by determining a contribution of a scattering surface in the working volume and a contribution from a target object in the working volume.
