Touch at a distance : underwater object identification using pressure sensors
… environment, the case of a foil passing a static object in still water is analyzed. A two-dimensional potential flow approach based on a source panels method is used to characterize the spatio-temporal pressure signature of the object as sensed by the vehicle. Simulations are used to estimate the …

Hover : A wearable object identification system for audio augmented reality interactions
We design, implement, and test a wearable object identification system which allows users to "hover" their hands over objects of interest and get access to contextual information that may be tied to them, through an intelligent personal assistant. The system uses a fusion of sensors to be able to …

A multi-level brain-computer interface for object recognition and object identification
… designed to decode a user's intention towards an object, determining whether it pertains to object recognition or identification, and then channel the data to an algorithm trained specifically for those tasks. It consists of two principal components: one algorithm crafted to differentiate between …

Ubiquitous Metadata: Design and Fabrication of Embedded Markers for Real-World Object Identification and Interaction
… robust and efficient methods to connect physical objects with their virtual counterparts. In this thesis, we present a novel approach to bridging this gap through the design, fabrication, and detection of embedded machine-readable markers. The vision of mixed reality relies on mobile and wearable …

Influence of spatial cues on the identification and the localization of objects in the auditory foreground
The ability to form auditory objects is important in the natural environment where sounds arriving at our ears are a resultant of all spectro-temporal components that may have arisen from different auditory events. It has been shown that auditory spatial cues are effective for grouping acoustical …
