We propose a method for identifying a piano keyboard present in the video footage of a standard webcam with the goal of teaching chords, scales and suggested finger positions to a beginner pianist. Our keyboard identification method makes use of binary thresholding, Sobel operators and Hough transforms, as well as proposed algorithms specific to this application, to first find an area resembling a...
In this paper we present a novel interaction framework for augmented reality, and demonstrate its application in an interactive AR exposure treatment system for the fear of spiders. We use data from the Microsoft Kinect to track and model real world objects in the AR environment, enabling realistic interaction between them and virtual content. Objects are tracked in three dimensions using the Iterative...
In this paper, we describe a user study evaluating the usability of an augmented reality (AR) multimodal interface (MMI). We have developed an AR MMI that combines free-hand gesture and speech input in a natural way using a multimodal fusion architecture. We describe the system architecture and present a study exploring the usability of the AR MMI compared with speech-only and 3D-hand-gesture-only...
