Action recognition and tracking of construction heavy equipment is the first step for benchmarking and analyzing the performance of individual machines and evaluating the productivity of a jobsite as a whole. Aside from direct observations, the current approaches for automatically recognizing and tracking various actions of construction heavy equipment includes: 1) using active sensors such as ...

This paper describes the audio component of a virtual reality system that uses remote sensing to free the user from body-mounted tracking equipment. Position information is obtained from a camera and used to constrain a beam-forming microphone array, for fareld speech input, and a two-speaker transaural audio system for rendering 3D audio. 1 Vision Steered Beam-Forming 1.

For researchers and engineers working on speech or audio signal processing, to implement and evaluate processing algorithms on specific devices such as DSP or FPGA is necessary for realizing real time signal processing applications. Furthermore, evaluation of algorithms in real world environment is very important. However, conventional evaluation boards are not portable or quality of sound inte...
