A system that enables a person to program without typing is needed because of the high incidents of repetitive stress injuries among people who program. This paper presents a design for a system that generates environments that enables people to program by voice and a method of determining if the system is successful. It also shows how this generator can be used to support entering data and writing XML documents.

From a fundamental perspective, image reconstruction tasks in both ultrasound pulse echo and photoacoustic imaging are identical. We propose a C-scan imaging scheme that is applicable to both modalities where the image reconstruction is achieved through focusing action of an acoustic lens. The theory to characterize the imaging system is presented. Experimental methodology to determine the system point-spread-function is outlined and demonstrated with preliminary results.
