“…Lab systems have demonstrated concepts including obstacle detection based on stereoscopic images [10] and radar based indoor navigation [11]. Vision systems without displays have also been explored including Merino-Gracia et al's [12] head-mounted camera system for real time text recognition with text-to-speech audio.…”

Abstract. Recent advances in low cost wearable computers opens up new possibilities for the development of innovative visual aids. A head-mounted display with cameras that capture views of the physical world, a wearable computer can process the image and present an augmented view to the user. Although, some research is reported into the development of such visual prosthetics the functionalities often appear ad-hoc. This study set out to identify what functionality visually impaired users need in various contexts to reduce barriers. Information was gathered via interviews of visually impaired individuals. The results show that recognizing faces and text is the most important functions while the idea of smart glasses where questioned.

Abstract-Modelling in 3D is considered time-consuming and difficult, relying on special skills. To make matters worse, there are currently no user interface conventions for how to work with 3D data and different modelling applications adopt varying interaction techniques. This paper thus presents a framework for simple 3D modelling based on 2D drawings of height maps. The framework is intended to be quick and easy to use for untrained users and no special software is needed as the application runs in the browser. An experimental evaluation confirmed that all of the eight participants successfully managed to complete simple modelling tasks in just a few minutes.
