The goal of the Portuguese project "SmartVision: active vision for the blind" is to develop a small, portable and cheap yet intelligent and reliable system for assisting the blind and visually impaired while navigating autonomously, both in-and outdoor. In this article we present an overview of the prototype, design issues, and its different modules which(More)
Building a general-purpose, real-time active vision system completely based on biological models is a great challenge. We apply a number of biologically plausible algorithms which address different aspects of vision, such as edge and keypoint detection, feature extraction, optical flow and disparity, shape detection, object recognition and scene modelling(More)
1 — Senior citizens, very young children and users with different kinds of impairments are often prevented from enjoying the benefits of latest technologies for assistance, accessibility and usability, often due to unfriendly or expensive interfaces. We present a friendly and inexpensive system that allows one to interact with a computer, using only a few(More)
The interest in cognitive robotics is still increasing, a major goal being to create a system which can adapt to dynamic environments and which can learn from its own experiences. We present a new cognitive SLAM architecture, but one which is minimalistic in terms of sensors and memory. It employs only one camera with pan and tilt control and three(More)
Human-robot interaction is an interdisciplinary research area that aims at the development of social robots. Since social robots are expected to interact with humans and understand their behavior through gestures and body movements, cognitive psychology and robot technology must be integrated. In this paper we present a biological and real-time framework(More)
— Human-robot interaction is an interdisciplinary research area which aims at integrating human factors, cog-nitive psychology and robot technology. The ultimate goal is the development of social robots. These robots are expected to work in human environments, and to understand behavior of persons through gestures and body movements. In this paper we(More)
Ultrasonic, infrared, laser and other sensors are being applied in robotics. Although combinations of these have allowed robots to navigate, they are only suited for specific scenarios, depending on their limitations. Recent advances in computer vision are turning cameras into useful low-cost sensors that can operate in most types of environments. Cameras(More)
This paper presents the research conducted to provide low cost traffic monitoring solution to the ever increasing traffic congestion problems in Pakistan. The embedded system created is a low-power system that can replace the expensive and complicated systems that add up to the high installation and controlling costs. The feasibility is demonstrated with(More)
