چکیده
The paper addresses an analysis of two elenlents necessary for vision systems for blinds ant1 robots definition. One of them is an analysis of some nlost popular and advanced projects of technological assistances for blinds' independent and secure displacetnents in non-cooperating environment,. Thc sccond is an analysis of human scene perception characteristics. The analysis results in concel)tual principle definitioil whicll should be integrated in technological assistance for blinds based on artificial vision only. Intelligent glasses, presented in this paper, are one of them. The intelligent glasses offer a global environment perception, fixed and nloving obstacles detection, and tactile representation of them. Rlilids can than know at any time, by sillall tactile interface fast scauling , wllere is the free place in their nearest spatial neighbourl~ood. All the environment analysis and interpretation are based upon two (general, and not orlly stereo) images. The proposed system clesign principles can be easily simplified for humanoid robots.

We show that after dark-adaptation colour-blinds had lower light perception thresholds than colour-normals (0.44 log-units), which may give a selective advantage under sc...
