Echolocation by the blind – influence of signal type and directionality of the sound source on acoustic localization of obstacles
Introduction
Human echolocation is a confirmed and relatively well-documented phenomenon which allows blind persons to localize obstacles or perceive layouts of their surroundings using reflected sounds. Recently a number of studies have been devoted to analyzing the mechanism of echolocation and various factors affecting it, e.g. why some blind persons more easily become expert echolocators or how the mouth-clicks produced by experts differ from the average person.
Development of a device supporting the early diagnosis of skin nevi, including melanoma, using computer vision methods, spatial modeling, comparative analysis and classification
Introduction
Objective: design and construction of an automated high-resolution device for automatic 3D modeling and analysis of the patient's skin surface and for the identification of pigmented lesions for secondary prevention of skin cancer.
