Control system of didactic device for visually impaired

U sklopu ovoga rada razvijen je sustav upravljanja didaktičkim uređajem za slijepe osobe. Ukratko su opisane tehnologije koje u danas dostupne slijepim i slabovidnim osobama. Iz dana razvija se sve više i više novih stvari koje bi im što više olakšale život. Nadalje, opisane su glavne komponente koje su korištene u izradi ovog sustava. Razvijeni sustav sastoji se od upravljačke ploče i pet didaktičkih uređaja. Oba dijela su u potpunosti hardverski napravljena te je svaki dio detaljno upisan. Također, je razvijena programska podrška te jedinstveni protokoli za komunikaciju između njih. Za kraj su dana mjerenja određenih signala te je izračunata potrošnja cijelog sustava.As part of this master thesis, the control system of didactic device for visually impaired was developed. A brief description was given of the technology available today for the blind and visually impaired people. New technology that would ease living for them is developed on a daily basis. Furthermore, the main components used in developing this system were described. Developed system consists of a controlling board and five didactic devices. The hardware was made for both those parts and each part was thoroughly described. Also, the software was developed along with the unique protocol for communication between them. In the end, some measurements of the specific signals were given and the consumption of the whole system was calculated
