KOʻZI OJIZ TALABALAR UCHUN MATEMATIK FORMULALAR, JADVALLAR VA GRAFIKLARNI AVTOMATIK AUDIO VA BRAYL TASVIRIGA OʻGIRUVCHI DASTURIY KOMPLEKS YARATISH
Abstract
Maqolada koʻzi ojiz talabalarning matematik materiallarni mustaqil oʻzlashtirishiga toʻsqinlik qiluvchi asosiy omil - formulalar, jadvallar va grafiklarning koʻrib idrok etishga moʻljallangan ikki oʻlchovli tuzilishi tahlil qilinadi. Ushbu muammoni hal etish uchun bunday obyektlarni avtomatik ravishda oʻzbek tilidagi audio va Brayl shakliga oʻgiruvchi dasturiy kompleks taklif etiladi. Kompleks beshta moduldan iborat: kirish, semantik tahlil, audio generatsiya, Brayl generatsiyasi va chiqarish. Formula abstrakt sintaktik daraxtga (AST) aylantiriladi, soʻngra daraxtni rekursiv aylanib chiqish orqali prosodik belgilarga ega nutq matni va Nemeth kodidagi Brayl yozuvi hosil qilinadi. Jadvallar ustun sarlavhalari saqlangan holda navigatsiya qilinadigan audio shaklga va chiziqli Brayl formatiga, funksiya grafiklari esa logarifmik chastota akslantirishiga asoslangan sonifikatsiyaga hamda 8 nuqtali taktil rastrga oʻgiriladi. 350 ta obyektdan iborat test toʻplamida audio shaklga oʻgirish aniqligi 96,3% ni, Brayl yozuviga oʻgirish aniqligi 94,3% ni tashkil etdi. 12 nafar koʻzi ojiz talaba ishtirokidagi sinovda grafik xossalarini aniqlash boʻyicha toʻgʻri javoblar ulushi 41,7% dan 85,0% gacha oshdi.Keywords
