Designing Accessible Software for the Electronic Abacus

Electronic Abacus (e-Abacus) using FPGA Altera DE2 Board

“…This capability enables the Indian Abacus to be used in primary and secondary abacus competition, thus emphasized as educational tools. Electronic abacus proposed by Alison Barker [2], is equipped with electronic sensors which detect the abacus bead position and transmit the data through USB and displayed on the computer screen. The additional features of audible capabilities and magnified text enable this prototype to be used by visually impaired personnel and normal person as well.…”
