Development of a cursor for persons with low vision

Abstract

Objects such as windows, icons, menus, and pointers are being smaller and closer on devices display. Small and closely packed object requires more time and efforts in acquisition of target object persons with low vision. Traditional magnifier and cursor technologies are increasing recognition rate with magnification, color contrast, big-sized cursor and separation of the object. But, in the case of low vision, this traditional magnifiers and cursors are not enough to acquire target objects easily. In this paper, we propose a CPLV (cursor for persons with low vision). Basically, CPLV supports magnification, color contrast, and bigsized cursor for persons with low vision. Furthemore, it supports constraint of cursor movement, reduce of hand fatigue, and voice service.
