The Tactile Sense as a Correlate to Effective Mobility of Persons with Visual Impairment in the North West South West and West Regions of Cameroon

Abstract

Visual impairment is a condition where the retina or the visual centre in the inner brain does not function normally and therefore cannot transmit light stimuli to the brain (Avoke 2004). The Centers for Disease Control and Prevention (CDC) (2014), postulated that; visual impairment is the functional limitation of the eyes or the vision system which could be manifested through: loss of visual acuity and inability of the person to see objects as clearly as a healthy person; loss of visual field - inability of an individual to see as wide as possible an area like the average person without moving the eyes or turning the head. From an educational perspective , , visual impairment is a condition whereby the vision of one is limited to such an extent that his/her effectiveness in coping maximally with normal classroom teaching and learning is adversely affected. This therefore, calls for accommodation or adaptation and modification for optimal community and classroom functioning (Jurmang, 2016; Pierangelo and Giuliani, 2007).
