Applying New Touchscreen Cover Model to Facilitate Communication by Blind Individuals on Mobile Devices

Résumé

According to a World Health Organization (WHO) fact sheet on blindness and vision impairment, the current estimate of global population of visually impaired individuals is at least 2.2 billion and the number is continuously increasing [1]. From the other side, the expected number of mobile device users worldwide is projected to reach seven billion by the year 2025 [2]. Based on these statistics, it is considered highly beneficial to introduce blind community to mobile technology, as it facilitate their communication with others. In overall, this technology has the potential to compensate for their loss of vision sensory. Existing communication methods for blind individuals imply several limitations, including the challenge of localizing object positions on touchscreen, as the works presented in [3, 4, 5, 6], entailing different types of gestures with multiple fingers to encode Braille characters as the methods proposed in [7, 8, 9, 10, 11] ,and the high cost associated with attaching terminal units, hardware components, sensors, and actuators to augment, for instance, the frameworks proposed in [12, 13, 14] [15, 16, 17, 18]. To overcome these limitations, this research introduces an innovative solution for tactile-based interface. A framework was developed to enable blind impairments to input Braille-based characters. This framework integrates two main components: a touchscreen grid cover and an Android app interface, and it mainly built on the haptic capabilities
