Hearing
In 2005, the World Health Organization estimated that some 278 million people worldwide had moderate to profound hearing loss. For these people using a telephone of any type can be a real challenge. Most mobile phones offer a range of features that can certainly make a noticeable difference to those with hearing difficulties, including:
- A range of visual alerts to notify the user of incoming calls/messages
- Adjustable volume control
- Display of missed, received or dialed calls through call logs
- Visual or tactile indicators showing what's been pressed on the keypad, and visual display of text
- Text based messaging options
