Lack of dexterity and an aversion to complex procedures can make using a cell phone a pain for many autistics. The Just5 pretty much just makes calls and texts (though surprisingly it has a torch and radio), with a large keypad for ease of use, and amplified sound to drown out background noise that autistics are sensitive to. The talking keypad calls out the digits as they’re dialled, minimising error. A physical switch on the side locks the keypad to prevent accidental dialing. An added bonus is an ’emergency button’ at the back that when depressed for four seconds, auto-dials any number programmed into it (such as the cell phone of an autistic child’s parent). This how the button works (from the company’s website):
For emergency situations, users can preset up to five phone numbers for 911, family, friends, doctors, etc. When users press the emergency SOS button, the phone will text an urgent message (e.g. “I’m having an emergency, please answer”) to these five numbers, then dial them in prioritized order. When dialing, the phone will sound a loud siren to attract the attention of others. Once someone answers a call, the phone automatically switches to loud speaker mode for easier communications. This feature is vital if a user drops the phone after pressing the SOS button.
