Contextual Challenges
Helping people with disabilities
Blindness
Electronic device to help blind people learn braille
Using prerecorded voices and sounds to help blind people navigate a braille keyboard ( e.g. when a key is pressed the corresponding letter is said)
Proximity sensor on a walking stick.
having a walking stick with a proximity sensor that detects how close a blind person is to an obstacle., if too close to an object an output is sent out either in the form of a sound or a vibration.
Deafness
A wireless communication device that converts sound to light.
Connects to a doorbell, and when bell is pressed a small light is activated alerting the deaf person.
A vibration to alert the deaf person of a sound.

A solar powered battery charger
Helpful for developing countries that live in hot, sunny climate.
Aiding people who do not have access to new resources such as batteries and this would help them reuse things that they already have.
Doesn't require mains electricity, some developing countries may not have reliable access to mains electricity.
A dynamo that acts as a temporary generator
Could use gravitational potential energy to rotate the dynamo.
Using GPE means less effort from humans, could be achieved by attaching a weight.
A renewable source of energy, although temporary, can be used to power small appliances
Could have a capacitor attached to store charge for later use.
Motorised fan that is activated by solar power
Encouraging a healthy lifestyle
