Kinetic compass task list:
Establish mechanism(s) to indicate to the user the current direction without relying on sight or sound, and instead the sensation of touch to give live updates of user surroundings.
See which of the mechanisms established before provides the best balance between size, efficiency, and reliability
Establish how the compass will be used by a prospective user, and if it should be mounted to the user
Design the compass and it’s internal components based on the previous point.
Internal testing to make sure the functionality works properly when integrated
In-field testing to ensure that blind and deaf people are able to use the compass without issue.
Design goals:
Provide a sense of direction for the user, and be accurate an overwhelming majority of the time
Be small and compact, ideally able to be on the user at all times without being disruptive to their day to day activities
Direction indication mechanism shall not rely on sight and/or sound senses, in order to be accessible to folks who are both blind and deaf, and should also be not too disruptive.
Design specifications:
Compass shall be no larger than 90mm in diameter, and ideally should be about 15-30mm
Compass shall have a lifespan of 10 years at minimum, with an ideal lifespan of 20-30 years.
Compass shall be water resistant such that exposure to water for 5-15 minutes (an example would be if the user is in rainy weather) doesn’t cause any major damage and doesn’t compromise functionality.
Compass shall not require servicing until at least the minimum lifespan has elapsed.
