Sensor walk
September 16th, 2009 | Published in Physical Computing
I thought of sensors during this walk as any physical, non-human thing that provides a response to an action.
A Walk…Don’t walk signal.
Once a time interval has passed, the light changes to Walk [On, 1]. An added variable is the push button to initiate the change.
A simple sensor is the ol’ newspaper dispenser (what are these called?).
Upon receiving the correctly sized coin, the door becomes operable and openable.
An apartment buzzer. This one is two sensors: A buzz alerts the apartment inhabitant, the inhabitant responds by pressing the Door button, which unlocks the main door lock.
I also came across an ATM, the swipe card to get to the bank after hours, and a garage door.
Reading reference: Would these be considered interactions? Low-level, at best, to Crawford.
