The elevator brings convenience to our life but reduces chance of walking at the same time. Since numerous studies indicated the positive impact of walking on human healthy, we propose an idea to encourage people to do more stair-walking in daily life and also energy saving.
People walk stairs will be rewarded by tagging card at middle of stairway, where the machine located. The reward is limited twice per day and the time interval should be longer than one hour.
