After a long day’s work, we may not pay attention to small things such as turning off the room light before leaving. Bye-5 is an light switch that intuitively reminds people to turn the light off by encouraging a “high-5′ interaction. The adorable hand-shaped look catches your attention, and the soft skin-like touch encourages a “high-5” hit, resulting in room light off, and it also activates a beautiful LED dim light in the “hand” guiding your leaving. A single event sets up a chain of reactions as if a “reward” for your day and for your good behavior that says “Bye, you did a good job!”. The positive feedback is exactly what you need at this moment!
