Bux is a controller for Philips Hue Light to interact with the lighting ambiance at home in an effortless way. Turning on or off the light is as simple as tapping the stick or the ball. The four corners represent four light modes and the center of the cross pattern is a default scene, which can be personalized by the user. You can choose light mode by simply moving the stick to that direction. The brightness can be adjusted by sliding the ball up and down. Bux also supports detailed control in the app, where the physical interface will automatically change with your adjustment.
