One of Apple’s famous minimalist design principles is to get rid of buttons whenever possible. With touchscreen devices like the iPhone and iPad, almost all of the buttons appear when needed on the screen. But what about Macbooks with aluminum casings? A new patent application titled “Disappearing Button or Slider” shows that Apple is at least thinking about how to bring elements of touch computing to all devices by replacing buttons and other controls with capacitive controls which appear only when needed.
The patent describes a way to create backlit micro-perforated holes on the aluminum casing of a MacBook or other device which could be used for buttons on the lid when the laptop is closed or below the keyboard when it is open. The buttons could serve as simple displays for WiFi signal or battery strength, control playlists and volume for iTunes songs or movies, or even replace the trackpad.
