Abstract

A tactile visual indicator and methods, apparatuses, and computer program products for controlling a tactile visual indicator are provided. Embodiments include a light source; an electromagnetically inductive wound coil; and a light pipe coupled to a ferromagnetic-metal jacket surrounding the outside of the light pipe. The ferromagnetic-metal jacket is within the wound coil and one end of the light pipe is provided to the light source. The light pipe and the ferromagnetic-metal jacket are configured to move within the wound coil in response to the coil receiving power. Light shining through the light pipe from the light source provides a visual indication of a status and the movement of the light pipe and jacket within the wound coil provides a tactile indication of the status via contact with a user.
