Design Challenge

Interaction Situation

Humans and robots are moving in the same space. The robot changes the direction of its route by turning on the spot and makes this change of direction visible to the user.

Communication
Goal

“I am turning on spot.”

Design Solution

Solution

Let the robot express its direction of rotation and speed with the help of a dynamically rotating light signal. Recommended color: warm yellow, brightness: good visibility in changing light conditions, rotation speed of the light adjusted to the speed of rotation.

Rationale

Vehicles indicate a change of direction using lights, such as the indicators on both sides of the vehicle or the reversing light. Moving elements direct our attention. This is known as “attention to movement”. When something moves, our eyes and our focus automatically follow this movement. LED strips, which are designed as running lights, are used in various devices and applications to indicate directions.
