Ryst

University Project, Interaction Design, Haptic Feedback

Ryst is a redesign of a navigation system for autonomous driving. It allows for easy route alterations based on points of interest gathered from the user’s previously visited locations and social media interests. Besides this it is also an investigation in the way haptics can further enhance the dialog between the car and the user through touch screen based interfaces. Something that will become increasingly important as car-control becomes more and more indirect. This loss of direct control and contact with the car will put extra strain on the interaction points that are still left in the autonomous vehicle.

The GUI was build in Unity 3D and uses serial communication to drive the Arduino Mega that controls the haptic actuators. The style of the interface is purposefully minimalistic to keep the user focused on the haptic conversation they have with the device.

The haptic actuators in the device consist of 2 servos pulling down on a spring system. This allows the whole screen to move up and down as well as tilting back and forth. Behind the screen is a plate of 4 vibration motors allowing for more subtle haptic interactions. These 2 different systems allow Ryst to mix between macro and micro haptics.
