Shape Shifting Controllers

An in-car touch controller that can change shape to communicate with the driver intuitively, and guide the interaction almost subconsciously. This reduces information overload and lowers driver distraction by complementing vision and hearing based HMI channels.

For this project I worked on ideation, patenting, UX design, feedback methodologies and implementation mechanisms. I also led and directly managed the company that created the first official prototype and the company that created the official video.

This was a really interesting project with some deep HCI aspects such as the idea of "load balancing" the human senses. In the vehicle, the driver's visual channel is already occupied for the primary task of scanning the road and maintaining the vehicle direction and safety. That's the best and safest use for the driver's eyes.

The auditory channel is also often occupied by listening to music, podcasts or audiobooks, or in a conversation with a passenger. The auditory channel is also already utilized for emergency notifications from the vehicle therefore not the best channel to overcrowd.

The tactile sense however is often underutilized in the vehicle. Some modifications to the HMI interface can allow the Infotainment controller and the steering wheel to change shape, surface texture or stiffness in order to communicate the current menu position in the infotainment system, suggest the best interaction method with the current screen, orient the driver and provide feedbacks without using visual or auditory signals.

Granted Patent on Haptic language for shape-shifting steering wheel

This polished UX prototype demonstrates how dynamic shapes enhance infotainment system interactions. Showcased globally, it highlights the potential of shape-shifting rotary controllers in automotive design.

Company: Harman International
Team: Future Experience Team
Location: Palo Alto, CA
Year: 2014-2015

This concept video from late 2015 explores a variety of shape-shifting interfaces, including shape-altering rotary controllers, thickness-adjusting steering wheels, and surface-changing hand rests. These interfaces are intentionally hands-free and rely on tactile interaction, avoiding additional visual or auditory demands on the driver to reduce sensory overload.

Several concepts presented in the video have since been developed into functional prototypes, with some approaching production-ready status. All innovations shown are safeguarded by patents.

This innovative prototype combines input and output functionality, dynamically adjusting its shape as the user rotates the knob. Powered by six servos controlling 12 smooth, touch-safe blades, it offers a tactile and intuitive experience, ideal for eye-free manipulation of an entertainment system while driving.

This high-fidelity prototype uses 8 actuators in the steering column, offering dynamic interactions, like countdowns for exits or collision warnings, making messages intuitive and immediate. While not a finalized product design, this prototype demonstrates innovative ways to enhance driver awareness and earned a comprehensive patent.
