Human-computer interface system

A system comprising:

• a substrate comprising a first set of electrodes;
• a cover layer:
• defining a continuous touch surface extending over the substrate;
• comprising a first active touch region arranged over the first set of electrodes;
• and
• comprising a second inactive touch region offset from the first set of electrodes;
• a haptic actuator comprising:
• a multi-layer inductor;
• and
• a magnetic element defining a first polarity facing the multi-layer inductor;
• a set of spacer elements:
• arranged under the first active touch region of the cover layer;
• and
• configured to compress responsive to application of the first touch input on the first active touch region to increase magnetic coupling at the first set of electrodes;
• and
• a controller configured to, in response to detecting the first touch input at the first active touch region on the continuous touch surface, trigger the haptic actuator to generate oscillations across the first active touch region of the cover layer.

A system comprising:

• a substrate comprising a set of electrodes;
• a haptic actuator comprising:
• a multi-layer inductor;
• and
• a magnetic element facing the multi-layer inductor;
• a chassis:
• arranged under the substrate;
• and
• comprising an inactive support surface;
• and
• comprising a cavity inset below the inactive support surface;
• a cover layer:
• defining a continuous touch surface extending over the inactive support surface and the cavity of the chassis;
• comprising a first active touch region arranged over the first set of electrodes;
• comprising a first inactive touch region offset from the first set of electrodes;
• and
• comprising a transition region interposed between the first inactive support surface and a lateral edge of the first active touch region.
