Application

Design takeaway

Design systems that actively communicate machine status and user feedback through intuitive visual representations of biosignals, enabling a more collaborative and informed user experience.

How to apply

When designing control systems or interactive products, explore how user biosignals (like muscle activity or brainwaves) can be captured, processed, and visually presented back to the user to inform their actions or provide status updates.

Project actions

  • 01When designing an interface, think about how you can show the user what the system is 'seeing' from their input, especially if that input is biological.
  • 02Consider how visual cues can help the user understand the machine's state and their own influence on it.
