I am a Human-Computer Interaction researcher at Aarhus University. My research focuses on development and application of data-driven methods for the HCI tasks. Novel interaction methods such as full-body, gestural or touch interaction offer immense design space. It is impossible to compare experimentally all design alternatives and pure intuition can be misleading. I want to improve interaction methods by capturing the whole design space and formalizing its performance and ergonomics properties in a mathematical model. Then optimal interfaces can be identified computationally. I adopt optical motion capture and biomechanical simulation besides standard performance measurement methods for the HCI experiments to achieve the goal.
