Introduction

After studying 12 user’s behaviors of using a microwave oven through Contexual Inquiry Method, we finally figure out that a touch free interface is needed due to oily hands of users which always interrupt the cooking process. For clean and safty reasons, we create this touch free interface for users to test again. After comparing with previous ordinary microwave door, our touch free door does improve the usability of a microwave oven.
