A Study Looking for User’s Mental Model to Achieve Intuitive Typing

Introduction

A laptop with dual screens is a trend for the coming future. It means typing on an LCD screen displaying dynamic content instead of a fixed physical keyboard is an emergent design possibility. However, the current approach only showing a static keyboard graphically on the screen wastes the potential of a sensible and displayable touch screen. In this research, we are going to design an “Adaptive Typing” mechanism that actively detects user’s hand palm resting on the screen and automatically predicts key locations. This mechanism also provides minimum visual clues to assist novice users. In order to realize this idea, we design an experimental desk to collect and observe users’ mental models and hand ergonomics while typing. As shown in the picture, the upper camera collects data about keys and fingers; the lower camera collects data of hand palms through a transparent part with which a conventional keyboard and a touch pad embedded in. We believe that by overlapping image data of upper and lower cameras, the hidden relationships between hand palm and typing can be further revealed.

Introduction

Adaptive Mouse (AM) consists of a smart material which is deformable and is capable of recognizing the deformation. The deformation provides perfect and comfortable ergonomic shape for users’ diverse hand gestures. The smart material itself could also dynamically activate any areas at will for conventional buttons and scroll wheel. The prediction of active areas is based on the recognition results of users’ hand gestures. Working with AM, all users have to do is to hold it with his/her comfortable and preferred hand gestures, then acting their fore and middle fingers intuitively will always correctly trigger related button functions. Users can also freely move the mouse and always get cursor feedbacks accurately.

Compensating for the disappeared formal implication by functional adaptability

Introduction

Adaptive Camera is discovering the idea that whether it is possible to compensate the elimination of formal implications for flexible operation by providing functional adaptability. In detail, I am going to create a digital camera which has no elements of implications at all such as a rigid shutter button and a boxlike appearance. However, with functional adaptability users could still use this camera intuitive as normal. The button of this camera will be automatically assigned and the orientation of the camera scene will be calibrated as well based on how users hold it.

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.
