Abstract

This paper summarizes the first nine months of progress on my Ph.D. project. The research focus of the project is on investigating microinteractions. a sub-topic of HCI and gesture research. The project will develop a framework for applications that use microgestures to support everyday tasks through invisible and context-aware appearing interface layers underneath objectgrasping hands. In an expert study that has been accepted as a full paper at INTERACT 2011, I explore the motor limitations and opportunities of microgestures while grasping objects and valued manual dual-task scenarios by walking through three tasks that involve grasping objects. The outcome of the study is a generic microgesture set for different grasp types and a collection of parameters that have a relevant effect on the choice of the grasping tasks. A further user study in progress is investigating the effect of grasped objects, such as handheld devices, on the feasibility of performing microgestures. Users are asked to perform finger-tip and drags on the front and/or back of a handheld device. The device is two-sided and touch-sensitive, it is made by stacking 2 pads together in a sandwich-like prototype. This allows tracking users' finger gestures through a camera as well as through front and touch screens. The outcome of the two mentioned studies will describe a design space for out-of-agrasp microgestures. At the INTERACT doctoral consortium I aim to present this design space and discuss how this can serve as a basis for developing a framework of out-of-grasp microinteractions that are subtasks of grasping tasks. The microinteractions will be developed to support the grasp tasks with regard to their perceived ergonomic and hedonic qualities.
