Abstract:
The hands are our primary means to manipulate the environment. Due to the large number of degrees of freedom and tremendous connection to neural system, hands can perform skilled movements and are a common input channel in human-computer interfaces. Mobile contexts, however, introduce immense number of physiological and cognitive tasks that affect manual input performance. The input performance can be improved by optimizing the physical form of the mobile device and the interface's interactions to support the available hand functions.
My PhD research presents tools for design and evaluation of mobile interfaces. The work investigates the effects of user interface design to manual mobile input performance, focusing on how the design can take the maximum advantage of the available functions and capacity of the human hand. In this talk I will introduce two interface evaluation tests and present a model for predicting the functional area of the thumb on mobile touchscreen surfaces.
