The effectiveness of software interface design is a lot of the times tied to the user of the software. In particular, it is tied to how users comprehend the spatial stimuli presented to them through the software interface (spatial information encoding). Thus, the goal of the research is to understand the aspects of different levels of spatial ability on a spatial software interface for creating a theoretical structure of spatial ability on a simple task as a stepping stone to understand a more complex demanding task. Why is this important? The importance of knowing the different spatial ability aspect relates to how one can design software interfaces to suit different levels of spatial ability.;To examine the impact of spatial ability on using user interfaces, we developed a set of user interfaces that required the user to interpret an instruction and choose the matching buttons. In total three interfaces were developed ranging from simply matching colors to an interface loosely based on the address canvassing task used by the Census Bureau to identify the correct location of housing units. A cognitive model was developed for the interfaces that incorporated spatial ability. The model was implemented using ACT/R and evaluated against user studies involving 63 participants.
