    Strategies for Human‐Driven Robot Comprehension of Spatial Descriptions by Older Adults in a Robot Fetch Task
    with Marjorie Skubic, Jared Miller, Zhiyu Huo, and Tatiana Alexenko
    Topics in Cognitive Science 6 (3): 513-533. 2014.
    This contribution presents a corpus of spatial descriptions and describes the development of a human-driven spatial language robot system for their comprehension. The domain of application is an eldercare setting in which an assistive robot is asked to “fetch” an object for an elderly resident based on a natural language spatial description given by the resident. In Part One, we describe a corpus of naturally occurring descriptions elicited from a group of older adults within a virtual 3D home t…Read more

    Mechanisms of Reference Frame Selection in Spatial Term Use: Computational and Empirical Studies
    with Holger Schultheis
    Cognitive Science 41 (2): 276-325. 2017.
    Previous studies have shown that multiple reference frames are available and compete for selection during the use of spatial terms such as “above.” However, the mechanisms that underlie the selection process are poorly understood. In the current paper we present two experiments and a comparison of three computational models of selection to shed further light on the nature of reference frame selection. The three models are drawn from different areas of human cognition, and we assess whether they …Read more
