Reformulation Strategies Of Repeated References In The Context Of Robot Perception Errors In Situated Dialogue, Niels Schütte, John D. Kelleher, Brian Mac Namee
Reformulation Strategies Of Repeated References In The Context Of Robot Perception Errors In Situated Dialogue, Niels Schütte, John D. Kelleher, Brian Mac Namee
Conference papers
We performed an experiment in which human participants interacted through a natural language dialogue interface with a simulated robot to fulfil a series of object manipulation tasks. We introduced errors into the robot’s perception, and observed the resulting problems in the dialogues and their resolutions. We then introduced different methods for the user to request information about the robot’s understanding of the environment. In this work, we describe the effects that the robot’s perceptual errors and the information request options available to the participant had on the reformulation of the referring expressions the participants used when resolving a unsuccessful reference.
Mobisurround: An Auditory User Interface For Geo-Service Delivery, Keith Gardiner, Charlie Cullen, James Carswell
Mobisurround: An Auditory User Interface For Geo-Service Delivery, Keith Gardiner, Charlie Cullen, James Carswell
Conference papers
This paper describes original research carried out in the area of Location-Based Services (LBS) with an emphasis on Auditory User Interfaces (AUI) for content delivery. Previous work in this area has focused on accurately determining spatial interactions and informing the user mainly by means of the visual modality. mobiSurround is new research that builds upon these principles with a focus on multimodal content delivery and navigation and in particular the development of an AUI. This AUI enables the delivery of rich media content and natural directions using audio. This novel approach provides a hands free method for navigating a space …
A Defeasible Reasoning Framework For Human Mental Workload Representation And Assessment, Luca Longo
A Defeasible Reasoning Framework For Human Mental Workload Representation And Assessment, Luca Longo
Conference papers
Human mental workload (MWL) has gained importance in the last few decades as an important design concept. It is a multifaceted complex construct mainly applied in cognitive sciences and has been defined in many different ways. Although measuring MWL has potential advantages in interaction and interface design, its formalisation as an operational and computational construct has not sufficiently been addressed. This research contributes to the body of knowledge by providing an extensible framework built upon defeasible reasoning, and implemented with argumentation theory (AT), in which MWL can be better defined, measured, analysed, explained and applied in different human–computer interactive contexts. …
Eye-Tracktive: Measuring Attention To Body Parts When Judging Human Emotions, Cathy Ennis, Ludovic Hoyet, Carol O'Sullivan
Eye-Tracktive: Measuring Attention To Body Parts When Judging Human Emotions, Cathy Ennis, Ludovic Hoyet, Carol O'Sullivan
Conference papers
Virtual humans are often endowed with human-like characteristics to make them more appealing and engaging. Motion capture is a reliable way to represent natural motion on such characters, thereby allowing a wide range of animations to be automatically created and replicated. However, interpersonal differences in actors’ performances can be subtle and complex, yet have a strong effect on the human observer. Such effects can be very difficult to express quantitatively or indeed even qualitatively. We investigate two subjective human motion characteristics: attractiveness and distinctiveness. We conduct a perceptual experiment, where participants’ eye movements are tracked while they rate the motions …
On The Relationship Between Perception Of Usability And Subjective Mental Workload Of Web Interfaces, Luca Longo, Pierpaolo Dondio
On The Relationship Between Perception Of Usability And Subjective Mental Workload Of Web Interfaces, Luca Longo, Pierpaolo Dondio
Conference papers
Inspection methods and cheap self-reporting procedures have been significantly employed in the field of Human- Computer Interaction for assessing the usability of interfaces, systems and technologies. However, there is a tendency to overlook aspects related to the context and features of the users during the usability assessment process. This research introduces the concept of mental workload as an aid to enhance usability measurement. A user-study has been designed and executed in the context of human-web interaction. The aim was to investigate the relationship between the perception of usability of three popular web-sites, and the mental workload imposed by a set …

Designing Medical Interactive Systems Via Assessment Of Human Mental Workload, Luca Longo
Designing Medical Interactive Systems Via Assessment Of Human Mental Workload, Luca Longo
Conference papers
In clinical settings, Human-computer systems need to be designed in a way that medical errors are reduced and patient care is enhanced. Inspection methods are usually employed in HCI to assess usability of interactive systems. However, they do not consider the state of the operator while executing a task, the surrounding environment and the task demands. It is argued that assessing performance of operators is fundamental for designing optimal systems with which healthcare can be effectively delivered. The aim of our solution is to assess performance of operators employing the notion of Mental Workload (MWL) this being a construct believed …
