One PhD student position in computer science with focus on socially intelligent systems for person-tailored digital coaching
(deadline 2017-11-03):
https://umu.mynetworkglobal.com/en/what:job/jobID:170497/

Interested applicants are encouraged to apply for both positions.

Both positions are part of our research addressing the fundamental challenge how intelligent autonomous agents may collaborate with humans in decision making tasks to achieve goals, and in making prioritizations among potentially conflicting goals, needs, motivations, preferences and choices of actions, e.g. in medical situations where  healthcare professionals diagnose or select treatment methods. This is also highly important in situations where a person aims to change unhealthy behaviour, or needs to take action in order to reduce risk in work situations.

To provide socially intelligent systems that humans can trust enough to collaborate with, algorithms for explaining automated learning, reasoning, and values of arguments and decision outcomes will be developed. Artificial intelligence-based methods for user modelling, user adaptation, and for the system to act in a socially acceptable way tailored to a situation will also be developed, partly by formalising theories about human behaviour. Methods that handle uncertain and incomplete information, as well as different types of values, norms, or utilities in such situations will be explored. Furthermore, new interaction designs and user interfaces for efficiently creating a shared understanding and agreements between system and human will be explored.

The positions will be part of research projects where behavior change systems will be developed and applied to improve health. Research will be conducted in a multi-professional team, and the development of solutions in close collaboration with end users and healthcare professionals.

Title:
Supporting Human Activity Performance Using Argumentation-Based Technology

Abstract:

“The aim for the research presented in this thesis is to develop theories, methods and technology which can detect, represent and evaluate purposeful human activity based on information, which is inconsistent, incomplete and which includes information about an individual’s needs, goals and motives.
The purpose is to provide instruments to the fields of assistive technology and ambient assisted living, which have the potentials to advance the treatment of semantic information for the purpose of making decisions and reasoning about complex human activity in daily life. Furthermore, based on sound interpretations of activity and evaluation of activity performance, tailored recommendations can be provided to the individual.

This is achieved by integrating theoretical models of human activity with formal argumentation theory, and in this way create a model for representing the knowledge. Also based on the activity-theoretical models of human activity and argumentation, a computational model for common-sense reasoning was built based on the notion of fragments of activity. Moreover, a calculus model for evaluating activity performance considering the so called activity fragments was developed. These theoretical models were forming a base for implementing an argument-based reasoner engine, which manages incomplete and inconsistent information.

These results were implemented in a prototype system designed for aiding an individual in improving health in daily life, for the purpose of testing the theories and methodologies with potential users. Information obtained by the sensors of a mobile phone and by assessments done by the individual regarding priorities, goals and motives were used in the analysis. Preliminary results are fed into further development, and future work includes user studies over a longer period of time. Furthermore, assistive technology for monitoring human activities in different contexts such as mining and construction industries are also being developed and tested.

Future work includes also the development of methods for reasoning about activities based on data-stream sources, and taking into account that human needs, goals and motives vary over time. Moreover, methods for automatic configuration of intelligent collaborative agents and for fusing of heterogeneous data sources for providing tailored services will also be developed and evaluated in the ambient assisted living context. ”

Children-Robot-Dog Interaction, a different kind of Summer Job

Posted on | July 22, 2013 | Comments Off on Children-Robot-Dog Interaction, a different kind of Summer Job

Agnes Karbin, Moa Lindgren and Mikaela Rosendahl have spent part of their summer vacation time working on knowledge enginering, interaction design, robot programming and evaluating their smart applications with children and dogs.

 

 

 

They used ACKTUS as knowlege modeling tool for creating an application for children aged 6-10 years old, which adjusted itself to the knowledge and performance of the child. To make the teaching moment more exciting, they also put the NAO robot Neja in the role of the teacher. When Neja asked questions, the children managed to answer correctly, and as a reward, the robot showed how she could throw a ball to Bosse the Dog. Even more fun it became when the children could help Neja when the dog did not put the ball into the hand of Neja.

Agnes, Moa and Mikaela have been studying different gymnasium programmes, media, social science and natural science, and none of them had a thought on programming or dog-robot interaction for summer job. The opportunity to work at the Department of Computing Science came through the reasearch projects ACKTUS, As-A-Pal and Safe Steps, which aim at developing smart applications for daily living. The new pilot project ACKTUS-skola, was an experiment on whether ACKTUS could be used for knowledge engineering and interaction design for a domain other than health care. The young knowledge workers developed a prototype application for the purpose, and tested their result. Next step is to involve pedagogic experts and create methods for mediating educational dialogues with the NAO Neja.
