Deliverable 3.4 Final evaluation of ACCOMPANY computational memory architecture

This document describes the final evaluation of the Accompany computational memory architecture described in deliverables D3.2 and D3.3 and implemented on the Care-O-Bot3®, the companion robot in the ACCOMPANY project. We report on two areas of formative evaluation of the architecture relevant to the aims of Accompany. The first is the evaluation of the robot teaching and learning components and the second is the evaluation of the visual episodic memory component. The design and implementation of the robot teaching components were described in detail in D3.3 and will briefly be summarised in this document, however the design and implementation of the learning components will be described in detail together with their formative evaluation. The visualisation component was also described in D3.3 and will briefly be recapped here together with the results of the formative study. Note that the complete memory architecture has also been formally evaluated as part of the long-term summative studies reported in D6.8.
One of the aims of the ACCOMPANY project is to provide aid and support for elderly people and allow them to reside for longer in their own homes by providing facilities not only for care, but also for companionship. It is envisaged that companionship would be supported by the dual functions of co-learning and re-ablement. This document reports on 1) A recap of the background to this research and a definition of reablement
and co-learning, 2) A brief reminder and explanation of the architecture itself, together with a general description of the environment, the robot and our ontological approach,3) A brief summary of the teaching component and a description of the formative studies and results, 4) A brief summary of the memory visualisation component and a description and results of the formative studies carried out, 5) A detailed description of the new learning components and details of an initial formative evaluation with an informal carer group, 6) A final round-up and discussion of achievements and possible future directions for this research including some preliminary work on sequential action prediction (described in the appendix).
