S-HELP User Testing


312 UCC staff members participated in an online
survey which
tested the user
interface design principles that have been applied in the S-HELP Decision
Support System. The 312 contributors were entered into a draw to thank them for
taking part in the evaluation. Gemma McCarthy, School of Nursing and
Midwifery
(pictured below with
Michael Gleeson and Silvia Planella of S-HELP)
was
announced as the winner on 23
rd December 2016.


The survey to test decision-making skills under stress is part of a series of
empirical studies to evaluate the effectiveness of incorporating set of design
principles, and was created by Dr Karen Neville (UCC-BIS) and Dr Alexander
Nussbaumer (TuGRAZ).

As described in
the International Symposium “
Digital Scholarly Editions as Interfaces” hosted in September (2016) in Austria:


‘TuGRAZ
elaborated a psychological framework on effective cognitive processing and user
interface design. This framework takes into account psychological factors of
human perception and information processing. Based on this foundation a set of
design principles was derived, which were incorporated in the design and
development of a decision support system for emergency management. The overall
idea of the psychological framework and the general design principles
constitute a generic approach of modelling human-computer interaction and are
therefore considered to have great potential to support the design of user
interfaces and system features in the context of digital libraries and digital
scholarly editions, as well. In detail, these principles are based on aspects
of human information processing, Gestalt psychology of perceptual organisation
(e.g. similarity principle, proximity principle), as well as personal knowledge
and competence modelling. The principles recommend, for example, to visually
group related information, to minimise the need for data transformation by the
user, or to avoid ambiguity in information presentation. These design
principles are meant to guide the design of data-driven user interfaces with
the aim of improving the interaction with system features and/or understanding
of information. Initial empirical studies suggest the effectiveness of
incorporating such principles in interface design on users’ task performance
and subjective perception, and further studies aim at identifying broader
evidence for the usefulness and benefit of this kind of approach for user
interface design and evaluation.’

survey will be reported in the S-HELP Work Package 5 documentation.
