New publication: Reflections on design workshops with older adults for touchscreen mobile text entry

On touchscreen devices such as smartphones and tablets, text entry remains key to many tasks and is an important factor in the usability of such devices. The physical and cognitive issues associated with ageing can make the known problems of text entry particularly acute for older adults. Poor usability can present a significant problem for older adults where accessing services and social activities are concerned, both of which have implications for exclusion. In a study of mobile text entry where we aimed to develop novel keyboard layouts to address the particular requirements of this group of users we employed a variety of participatory design techniques. We report on our experiences from employing these methods and the methodological implications for further research in this area.

New publication: Text Input on a Smart Watch

Smart-watches provide users with access to many applications on smartphones direct from their wrists, without the need to touch their smartphone. While applications such as email, messaging, calendar and social networking provide views on the watch, there is normally no text entry method so users cannot reply on the same device. Here we introduce our interaction design for smartwatch text entry, an optimised alphabetic layout and present a lab evaluation of an implemented prototype using the OpenAdaptxt engine on a Sony SmartWatch 2. While raising some problems, the feedback from our participants indicates that reasonable quality and speed is achievable on a smart-watch and encourages our future work.

"Designing Human-Centred Pervasive Systems" - Summer School in cooperation with BEST (University of Patras Chapter)

BEST Patras Summer Course 2014 is taking place in Patras, Greece on 13-23th of July. Together with the students running the local BEST chapter, we organised this summer course involving 24 students from all over Europe. The purpose was to provide an introduction to Ubiquitous Computing and teach the students the process of converting an idea for a mobile app, to a design that can be tested with real participants.

New publication: Shake ‘n’ Tap: A Gesture Enhanced Keyboard for Older Adults

The need for text entry on smartphones and other touch-screen devices is key for many tasks and also a key factor in the usability of these devices. Physical and cognitive issues associated with age can aggravate the task of text entry for older adults. Technological exclusion due to low usability can present a significant problem both for social and ongoing business-related tasks with older adults. This paper investigates a new touch-screen keyboard design for older adults that combines the familiar QWERTY keyboard layout with physical gesture. User studies with older adults showed our keyboard reduced miss-taps, but was slower to use, and raised issues for further research.

New publication: A Mobile Shopping Assistant to Support Product Domesticity in Consumer Decisions

In this paper we propose and develop a mobile persuasive application to raise user's interest in specific products, by providing information about each product, focusing on the production country and the origin of the company that produces it. During shopping, the user receives information about each product by optically scanning product barcodes with a mobile device. Recommendations for similar products based on product origin are also provided. In an exploratory evaluation, users indicated that the application was found to be easy to use and was rated useful. Moreover, our experimental results show that the proposed system can significantly affect the decision making process of the users.
