Background

Aged > 60 by 2050 : Double (22%)! (UN World population ageing 2009) !

Fall related injuries:!35% > 65 : One or more fall a year !45% > 80 : One or more fall a year !

(Rosenberg et al., 2010, Jung et al., 2009) !

Aging and fall risk !

Background

Aging population: Aged 60 and older set to double (more than 22%) of overall population!

Exergame: Video games controlled by physical movements!

Outcome: Decrease depression, Increase physical function and balance !

! (Rosenberg et al., 2010, Jung et al., 2009, Schoene et al, 2013) !

Generally exergames are not designed for Seniors!

Background

User Experience (UX): “the extent to which the product can be used by the specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use” (ISO 9241)!

Young area of research: Exergames RCTs !

( Randomized Controlled Trial)!

Background Exergames and training!

Seniors can benefit most from ‘exergames (Peng 2011) !

Results Card - Ranking !!

p= 0.26 !

Results Important factors of user experience !! TAM Constructs Related Issues

Performance Expectancy + improve balance and keep in shape + cognitive challenge + music

Effort Expectancy + game narrative - perform correct movements

Social Influence + No social influence

Facilitating Conditions - Small space

Results Important factors of user experience !! Emergent Constructs Related Issues

Social Experience + Playing with grandchildren + Playing with seniors + Playing alone

Safety + Not concerned (Healthy seniors)

Setup - Support to setup exergame system

Progression + Progression through game difficulty

Localization - Language

Conclusion !!

Senior-centred exergame demonstrate better usability and acceptability !

Relating game narrative to real life !

Local language interface for seniors !

Need to provide feedback for correct movements !

Validity of Study !!

Participants relatively healthy; recruited from exercise classes for seniors!

Fairly high familiarity with technology !

Only 3 games were tested !

No explicit constructs to measure intrinsic motivations !

Evaluation

•  Qualitative assessment of observations !

•  Coding of interviews and feedback!

•  Game flow model !

Workshop 1

•  7 participants !

•  Both multi-player and single-player !

•  Four commercial games: 1, 2) Kinect Sports Season Two: tennis and skiing, 3) Fruit Ninja, 4) Your Shape Fitness Evolved 2012: Aging with Grace!

•  Questionnaire, observation, and group discussion!

Workshop 1 - Results •  Information Display: Simple, very simple!

•  Clear Outcome: Why are we doing this!

•  Progress and Learning: Are we doing it right?!

•  Appropriate Music!

•  Suggestions: Real-life activities: wood chopping, picking apples, walk in nature, biathlon !

Implementation of Prototype

Game concept: Out in nature!

Prototype: Look and feel!

Type: High fidelity !

«Out in nature»

«Out in nature»

a) Jump from rock to rock b) walk over the log lying across the path !

c) duck under the branch d) get over the lake by rowing boat !

e) balance on the log to get over river f) walk on the rock laying on the path !

Workshop 2 •  Same participants!

•  Computer and Projector !
