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)!

Decrease depression, Increase physical function and balance ! (Rosenberg et al., 2010, Jung et al.,

Background Exergames and training!
Seniors can benefit most from ‘exergames (Peng 2011) !

Data collection
Results Exergames usability !!
ANOVA p = 0.007 !
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 !

Aim
Design a new and simplified exergame concept for senior citizens, which focuses on physical activity in general, and balance and muscle strength in particular.!

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 !
• Paper prototypes!
