Technology to Provide: Playware Personalisation • Adapt to personal level Inclusiveness • Different physical abilities • Different cognitive abilities • Different cultures • Different ages Social interaction • Technology as mediator • Activities of daily living - through modularity Center for Playware Professor Henrik Hautop Lund, hhl@playware.dtu.dk
Playware Playware Robotic technology inspiration may help and inspire • creating interactions • of many different kinds • in the physical environment • can motivate specific actions • because of immediate feedback • Motivate through play • Play is a free and voluntary activity HM Queen Margrethe II of Denmark Center for Playware Professor Henrik Hautop Lund, hhl@playware.dtu.dk
Modular Technology for Playful Physical Interaction Playware Modularity: Anybody, Anywhere, Anytime • Physical construction and interactivity • Setup within 1 minute • Automatic structure detection • Adjustable levels, different activities Center for Playware Professor Henrik Hautop Lund, hhl@playware.dtu.dk
Building the “Body” • Flexibility through adaptivity Playware • Adaptivity: also by physical construction Center for Playware Professor Henrik Hautop Lund, hhl@playware.dtu.dk
Clinical tests in hospitals Cardiac patients, typically 55-85 years old Playware Teams of 20 patients for 3 months periods Games demands an average heart rate: • 75% of the maximum heart rate with Colour race on floor • 86% of the maximum heart rate with Stepper Estimated maximum heart rate: 220 – age. “When doing rehabilitation not everything is as much fun. Then it is nice to have a little competition. When having gone through a heart attack it is not always desired to go down to the gym and exercise. There has to be something to “spice it up”, and I think that the tiles makes this possible”.

Therapists questionnaire 10 out of 10 therapists in Denmark responded: Playware • in future they will continue to use modular tiles for their particular patients (training balancing, coordination, cognition, attention, endurance, physical fitness) 9 out of 10 therapists in Denmark responded that they experienced the modular tiles to: • be fun for patients • be motivational for patients • be a good supplement to other equipment • have challenged the patients’ balance • have challenged the patients’ cognitive level • be flexible to the patients’ different physical and cognitive levels www.playware.dk Professor Henrik Hautop Lund hhl@playware.dtu.dk
But do such kind of Exergames really have a significant effect? Playware Should we promote such Exergames to a wider population? Are they effective? www.playware.dk Professor Henrik Hautop Lund hhl@playware.dtu.dk
Exergames Effect (-- elderly falls) Exergames (screen focused, off-the-shelf): Playware • Nintendo Wii, Kinect, DDR, EyeToys, etc. Energy expenditure (Peng et al 2011 – meta-analysis) But despite energy expenditure, no substantial physical effects among elderly women playing Wii (Wollersheim et al. 2010) Similar trends of no or limited effect in recognized tests of fitness, mobility, agility, balancing (Franco 2012; Nitz 2010) • Exceptions with specific patient groups (e.g. hemiparetic patients) More scientific effect studies are needed (Lange et al. 2010; Taylor et al. 2012; Wiemeyer & Kliem 2012) www.playware.dk Professor Henrik Hautop Lund hhl@playware.dtu.dk
“Traditional” Training -- Effect Exercise helps preventing falls in older adults (Gillespie et al. 2003; Playware Sherrington et al. 2008) Criticized: often recruting subjects of too low risk of falling Need to target those who benefit the most: older people with strength and balance deficit, women aged 80+, and those aged 70+ with at least one fall risk factor (Barnett et al., 2003) Often only improvements on a few factors • Strength training: improve strength – not balance • Tai Chi: improve balance – not strength High dosage needed (Lord et al., 1995, 1996). Review and meta-analysis suggests high dose of training: >50 hours (Sherrington et al., 2008) >25 training sessions (Araya-Ramirez et al. 2010) www.playware.dk Professor Henrik Hautop Lund hhl@playware.dtu.dk
Effect of Short-term Exergaming Subjects: 18 community-dwelling elderly (83.2y, 63-95y) Playware Method: 9 training sessions with modular interactive tiles Training: 13 min. once per week. Total: 2h Context: Two elderly activity centers Tests: Pre- and posttest with Senior Fitness Test Performed by third party, blinded Test of functional abilities (mobility, agility, balancing, endurance, fitness): • 6-Minute Walking Test (6MWT) • Chair-Stand (CS) • 8-ft Timed Up and Go (TUG) • Tandem Line-Walk (LW) www.playware.dk Professor Henrik Hautop Lund hhl@playware.dtu.dk
