  3. PIA in a nutshell

  4. PIA Personal IADLAssistant • Aim: Providing videoinstructions on a tabletapptosupporttheelderly (with/withoutdementia) in doing instrumental activitiesofdailyliving • EasilyrecallingofthevideoswiththehelpofNFC (Near Field Communication) Tags • Project duration: 01.03.2013 – 28.02.2015 • In cooperationwithUK, Norway, Spain • PIA is an AAL JP project from Call 5

Anna tells her family that her heat pump is broken. It’s always cold at home. The family has heard this before. The heat pump works very well. They decide to record an video and to use the PIA platform. Tim, Anna’s son, records a video with the help of his smartphone. He explains the usage of the heatpump. He buys sensors and attaches them to the heat pump. Tim uploads the video with the help of the PIA system. Anna can now watch it on her tablet.

  9. Focus groups

  10. Methodology PIA – Focus groups • Carried out in Germany, Norway and UK during January – February 2014 to • ascertain people’s views on mock-ups of the PIA system and its planned functionality, • check out current design assumptions and • obtain further information about potential users. • Participants were • 15 professional carer: 7female, 8male, average age 60 • 30 older people: 15 female, 15 male; average age 73

  11. Results PIA – Focus groups • General impressions • Most like the idea of PIA, understand the overall aim • Potential users: singles, widowed people, people who struggle with common manuals … • Useful for all areas around the home, things never done before/not used very often … • PIA as a good alternative to common manuals, as cognitive encouragement, chance to increase independence • PIA might increase stimulation, health, fitness, coping strategies

  12. PIA – Focus groups Results • Technology • Screen – good quality of pictures (UK, DE), simple/boring (NO Car), enlarged font size (NO OP), most preferred screen size: 10″ • Audio – sound needs to be (a lot) louder • Tags – simple enough (OP), not easy to remember where and what for (Car) • Number of tablets – one tablet is enough • Battery - reminder if battery is running low

  13. PIA – Focus groups Results • Problems foreseen • People withseveredementiamight not beabletouse PIA • Who providesvideos? • Howcanbeensuredthatvideosareofgoodquality? • Howcantechnicalbarriersbeovercome? • Howcantabletseasilybecharged? • Need fortrainingandstandardprocesses • Difficulttohear, understandandimplementinstructionssimultaneously

  14. PIA – Focus groups Results • Suggestions to make PIA more helpful • Providing an overview (library) ofavailablevideos • Changingscreencolouraccordingtotopics • Toomanythings on thescreen, symbolsshould not beshownpermanently • Larger symbols • Videos– simple language, familiar faces, not just showing hands, stoppable between each step, remote upload, searchable via voice control …

  15. PIA – Focus groups Results • Suggestions to make PIA more helpful • Search-/home-/emergency-button • Easy tocalltechnicalsupport • Recording features, reminders, shoppinglists • Adaptableto individual preferences, different kindofusermanuals • Connectable to TV • Support usage of common apps

  16. PIA – Focus groups Results • Market • Future usage: quite mixed, some would use/buy PIA, others not • Price: opinions vary highly, depend on • what needs to be bought (tablet or app), • which services are included (updates, access to all videos …) and • whether person already owns a tablet or not

  19. Usability tests

  20. Methodology PIA – Usability tests • Carried out in Germany, Norway and UK during January – February 2014 to • analyzetheusabilityofthefirst PIA - prototype • identifyproblemsandobstacles • collect suggestions for improvement • Participants were • 6 formal/informal carer: 7female, 8male, average age 60 • 6 older people: 15 female, 15 male; average age 73

  21. Procedure PIA – Usability tests • Questionnaires: demographic data, affinity for technology • Tasks • Carer: recording video instructions (making tee, setting an alarm), link them to tags • End user: execute the recorded tasks • System usability scale • Interviews

  22. PIA – Usability tests Results • App is considered a useful tool, this is especially true of the carers, a period of adjustment or training is needed for the end users to use the system effectively. • Difficulties – End user • manipulating the controls on the pad to reverse or pause the video (these are small and if the end users doesn’t have the dexterity needed virtuallyimpossible), • issues around scanning the tags • variations in the ability of the end users to see and hear the videos, for some the volume was not adequately for others this was not a problem • problems in listening, watching and executing the tasks simultaneously

  23. PIA – Usability tests Results • App is considered a useful tool, this is especially true of the carers, a period of adjustment or training is needed for the end users to use the system effectively. • Difficulties – Carer • some forgot to start the recording (touching the red button) • saving the video instead of deleting it (symbols are too small, not easy toidentify) • forgot to open “link tag” before holding tag against tablet • difficulties in choosing the right video before holding tag against tablet • finding sensor at the back of the tablet
