3 Rome PIA in a nutshell

4 Rome PIA Personal IADL Assistant Aim: Providing video instructions on a tablet app to support the elderly (with/without dementia) in doing instrumental activities of daily living Easily recalling of the videos with the help of NFC (Near Field Communication) Tags Project duration: – In cooperation with UK, Norway, Spain PIA is an AAL JP project from Call 5

5 Rome Anna erzählt ihrer Familie, dass die Wärmepumpe kaputt ist. Es ist immer zu kalt Bei ihr zu Hause. PIA Netzwerk Tim uploads the video with the help of the PIA system. Anna can now watch it on her tablet. Tim also shares the video with other users on the PIA platform. PIA Portal Annas PIA Tablet 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. PIA Personal IADL Assistant

9 Rome Focus groups

10 Rome 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: 7 female, 8 male, average age older people: 15 female, 15 male; average age 73 Methodology PIA – Focus groups

11 Rome Results 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 PIA – Focus groups

12 Rome 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 PIA – Focus groups Results

13 Rome Problems foreseen People with severe dementia might not be able to use PIA Who provides videos? How can be ensured that videos are of good quality? How can technical barriers be overcome? How can tablets easily be charged? Need for training and standard processes Difficult to hear, understand and implement instructions simultaneously PIA – Focus groups Results

14 Rome Suggestions to make PIA more helpful Providing an overview (library) of available videos Changing screen colour according to topics Too many things on the screen, symbols should not be shown permanently Larger symbols Videos– simple language, familiar faces, not just showing hands, stoppable between each step, remote upload, searchable via voice control … PIA – Focus groups Results

15 Rome Suggestions to make PIA more helpful Search-/home-/emergency-button Easy to call technical support Recording features, reminders, shopping lists Adaptable to individual preferences, different kind of user manuals Connectable to TV Support usage of common apps PIA – Focus groups Results

16 Rome 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 PIA – Focus groups Results

17 Rome Prototype

18 Rome PIA - Prototype

19 Rome Usability tests

20 Rome Carried out in Germany, Norway and UK during January – February 2014 to analyze the usability of the first PIA - prototype identify problems and obstacles collect suggestions for improvement Participants were 6 formal/informal carer: 7 female, 8 male, average age 60 6 older people: 15 female, 15 male; average age 73 Methodology PIA – Usability tests

21 Rome 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 Procedure PIA – Usability tests

22 Rome 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 virtually impossible), 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 Results PIA – Usability tests

23 Rome 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 to identify) 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 Results PIA – Usability tests
