I agree with all the other posts, this could be useful for those in the early stages of Dementia, however as the disease progresses the ability to remember to do just simple tasks can be challenging.
Some of the comments brought back memories of what my dad used to do. He was one for unplugging everything at night, but then forgetting to plug them back in and blaming 'visitors' in the night for breaking things.
We also bought him a Dementia clock. In the early stages of Dementia, he thought it was wonderful, however he still insisted on unplugging it every night and then not plugging it back in. It took about 5 months, lots of stickers, tape etc to get him to leave it plugged in, but I think then it was more that he had forgotten about it and over a few more months he stopped taking notice or believing it.
Dad got a bad cold and rather than drive 20 minutes back to his house just to give him some tablets before he went to bed. I tried calling him on the telephone to tell him to take them (My simple version of a medicine reminder). I had left them on a side table next to the phone, with water. Could I get him to understand, nope! I had to drive there and discovered the tablets and water had been cleared away (probably as soon as I'd left that afternoon) and they were found hidden under the sink in the kitchen.
We also had a care call system installed with door sensors to try to stop him from going out at night. This just became an annoyance for him and a disembodied voice talking to him when he opened the doors started to really upset him and stress him out. It lasted 3 weeks before he ripped it out. He thought strangers were constantly in his house.
As someone else mentioned most gadgets these days require a broadband connection, this was also something dad wouldn't accept in his house, something else plugged in! We tried hiding it upstairs under a small chest of drawers, but he discovered it and unplugged it and hid it somewhere else, we didn't find it for months. So we had to give up with that.
Our reliance on technology really worries me, more and more things require it. We have to remember pin codes, passwords etc and are told to change them often and not write them down. But what happens when we do get older and our memories worsen with age or we start with Dementia? I think I am of an age where I am very comfortable with technology, I spend most of the day on a computer, a tablet or a phone. I use a smart TV, have an Alexa, satnav in car etc and I do most things on-line. But things change so quickly these days and it's so easy to get left behind and even though I know what I am doing now, the question is will I still be able to cope with it as I get older? Will I still be able to adapt and understand it? Also, will this younger generation who are growing up surrounded by technology and everyday simplified tasks, be able to cope when they age and their memory declines and they can't deal with change anymore? No matter how many technological devices are introduced into our daily living, will we still remember as we age, to press that button to access something, talk to the room to turn on the lights, the tv etc, or fill the kettle with water before we tell it to switch itself on?
My dad was about 76/77 when we started noticing signs of Dementia. However he managed well still living at home for another 5 years, doing the mundane, routine tasks, washing, shaving, brushing his teeth, housework etc, food shopping, heating things in a microwave or on a hob, driving, going the bank and signing his name for money. However, I have to admit he was a technophobe and hadn't really embraced any technology so it was almost guaranteed we would have had a problem with trying to introduce anything new.
What I'm trying to say is that being able to do simple everyday routines manually are the things that enabled my dad to survive as long as he did with still living at home, his deep set memories of routine still worked. However, my question is what happens as technological advancements start to replace many simple tasks and we adapt our routines to this technology, are we taking the simplicity out of them and no longer establishing those deep routed routines because things are constantly changing and upgrading? Yes we think saying out loud 'Alexa, turn the light on' is simple but we have to rely on our memory to ask that question, rather than see a lamp, go to it and switch it on. What do we do if there is no switch anymore, do we sit in the dark?
I'm sorry I know your trying to help but sometimes turning to technology to solve a problem or help, is not always the answer. Having visits or calls from an actual person, being able to hold onto something physical like a photo and being told or helped to do something can never be replaced in my opinion.
