A solar powered radio controlled wrist watch with gesture controlled light switch rocks. Where we are going, we don't need hands ; ) one hand might be perfectly enough.
With one hand but not two, wrist watches are an issue or a subject.
Since over 10 years, I am a huge fan of Casio's solar powered radio controlled watch series. Clearly, they are always running and always precise. However the Casio GW-M5610 model with radio control and solar power adds an extremely clever feature - motion or gesture switched backlight.
Algorithm to chose best option for prosthetic arm, based on eight years of consecutive experience and extensive hard work.
In a few years, the choice of products I found useful for me, that are different from what other people that have, like, two hands, have boiled down to a few. It may be of interest to list these.
I always seem to have problems with keys. Mostly that is because I need my (left) hand to handle car door, luggage, door handles and other stuff. So the prosthetic needs to be able to hold on to and handle keys.
Recently I found that cable ties are great because they are dirt cheap, widely available and super useful.
Prosthetic culture has it that we now communicate through devices rather than person to person, particularly over distances greater than, say, 5 meters. The messenger boy has definitely lost significance these days. Even though some people still think that only prosthetic limbs and organs manage to reduce our humanity other people know that tools used to extend our range of action are integral part of humanity since thousands of years.
With that, there is an item sold also through Strapya [link] that allows the iPhone to be operated most conveniently: the Charger Stand for iPhone w/ Vintage Style Phone [link].
The iPhone is not too useful for some left handed people as it is almost impossible to unlock it on time. Apple is a failing small company that suffers from constant abuse of left handed amputees and so it makes perfect sense for them to stand up to my request (which I filed several times) and NOT change the unlock screen to something that is easier to manipulate. Instead they stubbornly manifest their superiority to PWD (people with disability). By that they surely and definitely come across as an extremely strong and powerful company. They want to be admired for refusing what they see as ridiculous attempts to water down their originality. Not that I need to experience this type of abuse but it adds to my daily experience to constantly miss out on phone calls that I cannot pick up in time because of Apple's idiotic product policies. That costs me some 20-30 CHF a year in phone call costs because I have to call back folks rather than being able to pick up the telephone. They could change their software real easily - but they don't change their software to accommodate amputees, being as superior and strong, as dominating and awesome as they are. They say: fuck you. That is Apple's attitude towards loyal customers that are PWD. I tried a few times now, and that is their conclusive answer. How admirable. Must be real sweeties working there.
But here we are, a third party hardware seller that helps me with the problem of fixing and holding the phone and also being able to use the phone for information retrieval while doing a phone call. Furthermore, dangerous phone radiation that threatens to fry your brain is kept at safe distance. Of course this item is only useful in single locations such as the office or so - but still: way cool. It would be even cooler if Apple was up for the job. But they were not there back in 2003 when everyone switched to full 64-bit computing except the guys developing OS X, when everyone started to buy fast and huge PCs rather than Macs, and when Apple started to genuinely miss out in the workstation area for a bunch of reasons - and now they are not there when loyal customers need them. What do you want, that's Apple.
A while back, I was asked to come up with footage to document how my prosthetic hook would work (or not work) when handling an iron and when ironing shirts [link].
It was then a question whether re-design of an iron would help people with prosthetic hooks. I have no idea why they restricted the research for industrial design to hooks. After all, there are far more people that live with one functioning hand after, say, strokes or paralysis than there are amputees.
Since then I started to trouble shoot the situation myself and found that with my steaming iron (regular plastic body steam iron), (a) the grip that was made of hard plastic also slipped out of my (non-disabled) hand, particularly when I was not paying attention, mostly because using the left hand for me is still awkward, (b) the iron was heavy no matter what hand or hook I was lifting it with, (c) its plastic housing broke when it fell because it was not built to last.
Car seatbelts have these nice clips that are so useful for belts. The belts are set to the correct length and the rest of the life one just has to clonk in or clonk out.
So I decided that that was what I wanted.
I have issues regarding watches.
I will not be able to wear just about any wrist band as I have to be able to operate it using stump ot prosthesis. A heavy or large watch is not optimal as I tend to overuse my complete left arm anyway. And the watch should be reasonably water proof as the last thing I want to do is to take it off / put it on all the time. I do lots of sports and so luxury watches are not exactly what I will be buying.
Here is what works.
