I wrote once about vending machines, their current interfaces and their (futuristic) designs. The worst interface is the ones in which items are distinguished by a random code. Well, this one is even worse.
The vending machine had no slot to put money in or a pad to select an item. I was puzzled for a bit. I looked on the left and right side, but nothing there.
Then I looked at the separate vending machine on the right and although it's a coffee dedicated machine it had two pads: (1) the top one for the
machine on the left and (2) the bottom one for the machine on the right.
The money for both has to be inserted on the top pad. Weird and
A very interesting idea in the public bathroom to make the implementation simpler and save space.
I wrote about door design a few years ago and listed two similar examples:
Here's another nice design from an elementary school. I asked a child to open the door from both sides. Note the different handles and how a child (125 cm tall) interprets them. Note also the heigh at where they are positioned (chest height vs. over head height). However, while observing adults they often get confused with the pulling one (trying to push the handle at below the chest height).
A few years ago I wrote about Dyson Airblade and a similar product made by Veltia. These dryers blow out the jets or air streams and dry hands as quick as paper towels.
On the other hand the conventional heat and fan dryers are slow at doing their job (I almost always give up drying hands after half a minute). But they are small. While the Dyson Airblade (and all such dryers including the first one Mitsubishi Jet Towel) is big and bulky.
Airblade V on the other hand has a much smaller engine, looks similar to the conventional dryer and still blows out jets of air. It takes more time to dry hands as they need to be turned around. But still faster than conventional dryers. Although children can have some problems twisting their hands :).
I can't wait to try out their Airblade Tap.
Although I'm not particularly happy with having electricity in the tap (I know there are a lot of taps lightning the water based on its temperature). Even if all the safety precautions are in place I would not feel at ease.
This one is also from a friend visiting Mexico:
This tap is a personal favourite of mine!! It was in a restaurant in
Manzanillo and perhaps should have come with instructions!! There is a
small lever coming out of the tap (where the water comes out [aerator]) and to turn
the tap on you had to push this lever. You also had to keep it pushed to
keep the water flowing which meant you needed some pretty fancy finger
gymnastics to be able to wash your hands.
Well ... I have no comments :=). The designer of this tap mush have had imagination.
