Some people have difficulty controlling the touchscreen on an iPad or iPhone with their fingers, especially older people. The iPhone touch sensitive screen works on capacitance and it does not respond well to dry fingers.
Read on for some experiments I did and how to fix the problem!
Older people tend to have dryer fingers. Often they have to press the touchscreen on the iPhone very hard and I have met one or two people where their iPhone or iPad will not respond to their fingers at all. Thankfully there is a very simple solution. Simply Moisturise your hands with a water-based moisturiser! I find “MooGoo” to be particularly good.
Here are some tests that I did to show how effective this is.
I placed layers of tissue over my finger and tried to swipe my iPhone. (This is to simulate a layer of dead/dry skin).
With one piece of tissue over my finger, I could operate the iPhone perfectly.
Three layers and it started to be a little less responsive.
Five layers and the iPhone no longer worked at all, even if I pressed hard.
Here is a video of me trying to operate the iPhone with five layers of tissues on my finger. As you can see, the iPhone does not respond at all.
I put layers of tissue over my finger with a little bit of moisturiser in each layer. With moisturiser I could get up to 34 tissues and the phone is still working.
Here is a video of me operating the iPhone with 34 layers of tissues – you can see the screen swiping – the iPhone operates fine!
So, if you have an iPhone that sometimes seems a little unresponsive, I suggest using some moisturiser on your hands.
I also tested different moisturisers.
Using a zinc and castor oil style of moisturiser that is commonly used for eczema did not work at all.
But water based ‘MooGoo’ worked very well. The main ingredients are: “Aqua, Prunus Amygdalus Dulcis (Sweet Almond) Oil, Olea Europaea (Olive) Fruit Oil, Cetearyl Alcohol,Cocos Nucifera (Coconut) Oil, Squalene (Olive)”
