This seems to be an real and important problem with capacitive touch screens. My elderly mother is often unable to make a touch register on recent Apple devices when a touch appears to have clearly happened and with reasonable force. She blames it on her fingers being "numb" but there genuinely seems to be a problem unrelated to her actions. (I've used the devices in question, and they appear to be fine. This is not…
What I found more surprising is that voice control isn't the solution, either. She is very reluctant to talk to Siri because it feels to her like there is an actual person there and she doesn't want to bother them. It would actually be better for her if you could choose a more robotic voice for Siri to make it seem more like a machine.
Not looking forward to getting older and having to interact with the brave new world that Big Tech will be bringing us. With some manufacturers you can't even drive a car without using a touchscreen -_-
