The article talks about something I'm curious about: which hand you hold your phone with and which hand you tap with. I'm more or less right-handed - fairly ambidextrous for many things - but I write with my right hand. I always hold a phone or similar device with my left hand and tap on it with my right hand, like the middle example in the three illustrations on the blue background midway through the article (the one that it says 36% of users do it this way). It never once occurred to me to hold a phone with my right hand and tap on it with my right thumb, like the leftmost illustration in that image (49% of users). If I do tap with my thumb, I still have the phone in my left hand and use my left thumb. I think this comes from my earlier days with pads of paper and a pen or pencil. I wanted to write with my right hand, so naturally I held the pad in my left hand and the pen in my right hand. Of course I've always assumed everyone does it this way: hold the device in your non-dominant hand and tap on it (or write/draw on it with a stylus) with the dominant hand. It's a total surprise to me that people would actually hold a phone or device with their dominant hand. I guess it makes sense if you're always using it in a one-handed manner, but for me it is just something that never even came to mind as something to try. Since I'm holding it in my left hand anyway, if I do use a thumb it will be my left thumb. Not saying one way or the other is right or wrong, of course. I wonder if this is one of those things where people fall into one of two (or more) groups, and don't even know the other groups exist?
