Either way, a fun idea!

Your idea sounds great - can you give me a suggestion (e.g. a M-C/Mouser/Digikey part#)?

Here is an example of someone building a touch midi controller [0] with nothing more than a custom PCB and some resistors or a touch input device with varied inputs like sliders and buttons [1].
but seriously, this is a neat idea. and kudos to OP for building a full prototype -- this is the level of geekery I show up for.
I remember the days of T9 on the old Nokia phones. I was so good that I didn't have to look down at the screen.
My favorites were fixed in my phone. I knew how many down clicks on the button would land on the right friend/family member. I could literally send messages from my pocket.
And yes, I admit -- I did engage in texting while driving. And this is the part where I justify it -- "but I had eyes on the road the whole time!"
Oh! and there was old skits on late nite where people woudl compete with the old morse code guys.
To be clear - I am not sending myself long emails! I am sending one or two words, like "TEMP PROB" or "MULCH" to jog my memory in the morning. And for that, it has worked flawlessly.
Also, from the guidelines: "Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something."
