Preach, my easily startled brother, preach. But yet your co-workers don't catch on that you jump-scare so easily?
We should make little signs or banners for people's desks. "Deeply Absorbed Programmer: Do Not Sneak Up On." Issue little handbooks on how to safely interrupt a programmer, as we do currently with sleepwalkers.
If I have to interrupt someone in an open-plan office and can't just message them to get their attention (seriously, what's wrong with just messaging people for non-urgent issues?), I am careful to approach them from the front or peripherally-viewable side and try visual cues first (hand-waving, etc.). I would NEVER use a physical alert method (touching them, knocking on their desk, dropping papers in on their keyboard, etc.). This is one of my several guarantees to the nation.
They do and they ask me "How can I come over without startling you" to which I reply "Message me on chat that you are coming over or get me a desk where I have my back to a wall".
I really dislike when someone walks over and stands behind me waiting for a good break point. While they may have good intentions I don't like being observed without my knowledge and it's probably just going to freak me out more when I "feel" your presence and turn around.
This! I am extremely jumpy and I hate being snuck up when I'm deep in thought/in the zone which I am as often as possible. If I notice you approaching me you can probably assume I am between tasks or took a break because when I am programming I have my music turned up and I can't hear people walking up and even my peripheral vision is limited in these situations. I can't tell you how many times someone has walked up next to me and I haven't noticed except for when I turn my head to see my laptop screen (where I keep all my chats) and catch them in the corner of my eye and almost fall out of my chair.
I try to not let this affect my level of focus because I really do think that's more important than a few scares a day but if I had my back to a wall then I wouldn't have to worry about it at all.
