I'm starting to find that HUDs in games clutter the screen and take away from being fully immersed in the game. I like games that force you to pay attention to what's going on in the game and not numbers/markers on the edges of the display. What are some of your favorite games to play with no HUD? Here are a few of mine:
Astroneer - this game has tool tips on screen but that's about it. There isn't even an inventory, all objects are interactive and you can physically place them on your backpack.
Battlefield 1 - super gritty and immersive, but playing without a HUD really puts you at a disadvantage online.
Red Dead Redemption 2 - I liked that you could hide the HUD, but the mini-map was a tap on the d-pad away if you get lost. It was a super immersive experience!
Grand Theft Auto 5 - maybe not designed to be played without the HUD, once you get used to the layout of the city this becomes a lot easier, and you focus more on landmarks to navigate and again this really increased immersion. Sometimes finding things in missions wasn't obvious and required consulting the map but otherwise this was enjoyable.
I completely understand how overcluttered and distracting some HUDs can become. I have found however that fully HUDless experiences tend to be more of a novelty than an increase in immersion.
If I’m playing a shooter and don’t have information on, say how many magazines I have, I find that more distracting than immersive. In real life I could quickly pat my vest to know. A HUD can be a replacement for information that seems intuitive to have because in a real situation we’d have kinesthetic feedback.
Basic information like health while injured is simply too useful. Realistically my health isn’t defined by a single variable bar nor is it restored instantly from a grievous wound by a using a syringe, so I find that seeing the bar is useful for succeeding in the game even if it is equally as unrealistic.
Something like the iHUD mod for modern Fallout games is my ideal HUD. It is modular and I can define what information I see, what information I don’t, and for how long the information I do get stays on the screen. Health can be set to only show at certain thresholds, the compass directions or map markers can be disabled unless I ask to see them briefly. Other elements similarly made optional.
I’ve played fully HUDless in both Metro games and in modded STALKER games, and each time I do I find myself going back to having at least a minimal informative HUD.
I don’t hate HUDs and I think most people who try HUDless don’t actually hate them either. What is hated are obnoxious tool tips, flashy HUD animations, and floating intrusive quest markers. If UX designers do their jobs right, people don’t know they did anything at all.
I think you hit the nail on the head, give me what I need to know when I need it, and make it more environmental when possible. Halo for example had the assault rifle show the ammo count on the gun itself and other games have as well, there are countless other ways to give information organically to the player.
There are diegetic elements like that, but also how the non-diegetic HUD delivers information.
When is it giving information? Is it giving me information I don’t actually need at the moment. For example a first person game that always has a compass or minimap. Maybe I want those sometimes, but do I want them always?
What are the visuals of the HUD like? Are they easy to read? Are they distracting? HUDs that have stretched and difficult at a glance fonts are a bad idea to me. Simple fonts that can be read against a variety of background colors are seemingly underdesigned to many UX designers, but it’s all I want sometimes.
Do HUDs have needlessly animated elements? Sometimes just putting a plain and simple number or bar on a screen is enough, but many games add so many artistic flourishes that it gets in the way of the game visuals.
HALO CE had its shield bar with the little health dots underneath. Technically diegetic, but obviously a gameplay element. It wasn’t distracting, it was clean and easy to read, it gave information that was constantly relevant.
I much prefer a compass to a mini-map, for me the mini-map is the worst offender in terms of pulling my attention constantly into one corner of the screen. Halo's motion sensor was good in that sense too, I'd check it but not constantly.
