Arm-Swing Space: How Much Room Reaching Games Really Need
How much arm swing space do mixed reality games need? A 30-second reach test, plus tips for reaching, ducking and throwing safely in your room.
Floor space gets all the attention, but the thing that actually breaks lamps is arm-swing space. In a mixed reality game your arms go further than your feet, and you only find out the limit by hitting it. Here is how to measure and respect your reach, with Tank Avenger: Mixed Reality as the example.
Why reach matters in this game
Tank Avenger asks for more than steering. The product page describes catching a NUKE with your own hands and throwing it as far away as possible, cutting thin drone wires before they reach your tank, and leaning in while a helicopter hovers overhead. These are movements that cover far more space than the 2 × 2 metre floor area suggests.
The 30-second reach test
- Pick the exact spot where you will stand during play.
- Reach out to both sides, then straight ahead, then up as high as you can.
- Rotate slowly through a full circle with your arms out.
- Make a mental list of whatever your hands brush against: lamps, shelves, ceiling fans, door frames, framed pictures.
- Clear those objects away, or move to a better patch of floor.
Do it before you put the headset on, because afterwards you won't see the lamp coming.
Think in a bubble, not a square
The game's support page recommends about 2 × 2 metres of clear floor. Imagine a sphere around you, roughly an arm's length plus a safety margin in every direction. Your whole bubble needs to be clear, not just the floor under it. The sphere includes the space above your head.
Throwing is a special case
A throw takes a big arc, often with a follow-through. If you're asked to throw something far away, don't do it with a full overhand swing in a cramped room. A shorter, controlled motion still works in-game while keeping your hand out of the shelves. Practise the motion without the headset to find a safe version.
Common victims
- Ceiling fans and hanging lights.
- Wall art and mirrors.
- TVs and screens.
- Lamps on side tables.
- Doors and door frames.
- Other people walking in.
Reduce the risk further
- Face open space. Turn so your throwing direction faces the clearest side of the room.
- Keep controllers strapped on. Use the wrist straps your controllers come with.
- Keep the boundary on. The terms ask you to keep boundary features enabled.
- Use the table. A table arena reduces how much you need to move.
- Take breaks when you're tired; sloppy movements come with fatigue.
After a near miss
If you nearly hit something, stop, move it and carry on. Virtual objects don't protect you from real ones, as the terms put it.
Make it routine
Add the reach test to your pre-play checklist alongside clearing the floor and scanning the room. For what the game involves, see the Tank Avenger page.
Footwear and floors
Reach isn't only about arms. Slippery socks on a hard floor turn a sudden lunge into a fall. Play in grippy shoes or bare feet on a dry surface, and avoid loose rugs that can slide. If you do use a rug, make sure it's flat and fixed.
Good footing lets you move your arms confidently without worrying about balance, and it keeps the whole play bubble safer.
Practise the motions without the headset
Before you rely on a big motion in the game, rehearse it in the real room with nothing on your face. Mime the catch, mime the throw, mime ducking. You will discover where your elbow meets the shelf, and you can change your stance or your spot. Ten seconds of miming in daylight is far cheaper than a broken lamp. Do it again if you move your furniture.
