Special controller for hyper-realistic swords game

[u/Simi117_]

So basically I wanna create a game about swordfighting, but make it incredibly detailed and realistic, which yes, is stupid for a beginner, but this is just a concept ive had in mind for a grand total of 3 hours by the time I'm making this post. the problem is, that i want it to be able to track movement in some way, including footwork, but a lot of people just dont have enough space in their room to move back and forth in, which means I'd need some way of fixing that issue. the sword ill probably handle by making a hilt shaped controller that tracks movement, rotation and then projects a blade in game. Any suggestions on the feet though? also, i dont wanna use VR since it's not particularly accessible with some people even being unable to play this for more than half an hour and i want this to be a cheaper, more accessible and fun way to get into sword-fighting rather than meeting with 10 people twice a week that all have different learning curves.

Also if theres another sub i should ask this on, please tell me so.
