I've played a lot of games in my time. So when I first saw augmented reality my brain started to wrap itself around how it could be used in a gaming context. Having never worked with any sort of pose estimation techniques before, I decided to (perhaps foolishly) embark on turning my masters project in to a simple augmented reality board-game. One of my inspirations for this project came from the (back then) contemporary Playstation 3 title, Eye of Judgement. Despite it's modest 330,000 unit sales, it was still one of the first commercial games to heavily integrate augmented reality, as a type of game mechanic.
Augmented reality can help properly mesh video and board games. It enables us to retain the hidden information - something one player should know, but another should not - which is crucial when several people play together. Additionally, the computer can handle tedious tasks that the players would prefer to avoid, like tedious math or convoluted rules. The cherry on top is the fact that the computer can also manage non-player elements in a much more interesting manner. For example, the computer could control an additional Ai player for the other players to play against.
