In the previous post I discussed how I got myself back in to Pac-man, and the little set of tactics I came up with that I thought made me good at it. Here I want to look at why I appear to be rubbish at Pac-man on iPad, or at least worse.

The iPad version of the game (well, iOS) introduces some new control options. Playing on the computer I simply use the arrow keys to move the little chap around, I'd even got as far as discovering that I could hold down an arrow key in advance of the turn I needed to make so he turned as soon as possible.

Moving to iPad gives some different options. There's a joystick control at the bottom of the screen, or I can take advantage of some of the other tablet input methods and control Pac-man by swiping the screen or tilting the entire device.

2006 saw the launch of the Wii, and with that came the popularity in far more physically involved methods of controlling games. As a culture we got pretty excited about this, suddenly computer games could be an activity as part of a healthy lifestyle. We even have a couple of Nintendo Wii's in our PE department now.

However, it's ruining my score.

It's about inefficiency. With my arrow keys underneath my finger tips, the time required from brain to Pac-man is significantly smaller than if I have to tilt an iPad a certain degree to make the same activity happen. It's also a far more practiced activity- my body is already set up well to make these subtle movements very quickly. This can't be said for swiping or tilting.

Obviously if I'd started playing the game using the other control methods it wouldn't have been a problem, I wouldn't have noticed. But it is interesting how the input method changes the nature of the challenge and the experience of the game as a whole.

Returning just briefly to the Wii again I want to pick up on a wider issue around this idea of inefficiency. After a fairly small amount of time playing Wii Tennis or similar you realise that you don't have to mimic the exact on court actions of Andy Murray to become a skilled player. Far more subtle motions with the controller will achieve the desired result. We refine our motions to speed up reaction time, maximum reward for minimum effort. There is some question as to whether this could be marked up as cheating- would using a more simple on/off type device connected to the Wii make me so much better at tennis that it's an unfair advantage? But that's a whole new post.
