Hit It! is a game for the Android platform that is all about speed and quick fingers. You have to touch and move as fast as you can to see if you can beat all levels. The player’s task is to simply touch each appearing circle as fast as possible. The faster they are the more points they get. Players might improve their dexterity by trying to be the fastest guy in the high score.
This game is part of our research about the touch performance on mobile devices and also part of my work as a PhD student. While users play the game we measure where they hit the screen and how fast they are. By combining this information with the position and size of the circles we can estimate how easy each screen position is to touch. Based on this data we are hopefully able to predict user’s performance with different button sizes and positions. We plan to derive an according model and this model could possibly be used to improve the user interface of current smartphones.
We hope that we can collect data from thousands of players. That would enable us to derive information that is valid not only for a small number of people but for every user. We are, however, not interested in you contact list, browsing history, or phone number. Okay – if you are good looking I might be interested in your phone number but I don’t want to collect such data automatically ;). In general we don’t want or need data that enables identifying individuals. Thus, we do not collect those things or other personal information.
