Further Study - Discussion and Conclusions

6. Discussion and Conclusions

6.4. Further Study

Further study in the area could include testing with the participants’ own phones. In that way they would already be familiar with the interface elements. Participants’ comments support this. One participant mentioned that the games were too short. She was not sure whether she was able to get to know the user interface elements well enough. A few participants pointed out that some elements behaved in an unusual way, but maybe they would get used to them after a longer period of use. There were many comments by the participants on the fact that performance was better towards the end of the test when they got more practice and learned to play the games. The effects of practice can be seen in the logs. The learning effect cannot be completely avoided and it could be argued that it should not be. In order to get more reliable results, the users should get to play more.

To take the learning effect into consideration, the test design might include longer games, playing more sessions or testing on multiple occasions with the present game set. The practice games could be then discarded from the data. The test games should concentrate on using one interaction at a time, so the participants would be able to observe easily the functionality of an interface element. It may be worthwhile to

consider making the games also more straightforward, because some participants commented they did not understand how a game was supposed to be played, which affected the log results. If the games are played in a session consisting of a number of games, like in this study, the games should be kept relatively short. That way the participants will remember what happened in the first game.

Further study in the area with a larger number of participants is required to acquire statistically valid results. In further research it is important to choose the test phones carefully. They could include a model with a lower resolution camera. All phones should have the same display resolution if the games are designed for a certain size of the display and are not scalable. It is also important to get log data on all games and make sure the data is usable.

In the future game studies could involve testing an actual photo game, where the photos are used for some purpose in a game. It would also further clarify whether the quality of the pictures is significant for the players.

The selecting or designing games for the tests should focus on the enjoyment of the players. There were some comments about the fun factor of the tested games. Take a Photo confused some participants, because they did not understand the meaning of the game. It was also rated the most boring game, since it did not have a good game idea.

The Sheep Game was voted the most enjoyable and fun game. It had a nice idea and it offered a challenge. Participants also liked Curling and Number Game for the same reasons. Some of test participants commented on the post-game questionnaire that Take a Photo was a boring game, because of its device dependency. The player could not influence the results, because the fastest device won.

It is possible to design games for mobile phones. Designers should consider the special characteristics of the mobile phone and its technology and use them to their advantage. There are many examples of fun and popular mobile games that are developed specifically the device in mind. For instance, MUPE MiniGames are short, which is ideal for games that are meant to be played while waiting. Also, the means of interaction are very simple. They deal with latency by loading the needed data in between active game sequences. Minigames are multiplayer games, which suits the mobile phone’s connected nature well. In addition, they include typing games and camera games. Both of these gaming methods are very well suited to the mobile phone.

Camera games have a huge potential, since the number of camera phones is continuously increasing. Camera games are suited to all phones in that they use simple interaction methods that are not dependent on the design of the user interface elements.

However, if competing on the speed of taking photos, the phone with the fastest software and hardware wins. Camera games are also very well suited to casual gamers, since they do not require previous experience in gaming.
