GeZuMi can be seen as a Proof of Concept. The goal was to determine whether distances could be reliably calculated and then further processed with Bluetooth technologies. Overall, there are technical limitations to the Bluetooth concept and it is not perfect for determining real time locations.
To reliably work with the transmitted data, the filtering of the RSSI values would have to become more precise so that the unexpected spikes and drops of the values could be balanced out.
Ideally, with an improvement in distance and position calculation, more than three players should be able to join a game. The implementation of this feature would also include an improved generation of target shapes, to avoid having a random collection of edges and lines.
In the future, more gamification features will be included in the game. To incentivize more games, overall highscore lists are planned. This would allow players to compare their own group with the skills and speed of others and, hopefully, increase the team’s motivation.
Different types of levels or game modes are also in planning. One version would be to have a predefined game time, of 60 seconds for example, with the objective of matching as many target shapes as possible. Another alternative is the ‘blind mode’. In this game mode, only one player would see the target shape. They then need to quickly and clearly direct their teammates to their target positions.
