Personalization - One squeezing channel is mapped to a pitch lookup table and the other controls the tempo. This allows for personlization of the SqueezeMan and for various experiments with different musical parameters. The infrared communication system also allows for influencing and manipulating other SqueezeMans, as long as they are in a line of sight from each other. One application allows for the players to hear each others' music through their personal headphones. This allows for the players to try and produce multiple voices interaction.
More complicated mappings allow for the players to change each others timbre and volume.
This enhances the musical collaboration with new possibilities for interdependent control. Gameability - The infrared interaction also allows for the development of musical games and challenges. In one application, the players try to control the tempo by matching the slowest tempo in the group. In other underdevelopment application the challenge is to repeat different musical lines in order to control the main melody.
