AI summary

Methods and systems for applying biometric data to an interactive program executed by a portable device are provided. According to embodiments of the invention, raw bio-signal data is captured and filtered so as to determine the bio-signal of the user of the interactive program. The bio-signal is analyzed so as to determine biometrics of the user, which are applied as input to the interactive program. A setting or state of the interactive program is modified based on the biometrics. An updated state of the interactive program is rendered to the user, reflecting the modification of the setting or state of the interactive program.
