Method for dynamically adjusting an interactive application such as a videogame based on continuing assessments of user capability

A method of balancing a user's input to an interactive computer program with the program's output is obtained by continually measuring the difference between the user's input and the program's output and adjusting one or more parameters of the program's output so that the difference from the user's performance is progressively reduced. The adjustment may be obtained dynamically through negative feedback dampening of the measured difference (delta) between user input and program output, and/or by selection of predetermined apposite values for program output corresponding to the measurement of user input. The adjustment results in dynamic generation and/or selection of premodeled segments of interactive output in closer balance with user input. The adjustment method can be applied to video games, educational games, productivity programs, training programs, biofeedback programs, entertainment programs, and other interactive programs. In video games, the adjustment method results in balancing user performance with game difficulty for a more engaging game experience. It can also enable embedded advertising to be triggered when the user is in an optimum state of engagement. The adjustment method may be performed by projecting future trends of user performance, selecting predetermined or dynamically determined levels of value, modifying user control of input devices, or even modifying the program's challenges to user capability over time.

Authentication techniques in a monitoring system

An Electronic House Arrest Monitoring (EHAM) system of the present invention includes a transmitter attached to a monitored offender and a receiver positioned in the vicinity of the desired monitoring location. The transmitter and the receiver each have a pattern stored or generated therein for determining the interval of time between signal transmissions and receptions. The pattern is pseudo-random to offer improved protection against imposter transmitters, in other words the time intervals are selected to be unequal and randomly varying but the pattern is repeated or cycled to allow continuing signal transmission by the transmitter. The transmitter transmits signals at varying time intervals according to this pattern, and the receiver authenticates signals it receives as coming from the monitored transmitter based on the expected time intervals from the pattern. The pattern may include any number of time intervals and, in one embodiment, includes more than one subpattern to extend the length of the repeat cycle to increase the difficulty of defeating the monitoring system. As further protection against imposter devices, the receiver may verify the signals based on information unique to the transmitter included in each signal. The receiver may further use the received signals and unique time interval patterns to determine a number of operating states, including New Transmitter ID Received, Transmitter In Range and Locked to Transmitter, Transmitter In Range and Not Locked, Transmitter Out of Range, and Imposter Likely. The monitoring system may also include a remote host computer linked to the receiver or receivers to enable these operating states to be monitored remotely by enforcement personnel.
