Abstract: Virtual and augmented reality sports training environments are disclosed. A user interacts with virtual players in a simulated environment of a virtual reality sporting event. In some embodiments, the user's actions and decisions are monitored by the simulated environment. The environment evaluates the user's performance, and provides performance feedback based on the user's decisions and timing. In one application, real life pitchers and their pitching data are tracked and replicated in a simulated pitching environment. A team of users may practice against a simulation of a pitcher they are about to compete against, swinging at pitches that they would see in a real game. Such environments may maximize effective practice time for users, and help develop better players with improved decision-making skills. Some embodiments include various pitch recognition training, which may be against replicated real-life pitchers.

Abstract: Certain embodiments employ an “out-of-band” mechanism to remove the physical controls for activating input peripherals from a portable device operating system and instead controlled by a separate peripheral control domain, isolated from the operating system domain by a machine virtualization/isolation technology. No additional hardware may be required. An adjunct I/O virtualization mechanism may also be included to abstract the guarded input peripheral interfaces, such that all attempts to turn them on from within the operating system are automatically redirected by the I/O virtualization mechanism to the peripheral control domain. The peripheral control domain may then conduct a policy-driven decision process to either allow, disallow, or request manual/explicit authorization of an access attempts. Physical access may be performed within the peripheral control domain.

Abstract: In certain embodiments, virtualization mechanisms used to defend against spying can also be used by attackers as a means to execute spying attacks more effectively. In certain embodiments, attack methods may use the virtualization mechanisms to surreptitiously activate input peripherals without the user's knowledge or authorization. In certain embodiments, a virtualized network interface may be employed in which all network traffic transiting a portable wireless system is routed through a remote control component within a peripheral control domain. The remote control component may be used by an attacker to communicate remotely with the portable device to send it peripheral activation commands. The remote control component can then activate peripherals via the peripheral access module without the user's or general-purpose operating system's knowledge or authorization. All other network traffic may be passed through as normal and expected to the general-purpose operating system.

Abstract: A method finds an error in a computer program. A plurality of execution breakpoints are set in the computer program. A portion of the execution of the computer program is simulated as recorded in the trace data in the reverse order until one a plurality of conditions is met, wherein one of the plurality of conditions is an attempt to execute a machine instruction associated with one of the plurality of execution breakpoints.

Abstract: A method and system debug a computer program by using trace data, which is a recording of the sequence of machine instructions executed by a program during a time period along with the addresses and values of memory locations accessed and modified by each machine instruction. After the time period, the method and system use the trace data to simulate the execution of the program during the time period under the control of a debugger. In addition, the method and system use the trace data to simulate the execution of the program during the time period backwards in time under the control of the debugger.

Further, at least a portion of the trace data is searched for the operating system instruction address. The execution time for an operating system instruction stored in the operating system instruction address is determined. The execution time is searched through in the database to find task related data. The task related data is displayed.
