Abstract: Embodiments are disclosed herein that relate to aligning a near-eye display of a near-eye display device with an eye of a user. For example, one disclosed embodiment provides, on a near-eye display device, a method comprising receiving an image of an eye from a camera via a reverse display optical path, detecting a location of the eye in the image, and determining a relative position of the eye with regard to a target viewing position of the near-eye display. The method further comprises determining an adjustment to make to the near-eye display device to align the location of the eye with the target viewing position.

Abstract: A method of acquiring software profile information of a target software application includes receiving a programmed interrupt while executing an application in a computer system, servicing the interrupt such that call stack information is acquired and processing the call stack information to produce statistical information concerning function calls. The call stack information includes program counter and other information which is derived from the target application as well as operating system. Some or all of the call stack information may be recorded. The statistical information includes statistics concerning the number of samples wherein a series of functions calls are included in the call stack information and the number of samples wherein a set of function calls are at the top of the call stack information.

Abstract: A method of acquiring software profile information of a target software application includes Monitoring an application program for system calls, detecting a system call of interest to the user, acquiring stack information, and processing the call stack information to produce statistical information concerning function calls. The call stack information includes program counter and other information which is derived from the target application as well as operating system. The call stack information may be recorded. The statistical information includes statistics concerning the number of samples that any one function call is at a top of the call stack information, the number of samples that a series of functions calls are included in the call stack information, and the number of samples that a set of function calls are at the top of the call stack information.

Abstract: Filtering exceptions on a target computing device to selectively interrupt a host computing device based on rules. The rules represent user-defined scenarios, and each rule includes one or more criteria and a break decision. Upon detecting an exception on the target computing device, the target computing device evaluates the rules based on the criteria and information about the exception without notifying the host computing device. For example, a score is calculated for each rule, and the rule with the highest score is selected. The break decision associated with the selected rule is applied. For example, the break decision indicates that the exception is of interest and the host computing device should be notified, or that the exception does not match a scenario of interest and execution should continue without a break.
