A method to authenticate a server to a client is provided, including in-band and out-of-band techniques. At least a first shared secret identifies a server path, including a plurality of pre-defined locations on a frame of reference (e.g. a grid). An authentication session is initiated upon receiving a client identifier at the server-side resources. A current session instance of the grid is presented to the client, populated with characters. The process includes sharing between the client and the server a challenge identifying a random subset of the plurality of predefined locations in the server path, and a response including characters that match the characters in the locations on the server path identified by the challenge. As a result, client is capable of verifying that the server has access to the first shared secret. Then a protocol is executed to authenticate the client to the server.

The invention allows the interpolation factor, a critical parameter in sample rate conversion systems, to be computed in a real-time system where there is a complex relationship between a DSP clock and the data clocks. Typically, two or three of the clocks in such a system will have simple relationships (such as CLOCK1=2*CLOCK2). This relationship leads to degenerate cases where, in fact, there are only one or two clocks to consider rather than three. Furthermore, the invention allows for input data rates that are higher than the DSP clock rate. The invention also provides for an arbitrary time delay to be applied to the output signal.

In a multi-carrier transmission scheme (frequency domain multiplexed—FDM), a single high rate data stream is split into multiple lower rate data streams each transmitted over a different carrier (e.g., a tone or bin). The data rate possible from a multiple-carrier transmission scheme is theoretically equivalent to the data rate possible from a single-carrier (including baseband) scheme with the same composite bandwidth. The scheme allows for a communications system that can selectively send each data signal (e.g., audio data, video data, raw data, etc.) partitioned out into full and half duplex sections (e.g., tones). The scheme can have a reduced complexity and cost and use less bandwidth. This is done by being able to selectively split a data signal into both full and half duplex tones.

In the preferred embodiment of the invention, tracking points on the input device which is in the form of a planar “T”-shape wand with a cross piece and a camera allow computer users to input natural swinging movements into a virtual environment for gaming or other three-dimensional applications.
