A device for detecting a wavefront that is defined by a plurality of contiguous light beams includes an array of lenslets for isolating the individual light beams and focusing each individual light beam to a focal point in an x-y plane. The device also has a plurality of clusters which are positioned in the x-y plane, and each cluster includes a plurality of pixels that are arranged in rows aligned in an x-direction, and columns aligned in a y-direction. Additionally, each pixel of a cluster includes both a first photocell for generating an x-signal and a second photocell for generating a y-signal, respectively, in response to an illumination of the pixel by a light beam. Further, the device includes circuitry for converting the x and y signals to digital signals and then using the digital signals to determine an x-y position for the focal point of the particular light beam that is incident on the cluster. A computer then compares the respective x-y positions of the various focal points to detect the wavefront. Depending on the particular application of the device, either photodiodes or phototransistors may be selected for use as the photocells in the pixels.

The method of claim 12 wherein the at least one event is scheduled such that data required to process the particular communication is provided to the agent substantially simultaneously with the communication. 15. The method of claim 11 wherein the precise time of future availability of the agent is used to determine a next opportunity for service (NOS) indicator for each of at least a subset of the skills supported by the agent. 16. The method of claim 15 wherein NOS indicators are generated for a plurality of agents associated with the call center. 17. The method of claim 16 wherein the NOS indicators for at least a subset of the plurality of agents associated with the call center are arranged in a visual display comprising a time line of NOS indicators for a given skill supported by the agents. 18. The method of claim 17 wherein the visual display comprises a plurality of NOS time lines each including NOS indicators for a particular skill supported by at least a subset of the agents. 19. An apparatus for processing communications in a call center, the call center providing for a given agent, in addition to scheduled breaks, variable rest periods for the given agent between servicing of communications by that agent, the apparatus comprising: a processor operative to determine a rest period for the given agent, based at least in part on one or more of (i) an agent occupancy level and (ii) which of a plurality of designated service states is associated with at least one of a particular skill and a particular type of communication supported by the agent, a set of rest periods being associated with each of the service states and including at least one specified rest period for each of a plurality of agent occupancy levels, a given one of the rest periods thereby being determinable based on agent occupancy level and service state, wherein the plurality of service states comprise at least first, second and third service states corresponding to a first service level, a second service level representative of an over-service condition relative to the first service level, and a third service level representative of an under-service condition relative to the first service level, respectively, such that communications are not handled by the given agent for at least a portion of the determined rest period; and a memory coupled to the processor and operative to store information regarding at least one of the agent occupancy level and the service states. 20. The apparatus of claim 19 wherein at least a subset of the service states are characterized at least in part by at least one of a waiting time measure, an average speed of answer measure, and a percent in service level. 21. The apparatus of claim 19 wherein the agent occupancy levels comprise one or more of a below target range level, a within range level, and an above target range level. 22. The apparatus of claim 19 wherein the plurality of designated service states comprises two or more of an over threshold state, a current jeopardy state, a future jeopardy state, a within-range state, an over served state, a queue empty state and an agents idle state, wherein the within range state is representative of the particular service level. 23. The apparatus of claim 19 wherein the rest period is determined for the given agent based on both the agent occupancy level and at least one of the service states for one or more skills supported by the agent. 24. The apparatus of claim 23 wherein the particular one of the service states corresponds to a worst-case one of the service states for a plurality of skills supported by the agent. 25. The apparatus of claim 19 wherein a different set of rest periods is associated with each of the service states for each of the plurality of agent occupancy levels, such that the rest period is determined for the given agent by determining
