Abstract: A method for collecting feedback from at least one participant during a presentation and for providing the feedback to a first presenter includes, by a data processing unit connected to at least one participant device associated with the at least one participant, setting a time increment for collecting feedback from the at least one participant. At each time increment, feedback that is provided by the at least one participant via the at least one participant device is collected by the data processing unit. The feedback provided by the at least one participant is then associated with each time increment by the data processing unit. The data processing unit stores the feedback in a database connected to the data processing unit. The feedback is presented, via at least one presenter device associated with the presenter, to the first presenter.

Abstract: A recognition system is disclosed, including a representation of an object in terms of its constituent parts that is translationally invariant, and which provides scale invariant recognition. The system further provides effective recognition of patterns that are partially present in the input signal, or that are partially occluded, and also provides an effective representation for sequences within the input signal. The system utilizes dynamically determined, context based expectations, for identifying individual features/parts of an object to be recognized. The system is computationally efficient, and capable of highly parallel implementation, and further includes a mechanism for improving the preprocessing of individual sections of an input pattern, either by applying one or more preprocessors selected from a set of several preprocessors, or by changing the parameters within a single preprocessor.
