....been commonly used ever since Bolt s early Put that there [4] Both decision and feature level require natural multimodal data, e.g. for utilizing statistical techniques. This controversy leads to a chicken and egg problem. One of the solutions is to use Wizard of Oz style of experiments [23]. Where, the role of a hypothetical multimodal computer is played by a human behind the scene . However, this method does not guarantee a timely and accurate system response which is desirable for eliciting adequate user interaction. Therefore, in the next subsection we present a gesture speech ....

....using speech and direct manipulation. In our laboratory, we are building NEIMO, a multi wizard generic WOz platform that automatically digitizes and records behavioral data ranging from low level physical actions to high level commands performed by a subject using a multimodal user interface [SC93] Analysis from experimental methods are performed on real data, not on approximated values. This benefit is counterbalanced by the volume of behavioral data and the difficulty of identifying the appropriate parameters for the experiment. We believe that a WOz computer platform which ....

Observations are currently performed within usability laboratories. These laboratories are well equipped with analog recording which requires time consuming analysis. The aim of NEIMO is ....

....platform that would make possible the observation and analysis of multimodal interaction. With recent advances in interactive media, multi modal user interfaces are becoming popular. So, we have adapted the WOz technique for the experimental evaluation of modalities for human computer interaction [Salber 93] 2.2 The NEIMO Testbed 3 NEIMO (New Evaluation of Interfaces using the Wizard of Oz technique) is a generic and extensible multimodal WOz platform. It is designed and developped for evaluating communication modalities in human computer interactions. The goal of the NEIMO project is to ....
