this, an analysis of the user record must be performed, in order to obtain objective
measures. Besides the objective measures, it is also important to collect subjective
measures of the user satisfaction. A survey over the users view on the system could
contain questions such as: Use satisfaction; Use difficulty; Utility; Learning facility; Error
recovery facility; …
Classroom deployment feedback
After each of the sessions, the lecturer will provide its subjective impression on the
adequacy of those technologies to the particular lesson type. It will be recorded though a
questionnaire comprising items identifying time and difficulty needed to prepare the
session, comfort during the lecture, … In addition, the same lesson, using classical
procedures, will be imparted to a control group, and objective measures as time necessary
to finish the lesson will be also derived. Several different lecturers will use the described
deployment for a same lesson, and their distinct opinions and performance measures
analysed.
The students will also provide their subjective impression on the adequacy of those
technologies to the particular lesson type using an adequate survey. Regarding efficiency
of the technologies, an objective exercise to assess the students learning performance will
be performed at the end of each of the sessions.
Conclusions
This work in progress is yet at its initial stages, so there are no clear conclusions yet on the
applicability of this system. The following key aspects need to be addressed in the next
steps of the research:
• Define domains of application related objects and manipulations.
• Link the described basic gestures and actions with manipulations of objects in a
more formal way, by means of a simple and natural gesture based language, which
should be similar across domains.
• Implementing a prototype system, using ad-hoc software for control of virtual
objects.
• Define lesson contents, and prepare initial support material for it.
• Record lesson and obtain feedback data
• Analyse feedback and tune the system
In this research we will be investigating the limitations of our deployment. It is clear a
lecturing system only based on this case of interaction would be difficult to operate, and
surely a multimodal control method must be deployed, including additionally electronic
inking procedures in chalkboard on in touch based interfaces, voice recognition and
control procedures, or others.
