Abstract:
This paper describes a hardware/software platform to acquire human body signals. In the field of physiological
computing it is desirable to have a system that allows the synchronized acquisition of signals coming from
different sources. Here is described how to unify the whole process of acquiring signals from both customized
hardware and low cost commercial devices such as Neurosky’s mindwave. A case study using this platform
is also shown: studying the feasibility of using sustained attention to access a computer. In order to do that
brain activity was measured using Neurosky’s mindwave. The participants in this study were asked to keep
their attention high/low for as long as possible during several trials. Experimentation was performed by 7
normally developed subjects and 3 people with cerebral palsy (CP). Our preliminary work shows that 60%
of participants might be potential users of this technology. Eventually, modulating the attention to access a
communication board ne
eds a scanning period greater than 5.76s.
