ABSTRACT
For a long time, literature has identified some psychophysiological measures that proved reliable to assess cognitive states in controlled conditions. Smaller, more reliable and more affordable sensors made the industrial community dream to design systems that would adapt themselves to the ability of their users to operate them. Thus an important human factors question must be asked: what is the impact of such a feedback on users' performance and cognitive workload? We designed a protocol to compare the influence of a cognitive load feedback in a Multiple Object Tracking task. Reliability of this feedback was also evaluated. Performance in a dual task paradigm, pupil dilation and the Overall Workload Scale were used to assess cognitive load.

Spectrum monitoring in heterogeneous cognitive radio network: How to cooperate?
The spectrum‐monitoring is a prominent technique to detect the reappearance of the primary user (PU) during the cognitive users’ (CUs) data transmission. However, the imperfect spectrum monitoring (SM) causes a delay in the identification of PU that ...
Real-time spectrum occupancy monitoring using a probabilistic model
The scarcity of the radio spectrum has motivated a search for more optimal and efficient spectrum management methods. One of these methods is spectrum sharing, which multiplies the number of devices that can use this resource without causing harmful ...
