标题：Applications in cochlear implants and avionic: Examples of how neurometric measurements of the human perception could help the choice of appropriate human-machine interaction solutions beyond behavioral data
摘要：The availability of indexes linked to distinct mental functions suggests their use in theevaluation of the cerebral impact of human machine interface or devices by measuring theinduced cerebral activity. This approach could reveal additional information concerning theefficacy evaluation of the proposed device or interface, beyond the participants’ behavioraland verbal reports. The mental workload index (frontal EEG power spectra increase in thetheta band and simultaneous parietal EEG power spectra decrease in the alpha band) is anexample of these indexes and in this study it was employed to identify the most appropriatecochlear implant processor in one postlingually deaf 43 years old male unilateral CI user.Results were compared with those obtained in another study involving the selection of themost appropriate devices in a helicopter cockpit. Data showed a statistical significantdifference between sound processors (Freedom, CP810 and CP910) (F(2,180) = 3,046p=0.05. In addition, the trials in which the Noise filter reduction function was adoptedreported statistically significantly lower IWL values in comparison to the trials with No noisefilter reduction use (F(1,90) = 8,027 p = 0,006). The evidences support the capability ofidentifying the devices eliciting less workload level. Such devices would free up user’scognitive resources that will be available for other additional tasks.
