| Popis: | The P300-based Brain Computer Interfaces (BCIs) are widely used for communication purposes and proven to be fast and reliable. The present study aimed to identify the effects of a long term use of a P300-based spelling application for clinical healthy subjects under two display cases represented by a computer monitor and a head-mounted display (HMD). The typical 6 × 6 row-column spelling application was used by 7 participants under 12 recording sessions for both display methods. The results of the experiment showed that over time there is a statistical significant difference for the average accuracy rates for each display method. The average classification accuracies improved overall by a maximum of 21.43% for monitor display and 25.72% for HMD. However, the results of the experiment demonstrated that no statistical significant interaction existed between the two display methods. |
