Berlin Brain-Computer Interface-The HCI communication channel for discovery

摘要: The investigation of innovative Human-Computer Interfaces (HCI) provides a challenge for future interaction research and development. Brain-Computer (BCIs) exploit the ability human communication control bypassing classical neuromuscular channels. In general, BCIs offer possibility people with severe disorders, such as amyotrophic lateral sclerosis (ALS) or complete paralysis all extremities due to high spinal cord injury. Beyond medical applications, BCI conjunction exciting multimedia e.g., dexterity discovery, could define new level possibilities also healthy customers decoding information directly from user's brain, reflected in EEG signals which are recorded non-invasively scalp. This contribution introduces Berlin Interface (BBCI) presents set-ups where user is provided intuitive strategies plausible interactive bio-feedback applications. Yet at its beginning, BBCI thus adds dimension HCI by offering an additional independent channel based on brain activity only. Successful experiments already yielded inspiring proofs-of-concept. A diversity application models, say computer games, their specific now open aiming further speed up adaptation increase learning success transfer bit rates. complex distributed software system that can be run several communicating computers responsible (i) signal acquisition, (ii) data processing (iii) feedback application. Developing system, special attention must paid design serves unit. should provide about her/his way intuitively intelligible. Exciting discovery applications qualify perfectly this role. However, most these incorporate developed especially haptic devices, joystick, keyboard mouse. Therefore, novel purpose allow animated objects do not frustrate case misclassification decoded signal. able decode different types activity, sensory perception motor intentions imaginations, movement preparations, levels stress, workload task-related idling. All diverse incorporated scenario. Modern development technologies researchers know-how corresponding strategies.
