RealTime Biosignal Workstation
RealTime was a sophisticated biosignal acquisition, real-time analysis and feedback system. It was qualified for various clinical routine and research applications, such as:
- Clinical EEG and EKG
- Psychophysiological experiments
The biosignals were amplified and sampled by a 16-channel Biosignal Acquisition System, an analog/digital biosignal measurement unit, acquiring EEG, DC-EEG, EKG, EMG, EOG, respiration, temperature and GSR signals. It features true 16-bit resolution and a frequency response from DC to 4 kHz (20 kHz for single channel). The samples were fed to a NeXT computer utilizing the DSP port or an Intel 486 computer running NeXTStep with an add-on DSP card. Video images could be processed by the NeXTdlmension.
The RealTime software consisted of an extensive set of modules for preprocessing, analysis, display, and sound, which could be arbitrarily connected and assigned to biosignal channels. Such a network and its associated parameters could be modified even during a recording session. High-quality acoustical and visual output, such as for stimulus presentation, could be modulated by real-time analysis results, which enableded feedback and closed-loop experiments. Versions were available in English and German.
