The SoProMon project (Sonification for Process Monitoring) investigates how to best support users in the real-time monitoring of processes by presenting process-relevant data using both visuals and audio. The project is being carried out as a joint cooperation between the research groups Workflow Systems and Technology and the Ambient Intelligence Group at CITEC/Bielefeld University, Germany (https://www.cit-ec.de/en/ami).

As process monitoring is a task that is often performed in parallel to other tasks, we specifically investigate the usage of sonification, the presentation of data as (non-speech) sound, to enhance current visual-based monitoring approaches. Auditory alerts and alarms are already in use in many control centers but come with several drawbacks, such as the possibility of so-called "alarm floods", in which operators do not take alarms as seriously as they are or ignore them altogether due to an excessive amount of occurring alerts.

However,  apart from simple auditory cues, more complex sonifications are capable to represent continuous values by mapping data to auditory features of sound, such as pitch, level, duration, timbral characteristics, brightness, roughness or spatial location of sound events in a stereo or multichannel display.

The SoProMon project thus aims at investigating into the usage of sonification to enhance current visual process monitoring systems for a),  its application in control centers, such as e.g. in  

  • Industrial production and logistics
  • Power Plants
  • Road traffic or Mass Transit Control Centers  

but also for b), areas that typically do not feature full-time monitoring personnel, but rather employees that need to monitor processes in parallel to their main work, such as e.g.  

  • Office clerks that need to monitor administrative processes, such as e.g. insurance claims
  • Managers and supervisors that want to keep an overview over their business processes
  • IT administrators that monitor e-commerce processes or need to be informed about potential network intrusions  

The SoProMon project specifically tries to answer the question which kind of sound-assisted monitoring is best suited for what kind of usage scenarios, as well as how different types of sound-enhanced process monitoring attract and direct attention and concentration. To reach these goals, we will  

  • develop specific methods for specific information types
  • develop tools for their integration into practical multi-modal monitoring scenarios
  • evaluate of their effectiveness, acceptance and utility to organize a user’s focus of attention

Sonification for Process Analysis

Besides real-time process monitoring, sonification also lends itself to the retrospective analysis of process execution data.
We have developed a ProM plugin for multi-modal process data analysis to investigate the potential of sonification in this domain.
