Introduction
In research, precision and context are essential. Knowing not just when activity occurs, but also what triggers it or when specific behaviors happen, adds valuable depth to data. The Fibion Krono device offers an event marker button, allowing participants or researchers to record specific activities or transitions in real time. This simple yet powerful feature enhances the accuracy of data by linking key actions directly to timestamps, creating a layer of context that is particularly valuable in studies of sleep, circadian rhythms, and behavior.
With the event marker, participants simply press a button on the wrist-worn device, avoiding the hassle of using a smartphone app. Unlike mobile applications that require setup, syncing, or potential distractions, Krono’s event marker enables participants to easily log events with minimal interruption to their routines. This streamlined approach not only increases adherence but also improves the reliability of data by capturing moments as they occur.
What is the Event Marker Feature?

The event marker on Fibion Krono is a button integrated into the device, designed to make contextual data logging effortless. With a simple press, participants can log specific events in real time, such as when they go to bed, wake up, or begin certain activities. This immediate recording adds valuable context to baseline measurements, creating timestamped data that aligns specific actions with environmental and physiological data.
For researchers, this feature opens the door to more flexible study designs, as it enables event-based tracking without relying on external devices. By pressing the event marker, participants can add context directly into the data stream, eliminating the need for additional setups like smartphone apps, which require installation, syncing, and frequent interactions. This simplicity not only enhances participant adherence but also ensures more consistent and reliable contextual information.
Benefits of Event Logging in Research
The event marker feature brings several benefits to research studies by adding precision, flexibility, and ease of use:
- Increased Data Accuracy: By allowing participants to log events as they happen, the event marker improves the precision of behavioral data, linking specific actions to environmental conditions, movement patterns, and physiological metrics.
- Customized Data Collection: The flexibility of the event marker makes it possible to design studies that rely on specific, time-stamped behaviors. Whether marking times of meals, periods of rest, or moments of heightened activity, researchers can customize data collection to suit their study’s unique requirements.
- Improved Participant Adherence: Using a wrist-worn button instead of an external app minimizes participant burden, making it easier for them to log events consistently without interruption or distraction.
Practical Applications of the Event Marker Feature
Fibion Krono’s event marker enables applications across various fields by allowing researchers to log actions and transitions that are relevant to their studies:
- Sleep Studies: Participants can press the event marker when they go to bed and when they wake up, providing researchers with precise sleep and wake times that enhance sleep duration and quality assessments.
- Behavioral Studies: By marking specific activities like eating, social interactions, or exercise, researchers gain a timestamped log of behaviors that can be correlated with physiological or environmental data.
- Circadian and Activity Studies: Event marking allows for the tracking of transitions between activities, rest, or sleep. This data provides researchers with context about participants’ routines, which can be analyzed alongside light exposure, temperature, and movement data to better understand daily patterns and rhythms.
Future Applications for Data Customization
Fibion Krono’s event marker also lays the foundation for advanced analytics and data customization. By enabling researchers to collect time-stamped data, this feature supports future applications in machine learning and behavioral modeling. Researchers can leverage event-based data to develop custom algorithms that identify patterns and assess behaviors in more detail than standard analytics allow. As research methods evolve, having this feature in place ensures that Fibion Krono remains adaptable for innovative study designs.
Conclusion
The event marker feature in Fibion Krono provides a simple yet powerful tool for capturing real-time contextual data, enhancing the depth and precision of research across sleep, behavioral, and circadian studies. By simplifying event logging, it enables participants to add meaningful context to their data without the hassle of external devices. For researchers seeking both accuracy and flexibility in study design, the Fibion Krono event marker represents an invaluable asset for conducting comprehensive, data-rich research.
