Key Points

Develop a user-friendly application to streamline the scheduling and execution of time-managed protocols in human-subject research.
Created a GUI application using Python
Allows schedule creation in CSV format
Visualizes timelines and exports to SVG
Supports WAV alarms during protocol execution

Simplified planning and documentation of research protocols
Facilitated easy execution with visual timelines
Enhanced flexibility with rehearsal and restart capabilities

Abstract

Timeline-kun is a desktop Graphical User Interface (GUI) application for planning, executing, and documenting time-managed protocols in human-subject research. Schedules are defined in a simple CSV format editable in spreadsheet software, a text editor, or within the application, then visualized as a timeline and exported to Scalable Vector Graphics (SVG). The schedule can be executed as a timer that supports rehearsal or restart from an arbitrary stage. During execution, Timeline-kun plays WAV alarms and records logs in Brain Imaging Data Structure (BIDS) events.tsv format. It can also optionally control GoPro cameras over Bluetooth Low Energy (BLE). The software is implemented in Python and distributed as both a package and a standalone Windows executable.
