Trail Buddy is a digital implementation of the Trail Making Test (TMT), a widely-used neuropsychological assessment for measuring visual attention, processing speed, and executive function. Run Part A (sequential numbers) and Part B (alternating numbers and letters) with randomized circle positions for a fresh experience every time. Key Features: - Two Test Modes: Part A for sequential number connection and Part B for alternating number-letter switching. - Configurable Difficulty: Adjust the number of circles (8–25) to suit different ability levels. - Millisecond Precision: Accurate timing and detailed tap data for every interaction. - Error Tracking: Automatic detection of incorrect taps throughout each session. - Data Export: Share detailed CSV results including all tap events and session notes. - Simple Interface: Whether your users are digital natives or have little to no tablet experience, Trail Buddy's intuitive design makes it accessible for everyone. Log name, age, sex, and notes for each session. Review your session history at a glance and export individual or multiple results for further review.
