Tachistoscope

Tachistoscope is a visual perception training and assessment app for education, therapy support, and research. It presents letters, words, images, and patterns at millisecond precision to train rapid recognition, attention, and reading speed. Core functions include fully customizable stimuli and exposure durations, adaptive difficulty and guided protocols, and real-time analytics with session history and export. Calibration tools help standardize screen size and viewing distance for consistent results. Designed for clinicians, educators, and learners seeking a research-inspired tool for cognitive training, vision practice, literacy drills, and experimental demonstrations.

1. Download and install the app, then grant required permissions as prompted. 2. Create a profile, run the screen calibration, and set your viewing distance following the on-screen guide. 3. Choose a goal such as reading speed, letter recognition, or attention, then select a preset protocol or create a custom one by choosing stimuli and exposure durations. 4. Start a session, focus on the fixation mark, and respond as instructed after each brief presentation; timing adapts based on your accuracy. 5. Review performance summaries, track trends over time, and export results; adjust difficulty, stimuli, or session length for continued training or assessment.
