About

This Active Reading Assistant utilizes the Rapid Serial Visual Presentation (RSVP) method to eliminate saccadic eye movements, which account for approximately 65% of reading time. By presenting words sequentially at a fixed focal point, the brain can process information significantly faster than traditional scanning.

Unlike basic RSVP tools, this engine implements an Optimal Recognition Point (ORP) algorithm. It aligns the specific character of a word (the "foveal pivot") to the exact center of your visual field. This minimizes the time required for cortical recognition.

The system also employs Heuristic Timing Adjustment. It does not treat all words equally; the engine dynamically calculates exposure duration based on word length, punctuation (., ,, !), and semantic complexity, simulating a natural but accelerated cognitive rhythm.

Formulas

The delay interval T for each word is dynamically calculated based on the base Words Per Minute (WPM) and a heuristic multiplier M.

{

T = 60,000WPM × M

The multiplier M is derived from the linguistic properties of the token:

{

2.0 if token ends in { . ! ? }1.5 if token ends in { , ; : - }1.2 if length > 81.0 otherwise

The Optimal Recognition Point (ORP) index i_orp is determined by length L:

{

i_orp ≈ ceil(L × 0.35) − 1

Frequently Asked Questions

This is a feature, not a bug. The tool uses "Semantic Punctuation Heuristics". If every word were displayed for the exact same duration, your brain would struggle to process sentence boundaries and complex terms. We slow down slightly for long words and pause longer at punctuation marks (periods, commas) to allow for cognitive consolidation.

The ORP is the specific letter in a word where the eye naturally lands to recognize the word fastest. It is usually slightly to the left of the center. By aligning this specific letter to the fixed reticle on the screen, we reduce the micro-movements your eyes need to make, effectively increasing processing bandwidth.

Retention at high speeds requires suppressing "subvocalization" (the inner voice reading aloud in your head). Trust your visual cortex. Start at a comfortable speed (e.g., 300 WPM) and increase by 50 WPM increments only when you feel bored. If you lose track, use the "Left Arrow" key to rewind slightly.

Yes. The algorithm tokenizes text based on whitespace and standard Unicode punctuation. While the specific ORP calculation is optimized for Latin scripts (English, Spanish, French, German), the RSVP mechanism works effectively for any whitespace-delimited language.
