Boggle is an award-winning brain-controlled web browser that redefines internet access for people with severe motor impairments. Powered by neural responses to visual stimulation (Steady-State Visually Evoked Potentials), it enables users who cannot rely on traditional assistive technologies, such as eye trackers and switch control, to navigate the web freely.
Boggle is developed as part of the BrainWeb project, and it contributes to ongoing research as well as practice in the field of assistive technology.
Boggle is designed to work outside the lab and developed for people who cannot use traditional assistive technology. Using Steady State Visually Evoked Potentials (SSVEPs) and accessible EEG hardware, it brings reliable, low-cost brain-computer interaction to the web, enabling access to the internet for all, without limitations.
Discover all the features built into Boggle.
Generates SSVEP stimuli for Boggle using an in-house library developed for SSVEP brain-computer interfaces.
The algorithm efficiently segments the screen into regions, automatically detects interactive elements, and highlights them for easy selection by the user.
Supports interaction with buttons, links, checkboxes, radio buttons, text fields, numbers, dates, comboboxes, videos, audio, and more.
Compatible with multiple EEG headsets so that users can utilise any headset they prefer.
Features an 18 stimuli keyboard with autocomplete, a minimised keyboard designed to reduce the number of simultaneous flickering stimuli, and a numeric keyboard for efficient text and numeric entry.
Manage bookmarks and tabs efficiently with intuitive controls for saving, opening, closing, and switching between web pages.
A settings page that offers extensive customisation options to tailor the user experience according to individual preferences.
An optional adaptive switch support which reduces on-screen flicker to lower cognitive load and improve selection accuracy.
Explore our first research paper which demonstrates how standard web technologies like CSS and WebGL can be used to generate stable, accurate SSVEP stimuli directly in a browser.
