wtf is lume?

Lume turns Rokid AR glasses into a wearable speed reader. It works using a technique called RSVP, short for Rapid Serial Visual Presentation, where text is shown one word at a time at a fixed point in your field of view instead of scrolling across a line. A single letter in each word is highlighted so your eyes lock onto that spot and never have to scan back and forth. Reading speed starts around 350 words per minute and can be pushed up to 700. The project is a paired two-app system. A phone app acts as the reading library: you can add PDF and TXT files, paste in text directly, or share text and PDFs into it from any other Android app using the normal share menu. All text extraction happens on the phone itself, nothing is sent anywhere else. The phone then streams the text to the glasses over Bluetooth in small word-by-word chunks. On the glasses side, a simple display shows the reading. Tapping starts or pauses the current document, and swiping changes speed while reading or steps sentence by sentence while paused. When paused, the surrounding sentence is shown with the current word highlighted so you can find your place again. Reading progress is saved automatically for each document and picks up where you left off, even after reconnecting the glasses. Other touches include adaptive pacing that holds longer on long words and sentence endings so fast reading stays comfortable, a bilingual English and Portuguese interface, and a connection system that tries several Bluetooth methods at once and keeps whichever connects first, reconnecting automatically if the link drops. The project has a public backlog of planned features including EPUB support, importing readable text from web articles, chapter navigation, bookmarks, and reading statistics. There is no packaged release yet. Building it requires Android development tools including a JDK and the Android SDK, and the resulting apps are installed manually onto the phone and sideloaded onto the glasses. It is released under the MIT license and is written in Kotlin.
