I have a reader app for my smartwatch that works this way. Only downside is you have to have whatever you want to read in limited formats (ePub, PDF, Docx, and text) for the reader.

Wear Reader is free and does ePub and PDFs. It supports speed reading with adjustable WPM.

Such an app does exist for Android Wear. I haven't gotten the chance to test it myself, but it looks promising.
Are there any good "spritz for wear" apps? Anybody using this: https://play.google.com/store/apps/details?id=com.jacoh.wearreader&hl=en ?
