Jonathan DiCarlo has been writing a series of blog posts discussing language-based interfaces — interfaces that allow you type commands in real language and the right stuff happens. “What would the web be like if you could tell it what you want to do as easily as you currently tell it where you want to go?”

Mozilla Labs has started experimenting with linguistic interfaces that are designed to do just that, the first of which is the recently-launched Ubiquity project. Jonathan’s posts are an extensive look into the concepts, questions, and thinking behind the experiments, and he has written three so far: Language-based interfaces: The problem, Language-based interfaces: Where do we stand now?, and Language-based interfaces: Report card for Ubiquity. If you’re at all interested in these approaches and ideas you should read Jonathan’s blog, and then head over to the Ubiquity project to get involved with the growing community working on these experiments.

Aza Raskin writes, “For the third installment of the Firefox Mobile design discussions, it’s bookmark time. Bookmarks have been a fundamental feature in the browser since Mosaic days. Do they have a place in Mobile? Are there better paradigms? How are they displayed? What’s the difference between a tab and a bookmark? Is it only a matter of one being in the device’s memory?” These are some of the questions that are asked and answered in the third video installment of the Firefox Mobile design sessions. Aza and Madhava look forward to your thoughts and feedback. More information is available at Aza’s weblog.
