I was reading Scoble’s post about Windows Live Search and I realized what the future of search is going to look like (or so I think). I realized that the users don’t know how to express in a written way what they are looking for. Most of the times, you type a couple of keywords that should, theoretically, yield some results from which you can identify the one you are looking for. Human powered search engines like Mahalo have the same problems. They rely in human beings building pages with the most relevant information about a topic, but if you are looking for something not that common you’ll run into problems. Last but not least, semantic search engines like Powerset are closer to the goal, but there is still a big hurdle in the user’s way. How do you phrase, as a user, the information you are looking for? You need to type a phrase, but it’s not that obvious what that phrase should be, making it hard and slow to search things.
Now, the big problem again is writing down what are you looking for in a way the search engine understands it. How about another approach? How about a search engine that reads your mind so that it knows what you are really looking for? Most readers must have had a good laugh with the former statement but I have to say that mind reading devices are a big reality with their own field of expertise called Brain – Machine Interfaces (BMI). Several gaming companies are already using these devices to allow their players to control virtual avatars with their minds.
And how do these devices work? Generally speaking, it’s a helmet that reads neuron impulses in several areas of your brain. In the gaming example, they read the brain areas dedicated to movement, mapping neuron firing patterns to an specific movement in the game. This technology is still giving its first steps in the commercial arena, but I’m pretty sure we’ll see more and more devices working with it.
Now, is it a big stretch to say that we can use similar devices to read our search intentions? It is indeed, it’s something that is still out of reach. Not because of technology but because of a lack of Neuroscientific data that can be use to pinpoint which brain areas we use when searching online. But it’s just a matter of time (I’m talking about 5 to 10 years here).
Big problems with this type of search, you not only need a web index, but a neuron firing pattern index and an engine to understand them and translate that into a web search query. Another big issue is brain privacy. Your neuron firing patterns would need to be transmitted through the Internet and stored somewhere. That’s a source of major privacy concerns that should be address before using a search engine like this.
Nevertheless, and with all the problems than might arise with an idea like this, I truly think we’ll someday see something like this and I have to say it will be awesome. I don’t know if any company is currently investing in developing a mind controlled search engine, but it would be a great project for a big company like Google, IBM or Microsoft.
Do you like the nextgen search engine? What problems do you see with it? Would you use something like that?
