Google Glass is one of the most outstanding inventions of mankind and has taken wearable computing to the next level. Though the high cost of the device has prevented it from taking off spectacularly, it is expected that the costs will go down as more companies enter the fray.
It works this way: when a user searches online for a particular product the click stream of searches he makes can be recorded to create a repository of intentions and that can be further analyzed to provide the right kind of targeted advertizing to users. When users search, they use a certain set of words to describe their needs to the search engines. If you are a savvy marketer, then you would definitely know that when a user searches a dictionary for the meaning of a particular word, he is not just finding the meaning of the word but finding a better word to express his emotions for which words are the only medium.
These set of words may not be always be grammatically correct but these are the keywords they will use to search for a particular product or service online. By recording this click-stream of searches, marketers can build a powerful database which can be leveraged to produce the right kind of marketing literature that has the potential to elicit the right response from users.
Search has been around for decades but it rose into prominence only when webmasters began to aggregate links of web pages and finding the right information became a challenge. Experts dealing with the internet began mining the web for more information and realized that the millions of page views that popular websites were experiencing can be mined for something more basic and contextual: What the world really wants?
By catering to this basic question scientists began indexing web pages that could be retrieved whenever a user asked for a web page with the similar name but the people in the search business had not yet found a way to make money until they found the answer in : CONTEXTUAL TEXT ADS. Cracking this puzzle meant opening up a Pandora box of revenues and text-ads which appeared on the left hand side of the search page based on the queries keyed in by the users became the juggernaut on which most search engines developed a model to survive.
