theodp writes: A newly surfaced Microsoft patent application, reports GeekWire, describes a 'user-following engine' that analyzes your posts on Facebook, Twitter and other social media sites to deduce your mood, interests, and even your smarts. The system would then automatically adjust the search experience and results to better match those characteristics, explains Microsoft, such as changing the background color of the search interface to suit your mood, or bringing back only those search results that won't strain your feeble brain. From the patent application: 'In addition to skewing the search results to the user’s inferred interests, the user-following engine may further tailor the search results to a user’s comprehension level. For example, an intelligent processing module may be directed to discerning the sophistication and education level of the posts of a user. Based on that inference, the customization engine may vary the sophistication level of the customized search result.' So, is this the same technology the Microsoft Store used to determine I'd need a $49-an-hour Microsoft "personal trainer" to grasp Windows Live Photo Gallery, the same software that 4-and-a-half year-old Kylie mastered on her own?
