The much-anticipated 20th Annual South by Southwest (SXSW) has started on March 8, Friday, in Austin, Texas. The conferences & festivals presented offer the unique convergence of original music, independent films, and emerging technologies. Search giant Google always waits for this event. Last year the company created an entire village near the Convention Center. And this year, Google has opened a “playground” just outside the convention center and unveiled a “smart” shoe. The best thing of this shoe is it can talk!
