Tablets with paper-thin screens that can be folded and tucked into your back pocket, artificial intelligence and augmented reality — the stuff of science fiction may be coming to a store near you. Some researchers are experimenting with wearable devices, such as Google Glass, a stamp-sized electronic screen mounted on eyeglass frames to record video, access email and surf the Web. Others, like Microsoft, are investigating the use of 3-D cameras to create images that pop up when a person calls. Samsung has a concept video that shows a bendable, transparent 3-D smartphone-hybrid tablet that can also be used as a real-time interpreter. Few of these new technologies will hit store shelves any time soon - companies and researchers are more actively working on touchscreen innovations in the near term.

San Francisco has the best city park system in the United States along with Sacramento, Boston and New York, according to a ranking of the 40 best systems across the country. Cities on the east and west coasts dominated the top 10. Parks in the west coast communities of Portland, Seattle and San Diego made the cut. The east coast’s Virginia Beach and Philadelphia also ranked high on the list. The rating system looked at the percentage of residents living within a 10-minute walk of a park, the proportion of local land dedicated to parks, and the number of playgrounds and spending per capita on systems. Southern cities dominated the 10 park systems with the lowest scores. Charlotte came in after Fresno, followed by Louisville, Kentucky. Jacksonville and Memphis also scored low marks.

Josh Buckley, chief executive of an online gaming start-up, is looking forward to next month’s Game Developers Conference in San Francisco, particularly for the parties and the accompanying schmoozing with industry A-listers. There’s one problem: Buckley, who will turn 20 this week on February 22, may be turned away from many of the parties because he is not old enough to drink. His fake ID was recently confiscated, and the two new ones he ordered from a company in China have not yet arrived. Such are the dilemmas facing the ever-younger entrepreneurs that Silicon Valley investors are backing these days. While little data on the phenomenon exists, venture capitalists say they are funding more chief executives under age 21 than ever before. Read more: Meet the adolescent CEOs of Silicon Valley
