As injuries from pedestrian texting increase, Apple has filed a patent that could help those who can't tear their eyes from their smartphones, even if it means walking into lampposts or another distracted cell phone user. 

Apple's idea for 'transparent texting' accepts that texting while walking is a reality, but does not accept that it must be dangerous. The company's patent involves a video background instead of a solid color on the screen so that the user can keep an eye on the sidewalk while still sending messages or refreshing Twitter. 

A recent report from the University of Buffalo found that texting while walking may lead to more injuries per mile than distracted driving. London even somewhat comically padded its signs and lampposts to avoid distracted cellphone users from running into them, preventing physical injury as well as extreme embarrassment. 

Another study from Ohio State University reported that pedestrian emergency room visits involving cell phones tripled in just six years, although total pedestrian injuries decreased overall. In 2010, more than 1,500 people entered the ER for an injury caused by the distraction of a constant, irresistible stream of information and communication.

An obvious, costless solution could fully prevent pedestrian texting injuries—watch where you're going. Putting your cell in your pocket while walking could not only prevent injury, but also save the battery in cold weather and make you less of a target for rising cell phone thefts.
