lame the Facebook app or Angry Birds, but people are forgetting their etiquette when their mobile devices are in tow, according to a survey commissioned by Intel.

Nine out of 10 adults in the US claim they have seen people “misuse mobile technology”, the survey found. And 75% of the respondents said mobile manners are worse now than it was in 2009. Among the “pet peeves” identified in the survey include texting or typing while driving, talking on a device loudly in public places and using mobile devices while walking.

The mobile zeitgeist, in which a large majority of American adults are connected on-the-go, has led to more “public displays of technology”, Intel said. While respondents were able to identify lapses in mobile etiquette, 19% of them admit they continue thumbing their iPhones or BlackBerrys because “everyone else is doing it”, according to Intel.

“Smartphones, tablets and other mobile devices are really still in their infancy, so it’s no surprise that people still struggle with how to best integrate these devices into their lives,” Intel head of interaction and experience research Genevieve Bell said in a statement.

“New digital technologies are becoming a mainstay in consumers’ lives, but we haven’t yet worked out for ourselves, our families, communities and societies what all the right kinds of behaviors and expectations will be.”A total of 2,000 US adults aged 18 and above were polled to arrive at the findings.
