With endless applications, high-speed wireless Internet access, and free messaging services, smart phones have revolutionized the way we communicate. But at what cost? According to researchers at Tel Aviv University, the smart phone is challenging traditional conceptions of privacy, especially in the public sphere. Dr. Tali Hatuka of TAU's Department of Geography and Dr. Eran Toch of TAU's Department of Industrial Engineering have teamed to measure the impact of the smart phone phenomenon on privacy, behavioral codes, and the use of public space. Their early results indicate that although spaces such as city squares, parks, or transportation were once seen as public meeting points, smart phone users are more and more caught up in their technology-based communications devices than their immediate surroundings.

Smart phone users are 70 percent more likely than regular cellphone users to believe that their phones afford them a great deal of privacy, says Dr. Toch, who specializes in privacy and information systems. These users are more willing to reveal private issues in public spaces. They are also less concerned about bothering individuals who share those spaces, he says.

Inside a private bubble

Dr. Hatuka says that smart phones create the illusion of "private bubbles" around their users in public spaces. She also believes that the design of public spaces may need to change in response to this technology, not unlike the ways in which some public areas have been designated as "smoking" and "non-smoking." Dr. Toch also notes that smartphones and personal computing devices are becoming more "context-aware," adjusting themselves in terms of brightness and volume to the user's location and activity.

To examine how smart phones have impacted human interactions in public and private spaces, the researchers designed an in-depth survey. Nearly 150 participants, half smart phone users and half regular phone users, were questioned about how telephone use applied to their homes, public spaces, learning spaces, and transportation spaces.

While regular phone users continued to adhere to established social protocol in terms of phone use -- postponing private conversations for private spaces and considering the appropriateness of cell phone use in public spaces -- smart phone users adapted different social behaviors for public spaces. They were 50 percent less likely to be bothered by others using their phones in public spaces, and 20 percent less likely than regular phone users to believe that their private phone conversations were irritating to those around them, the researchers found.
