Lane changing on highways is stressful. In this paper, we present RASCL, the Robotic Assistance System for Changing Lanes. RASCL combines state-of-the-art sensing and localization techniques with an accurate map describing road structure to detect and track other cars, determine whether or not a lane change to either side is safe, and communicate these safety statuses to the user using a variety of audio and visual interfaces. The user can interact with the system through specifying the size of their “comfort zone”, engaging the turn signal, or by simply driving across lane dividers. Additionally, RASCL provides speed change recommendations that are predicted to turn an unsafe lane change situation into a safe situation and enables communication with other vehicles by automatically controlling the turn signal when the driver attempts to change lanes without using the turn signal.

Computers and human beings play chess differently. The basic paradigm that computer programs employ is known as "search and evaluate." Their static evaluation is arguably more primitive than the perceptual one of humans. Yet the intelligence emerging from them is phenomenal. A human spectator would not be able to tell the difference between a brilliant computer game and one played by Kasparov. Chess played by today's machines looks extraordinary, full of imagination and creativity. Such elements may be the reason why computers are superior to humans in the sport of kings, at least for the moment. This paper article about how roles have changed: Humans play chess like machines and machines play chess the way humans used to play.
