细节理解题。根据第六段中的“The new findings could improve the way human beings interact with their computers and other high-tech devices, even robots, allowing for more natural and realistic social interactions with machines.”（这项新发现可能会改善人类与电脑和其他高科技设备,甚至是机器人的互动方式，从而使人类与机器进行更自然、更现实的社会互动成为可能）可知，这一发现将改善人类和机器之间的互动。根据倒数第二段中的“People are always looking for improved, personalized services. Today’s robots and computers are not socially aware so they cannot adapt to non-verbal information”可知，人们总是在寻找改进的、个性化的服务。今天的机器人和计算机没有社交意识，因此它们无法适应非语言信息，故A项、B项、C项错误。故选D。
