The portable spatial information technologies sketched in this paper do not yet exist. While they may sound like fiction, they are pretty realistic goals for the next 5-10 years. In order to make them reality, however, two types of advancements are needed. First, technological advances. They include improved quality of displays of hand-held devices (e.g., larger screens, foldable screens, readability under sunlight), more stable and much higher-bandwidth wireless communication, and low-cost GPS and gyroscope cards. These hardware technologies are developing rapidly and we foresee little impediments for them to become available as the basis of our family of portable spatial information technologies. The second area in need of advancement is know-how. In order to design successfully portable spatial information technologies, we need better knowledge about human-computer interaction, including how people work in the field, how they perceive geographic space, and how the new technologies influence their working habits. These new devices will need to make predictions about human behavior and performance as their users perform spatial tasks.
