Human spatial activity is often governed by limitations, and not by independent decisions by spatially or temporally autonomous individuals.
It is the theory of space-time path provided by Torsten Hӓgerstrand in the 1970s. He observed the human migration patterns related to the times. He observed the human migration patterns related to the time and the person’s own situation. He was convinced that the human beings as groups and aggregate populations masked the true nature of human patterns of movement. But the human migration limited or constraints by the three categories: capability, coupling, and authority.
Capacity constraints refer to the limitations of physical or biological factors on human motion. Which mean a person cannot be in two places at the same time or travel instantaneously from one location to another. In other words, we must make a certain trade-off between space and time.
Coupling constraints refer to the need to be in a specific location at a specific time, usually interacting with other people. This coincidence of space-time paths is described as “bundled” paths in a station’s tube. Your space-time path must be temporary connect to other people’s space-time paths to accomplish specific tasks. This could mean anything from home to go to college for a day.
Authority constraint is the area (or “domain”) that is controlled by certain people or institutions by setting access restrictions on their particular individuals or groups. Such as a person’s space-time path is normally not permitted to enter a sensitive military base or private club.
Throughout the Torsten Hӓgerstrand’s theory of space-time path, we realize about our human spatial activity are limitation and constraints from the capability, the coupling, and the authority. It affects the amount of time we spend dealing with everything in our lives. We have not allowed doing two things at one time.
Our complaints about the limitations of time constraints on our spatial activity prompted us to develop a systematic Internet now. The system Internet as a media of the new era, allows us to handle many things at the same time in our lives. Our spatial activity and the time being unrestricted as the Internet media assist us to manage time. During the work, we can transfer the information to two different people by email and speak to other at the same time and in the specific location. Human spatial activity and the time are gradually under control by people own.
Where am I now?
I am in the specific classroom listening to the Dr.’s talk to us. I am viewing my facebook and typing my blog post. The right next to me is using the WhatsApp web to text her friends for discussing how to write the blog post and watching the Korea program at one time. Some student is watching the movie. Most of the others are busy at writing the blog post layout. Our spatial of the activities are fixed but our activities are the difference but it all happen at the same time. We have achieved doing everything we want without the limitations or constraints from capability, coupling, and authority. This is a proof of what Torsten Hӓgerstrand told us the possibility to improve the human spatial activity and the time limited.
