University of Toronto WearComp Linux Project
Much work remains to be done in development of this project. Currently, I teach Electrical and Computer Engineering (ECE1766) at the University of Toronto. To the best of my knowledge, this is the world's first course on how to be a “cyborg” entity. Students learn not only by doing, but by being. I call this form of learning existential learning. Each student creates a “reconfigured self”--a new form of personal space. Thus, students learn about the concept of personal empowerment from a first-person perspective through personal involvement.
We are writing new protocols for the altered perception of reality (mediated reality) that the WearComp provides. One example is picture-transfer protocol (PTP), in which packets of variable length are transmitted. Each packet is a JPEG compressed picture. Because of image compression, the amount of data varies depending on image content, hence the packet length depends on image content.
The reason for one packet per picture is that pictures are taken 60 times per second, which is much faster than they can be sent. Thus, whenever there is a lost packet and a re-transmission is needed, a newer picture will most likely be available to be sent instead. With PTP, retransmissions are always current.
Next month I will describe a mathematical (computational) framework called “Mediated Reality”, in which we will see that picture data is of greatest value only if it is up-to-date. Old pictures are of less value when trying to construct a computer-mediated reality. Thus, packet resends should always be of the most current image; hence the design of PTP is based on variable packet lengths, in which the packet length is the length of a picture.
