Hello from the other side! Is an physical computing interface exhibiting telepresence. The idea is to physically transmit a simple hand wave from User A to User B. An Arduino nano 33 IoT connected to an HC-SR04 takes hand waves as a input signal from User A transmits it over the Wifi using the ARDUINO NANO 33 with PubNub and sends it over to a remote User B, who has a Servo motor regulated hand which moves from 0 degrees to 180 degrees, upon receiving the signal from User A. This Servo is attached to the palm of the arm, which in turn moves as a waving hand. We further enghanced this project by adding a web cam to the palm of the physically computed hand at User B’s in order to make the telepresence more visual. The idea for this project was inspired by the Shape transmittance project conducted by MIT Media lab for Tangible interfaces. We took this idea of using a hand gesture and transmitting it, into a asimple handwave received as a signal from a User, and physically creating a computed hand at User B’send. In today’s times when people rarely meet each other in reality, let alone wave at someone, we felt that the relevance of a simple hand wave (physically computed) would be justified in today’s time and context, where people meet more often virtually.
How it works
Sheridan defined that telepresence is the ideal of the users to feel presenting at a remote site physically through the human operator .Objectively, telepresence extents humans’ feeling to a mediated environment through medium, rather than in the immediate physical environment .Draper introduces Synthetic Environment (SE), which purposes projecting the perceptual, cognitive, and psychomotor capabilities of the user into a distant, dangerous, or simulated environment, at the beginning of his essay on telepresence. Although both computer-mediated interaction and synthetic environment involve in human-machine interface design, SE subdivides into virtual reality systems, teleoperators, and telecommunications. Draper’s paper focuses onthe phenomenon related to the association of SEs and the term of telepresence, involving converting user’s self-perception into a computer-mediated environment . Based on the research on the SEs, Draper expended the definitions of telepresence into three aspects: the simple, the cybernetic, and the experiential. In the simple telepresence definition, it refers to the ability to operate in a computer-mediated environment, controlling machines over distance. The definition of cybernetic definition is that the index of the quality of the human-machine interface, for example, the operational characteristics of the human-computer-telerobot interface. In the experiential definition, telepresence means that a user feels physically present within a computer-mediated environment. Cybernetic telepresence focuses on projecting human capability into the computer-mediated environment, whereas experimental telepresence is the immersion of human consciousness into the computer-mediated environment .
The definitions of Teleoperator and Telerobot are the key to understand teleoperation. Teleoperator is a machine that enables the human operator to manipulate the distance objects through their capabilities . Simultaneously, Telerobot is a robot receives instructions from teleoperator over the distance. It usually has sensors and effectors for manipulation and/or mobility . Teleoperation is mean that using human intelligence to operate a robot with adequate human-machine interface in the distance. Usually, two robot manipulators are consisted by a teleoperation system. The master arm, one of the manipulators, is controlled by a human operator to generate commands to map the slave arm which is the remote manipulator . With the development of the Internet, the application for teleoperation become increasingly more extensive and indispensable. It had been used widely in hazardous and less structured environments such as space exploration, undersea inspection and maintenance, and toxic waste cleaning .
Our project is a simple telepresence example; through the 2-dimension screen, users are able to project a low level of vision on the remote site. At the same time, the shake hand movement detected by the distance sensor site can affect the movement of the hand (which attached a webcam) on the remote site. It is an example of teleoperation. While combining this two definitions into our project, the users can see the real-time video move during shake hand, toward a low level of immerse telepresence and teleoperation experiment. On the remote site, the user can see the hand move while others shake hand; this provides a scene of feeling the other site’s user on there.
