Systems, methods, and computer-readable media for managing collaboration on a virtual work of art between multiple electronic devices are provided. A first graphical display system of a first device may generate an input command in response to receiving user information through a user interface of the first device, and may then share this input command with a second graphical display system of a second device.

A multi-media method and system performs psychological assessment of an individual for suitability for particular jobs, whereby the individual is shown and provided with discrete visual and auditory stimuli on a multi-media computer screen, so that the individual's responses can be monitored in conjunction with physiological responses received by biofeedback sensors. The computer tallies the test subject's recorded responses. Virtual work environments are optionally displayed, to enable the tested individual to simulate a real work environment. Unlike other job evaluation systems, the system evaluates a job candidate's ability to maintain task focus under pressure. It directly measures performance under pressure, rather than only inferring potential performance based upon selective input from a job candidate.
