The creative project was twofold: Firstly, a large high speed DEC-10 interactive computer, located at Ball State University, was programmed, using FORTRAN language. The program is to be used by music students in real-time, on-line interactive classroom situations via a special teletype terminal located in the classroom. Secondly, a D17B mini-computer, located in the Electronic Music Systems Studio at Ball State University, was programmed using quasi-octal machine language for on-line, real-time interaction in conjunction with the ARP-2500 music synthesizer located in the same studio. This capability provides an adjunct to other compositional tools already available to the composer in this studio.The principal thrust of the software programs in both of these contexts was the on-line and automatic manipulation, handling, editing and control of pitch sets during interactive conversation with a computer via teletype or synthesizer keyboard. / School of Music

Direct interaction in virtual environments can be realized using relatively simple hardware, such as standard webcams and monitors. The result is a large gap between the stimuli existing in real-world interactions and those provided in the virtual environment. This leads to reduced efficiency and effectiveness when performing tasks. Conceivably these missing stimuli might be supplied through a visual modality, using sensory substitution. This work suggests a display technique that attempts to usefully and non-detrimentally employ sensory substitution to display proximity, tactile, and force information. We solve three problems with existing feedback mechanisms. Attempting to add information to existing visuals, we need to balance: not occluding the existing visual output; not causing the user to look away from the existing visual output, or otherwise distracting the user; and displaying as much new information as possible. We assume the user interacts with a virtual environment consisting of a manually controlled probe and a set of surfaces. Our solution is a pseudo-shadow: a shadow-like projection of the user's probe onto the surface being explored or manipulated. Instead of drawing the probe, we only draw the pseudo-shadow, and use it as a canvas on which to add other information. Static information is displayed by varying the parameters of a procedural texture rendered in the pseudo-shadow. The probe velocity and probe-surface distance modify this texture to convey dynamic information. Much of the computation occurs on the GPU, so the pseudo-shadow renders quickly enough for real-time interaction. As a result, this work contains three contributions: a simple collision detection and handling mechanism that can generalize to distance-based force fields; a way to display content during probe-surface interaction that reduces occlusion and spatial distraction; and a way to visually convey small-scale tactile texture.
