Conclusions and Future Work• Design space for availability-sharing systems.• Analyzed the tradeoffs between Interrupters and Interruptees• Used the definition to propose a new system with three novel
contributions:– Multiple availabilities– Group-based Traceable-Asymmetry– Projector-based Information Delivery
• Long term deployment and improvements in the software, hardware and reasoning engine.
• Come see our demo.
