iSphere
iSphere is an intuitive 3D modeling user interface using the information collected from the user to improve 3D modeling processes. iSphere is an input device for modeling 3D geometries through hand manipulation. This device is equipped with capacitive sensors that can respond the proximity of hand positions to 3D modeling systems. It allows users to manipulate 3D geometries using high-level modeling concepts like push or pull the 3D surfaces. By collecting proximity information between hands and input device, 3D systems are benefited to execute modeling commands proactively.
WaterBot: A Persuasive Technology to Motivate Water Conservation
Ernesto Arroyo
WaterBot is a persuasive water conservation device that presents “just-in-time” context-sensitive feedback to users. Its goal is to motivate behavior change regarding water conservation while using the bathroom sink. The system collects water usage information from flow sensors and presents subtle prompts at the point of behavior. These prompts are designed to be unobtrusive in the form of illumination, graph bars, and auditory feedback. WaterBot uses several persuasive techniques, such as law of contrast, positive reinforcement, variable schedule of reinforcement, social validation, scarcity, curiosity, and challenge.
