Procedural instructions and worked examples have been shown to be effective learning aids in science, technology, engineering, and mathematics (STEM) learning materials. Procedural instructions are texts that describe a general method to reach a goal, while worked examples demonstrate how to apply this method to a specific instance. Research supporting the use of advanced organizers predicts that if learners see the worked example first, they can develop a basis for the problem-solving procedure.
Washing hands is one of the easiest yet most effective ways to prevent spreading illnesses and diseases. However, not adhering to thorough handwashing routines is a substantial problem worldwide. For example, in hospital operations lack of hygiene leads to healthcare associated infections. We present WristWash, a wrist-worn sensing platform that integrates an inertial measurement unit and a Hidden Markov Model-based analysis method that enables automated assessments of handwashing routines according to recommendations provided by the World Health Organization (WHO).
There is a growing semi-automated fleet in the US, and the occupants of many of these semi-automated cars are frequently reading, working, watching movies, and even sleeping. To ensure safety and effective design of products, there is a need to examine the issues of: (a) the impact that being in the car has on performing non-driving tasks; and (b) the impact that performing non-driving tasks has on the person’s ability to re-engage in managing the vehicle’s operation. We are currently studying the task of using virtual reality in a vehicle, and its effect on situation awareness and trust.
Through this interaction we aim to see if doing physical movements in a virtual space, coupled with a peaceful environment, can help users destress. The interactor enters a mystical fairy land when suddenly he/she sees a flash of light hurling towards the ground. The flash of light injures one of the 5 fairies in the scene. The injured fairy falls down, upon being hit by the light, and can no longer fly. The other fairies in the scene ask for the interactor's strength to help them heal the injured fairy.
ZEUSSS or Zero Energy Ubiquitous Sound Sensing Surface allows physical objects and surfaces to be instrumented with a thin, self-sustainable material, giving rise to revolutionary applications such as interactive walls, localization of sound sources and people, surveillance via audio, contextualization and safer authentication services.
