Healthcare providers, such as doctors, dentists, and nurses, have a critical need for information at the point of care. However, the point of care is often a constrained environment where common modes of interaction, such as touchscreens or keyboards are hard to use. A dentist, for instance, is always in a hands-busy mode when attending to a patient. Today, dentists need to either have all the information such as dental X-rays ready beforehand, or need to have a human assistant who can fetch the information when needed. This is an ideal scenario where a voice interface augmented by a display for the output becomes a highly desirable option.
