During my Master of Science thesis, under the supervision of Dr. J. Antonio Garcia Macias, my research topic evolved from navigating augmented spaces with scenario-based applications to a complete general-purpose browsing system for the Internet of Things. This browser was called the ‘Sentient Visor’.

Information heterogeneity becomes a problem for a user trying to consume data from augmented objects. Having a dedicated application and asking a user to install a particular software for each type of object would be undesirable. To avoid this situation, we proposed a design space to develop sentient visors that allow browsing the information space in the Internet of Things, consisting of six design dimensions:

  • contextual reasoning
  • context awareness
  • mixed-reality UI
  • multimodal information
  • object ID/discovery
  • semantic communication.

I implemented a Sentient Visor system prototype capable of searching, identifying and communicating with smart objects nearby. The system allows a user to consume web services provided by smart objects without requiring previous knowledge of the services provided or technologies embedded in the object.
