  1. 1. How smart are our environments?An updated look at the state of the art 學生:徐欣佑
  2. 2. Introduction <ul><li>Define a smart environment as </li></ul><ul><ul><li>Able to acquire and apply knowledge about the environment </li></ul></ul><ul><ul><li>Can adapt inhabitant's preferences and requirements to improve their experience </li></ul></ul>
  3. 3. The type of experience that individuals wish <ul><li>Safety of inhabitants </li></ul><ul><li>Reduction of cost of maintaining the inhabitants </li></ul><ul><li>Resource optimization(energy or bandwidth) </li></ul><ul><li>Task automation </li></ul>
  4. 4. The components of a smart environment <ul><li>Perception of the environment is a bottom-up process </li></ul><ul><li>Action execution flows top-down </li></ul>
  5. 5. Technologies <ul><li>Smart devices and embedded systems </li></ul><ul><ul><li>Sensors,controllers </li></ul></ul><ul><li>Wireless mobile communications </li></ul><ul><ul><li>Wireless LANs, ad hoc sensor network </li></ul></ul><ul><li>Computing paradigms </li></ul><ul><ul><li>Distributed,grid computing </li></ul></ul><ul><li>Middleware </li></ul>
