  1. Home Media CentreSmart Interface School of Information Technologies University of Sydney Demonstration

  2. Research Problem • Develop an application to • Control a smart environment from a mobile device • Deliver personalised services to the user • Design and implement a smart environment for the Home Media Centre • Control a smart environment from an external location

  3. Motivation – Homer’s Smart Lounge Room • Homer’s Dream of a perfect lounge room • Wants to be able to control everything from a single remote • Wants his lounge room to remember what he likes and how he likes it • Homer wants to watch the baseball final but is out and can’t watch it. Homer has two options • Send an SMS to his Smart Lounge Room to tell it to record the final • Homer regularly watches the baseball and assumes his lounge room will automatically record it for him

  4. Background • Some work done on controlling Home Media Centres with phones • Various methods of connectivity used • Limited research on controlling other aspects of the environment • Not much work on personalisation of Home Media Centres

  5. Research Contributions • Demonstrated the use of a mobile phone as an interface for controlling a home media environment • Demonstrated the delivery of personalised environmental settings • Demonstrated the use of SMS to control an environment from an external location

  6. Architecture

  7. Freevo • Used to record and play television programs • Modified to send Elvin messages to environment on events that have occurred • Listens for Elvin messages from the interface (phone), SMS, and personalisation

  8. X10 Controllers • Listens for Elvin messages and executes the appropriate commands on the environment • Devices controlled using the electrical circuit they are connected to • HeyU application was used to handle the signalling of controllers through the electrical circuit.

  9. Smart Interface (Phone) • Developed a Java Application to run on a Nokia 6600 • Application had customized controls to the environmental elements • User commands were sent from the phone to the central server via Bluetooth • Central server forwarded all commands received from the phone as Elvin messages to other environmental components

  10. SMS • SMS Handler • SMS Listener • Gnokii • SMS Grammar [1] message = command channel [program] [date] time [2] command = “record” [3] channel = The TV channel [4] program = program_name [5] date = “today” | “tomorrow” | dd/mm/yyyy [6] time = start-end | start+duration [7] start = start time, 4 digits [8] end = end time, 4 digits [9] duration = duration, 4 digits

  11. Personalisation • The personalisation module provides three functions • Record programs most often recorded by users • Recommend programs recorded by similar users • Apply light and sound settings corresponding to a recorded program

  12. Demonstration ofImplementation

  13. Navigating Freevo Menu Right Menu Up Menu Left Menu Down Menu Select

  14. Controlling Lights Lights Off Lights On To dim lights select number between 0 and 23 then press lights on/lights off

  15. Watching TV Stop

  16. SMS Example Message Format: record 10 Simpsons today 1800-1830

  17. Personalisation

  18. Evaluation • Evaluated on 5 users • Tasks involved using the phone interface to navigate Freevo menus, control the lights and sounds, and send an SMS • All users successfully completed the tasks and within a reasonable time • Feedback generally positive

  19. Future Work • Scrutability for the assumptions made about the user’s environment preferences • General extension of the personalisation function supported • Introduction of additional applications and devices that the interface can control • Introduction of the notion of identity and presence through the use of device ID and X10 motion sensors in the environment

  20. Conclusion • Successfully demonstrated the use of a Mobile phone in controlling the Home Media Centre • Successfully demonstrated providing a personalised environment to the user • User evaluations found the interface to be appropriate
