No Smoking Please - a wearable persuasive computing device

  1. 1. A Persuasive Computing Device Amulet to Quit Smoking A Preliminary Design Presentation by Piotr Kulaga desc9179 – Semester 2, 20073 Oct 07 AMULET TO QUIT SMOKING by Piotr Kulaga - desc9179 Ambient Visualisation with Devices 1
  2. 2. Amulet to quit smokinga wearable persuasive device Objectives Aid the user in the effort to quit smoking cigarettes. Employ methods which operate in a subtle manner, imposing only a minimum of burden and annoyance. Means Utilise Persuasive Computing technology to moderate the habitual smoking routines. Implemented as a wearable device interacting with the user.3 Oct 07 AMULET TO QUIT SMOKING by Piotr Kulaga - desc9179 Ambient Visualisation with Devices 2
  3. 3. Persuasive ComputingmethodologyA combination of technical & theoretical techniques aiming to;  Promote intrinsic motivation through self-reflection.  Avoid nagging, punishment or coercion.  Focus on novelty and surprise to induce the desired effect.  Target the user behaviour when it occurs and the intervention is most effective.3 Oct 07 AMULET TO QUIT SMOKING by Piotr Kulaga - desc9179 Ambient Visualisation with Devices 3
  4. 4. Persuasive Computingmeans of persuasion Monitor, analyse performance and act to influence the user behaviour in real-time. Use timely, appropriate to the situation and subtle feedback. Employ infrequent and brief sound sequences. Consider the social impact and context of the device in operation.3 Oct 07 AMULET TO QUIT SMOKING by Piotr Kulaga - desc9179 Ambient Visualisation with Devices 4
  5. 5. Persuasive devicethe mode of operation The user interacts with the wearable device in everyday life. An ambient personal device. Feedback is ambiguous and exhibits random behaviour. The user interprets the interactions and reflects on the goals and their performance. The device can also interface with a PC. A non-critical element of operation for activity analysis and expansion.3 Oct 07 AMULET TO QUIT SMOKING by Piotr Kulaga - desc9179 Ambient Visualisation with Devices 5
  6. 6. Persuasive devicethe logical process flow A physical sensor detects user actions. The signal is analysed to recognise smoking events. By comparison to typical and extreme performance criteria. Some reasoning is performed regarding; User’s performance. Possible context of a given situation. (Previous interactions.) Appropriate mode of intervention. Aural feedback is provided to the user. Sound clues symbolising positive and negative states are presented.3 Oct 07 AMULET TO QUIT SMOKING by Piotr Kulaga - desc9179 Ambient Visualisation with Devices 6
  7. 7. Device development [1]sensor experiments The initial experiments employed a photoelectric smoke detector. Which often failed to detect the targeted activity. The PIR sensor advantages; sensitivity, selectivity, adaptability to other activities.3 Oct 07 AMULET TO QUIT SMOKING by Piotr Kulaga - desc9179 Ambient Visualisation with Devices 7
  8. 8. Device development [2]sensing the targeted behaviour PIR sensor – the principles of detection.3 Oct 07 AMULET TO QUIT SMOKING by Piotr Kulaga - desc9179 Ambient Visualisation with Devices 8
  9. 9. Device development [3]feedback sound clues Sounds revoking nature are used. Bird, cricket, cicada and heavy breathing. Random and periodic signal fluctuations combine to generate simple sounds.3 Oct 07 AMULET TO QUIT SMOKING by Piotr Kulaga - desc9179 Ambient Visualisation with Devices 9
  10. 10. Amulet designconcluding observations The physical characteristics of the amulet may have a limited appeal. Blokes While the device operates primarily in a standalone mode, the PC interface allows for updates and evaluation of the collected data. New sound synthesis programs. The system software can be adopted to address other behaviour modification problems. Providing similar physical characteristics, eg fingernail biting.3 Oct 07 AMULET TO QUIT SMOKING by Piotr Kulaga - desc9179 Ambient Visualisation with Devices 10
