  1. Aibo companion DOAS – group 1 Aitor Azcarate Onaindia Abeer Mahdi Zhiwei Zhan Ning Yang Supervisor: Frans Groen

  2. Introduction • In the future more help is needed for elder care. • The solution is to make use of intelligent home with intelligent agents for interaction : for example Aibo • We looked at the possibilities of Aibo as elder companion • We implemented some interesting tasks. (mentioned later)

  3. Tasks that should be realized by Aibo for elderly care 1.Sensing intelligence -Follow the elder -Detect when a person is falling down -Detect location 2. Communication intelligence -interaction with persons and nurse -interface with home equipments like tv. 3.Emotional intelligence -Face feature recognition -Initiate a conversation -Inactivate mode -Pro-active suggestions -Reaction to sound

  4. System Architecture

  5. Literature study • Following the elder, algorithms that can be used are: • Mean-shift algorithm • Optical flow motion • Sound direction detection • A combination of the above • Localization of Aibo • ‘map using’ methods • Appearance-based methods • Face recognition • Performance being evaluated • Aibo in the future • As the universal interface to the home equipment

  6. Tasks implemented We chose basic functions that can be extended in the future. • Reaction to sound • Make Aibo react to voice commands, by performing specific tasks • Face detection • When seeing a face Aibo walks to the face and sits down • Pink Ball tracking • Make Aibo look for a pink ball and walk to it.

  7. Available tools • Development tools • Openr SDK (c++ programming) • Tekkotsu (c++, java and matlab) • Remote framework (combined with visual c++) • R-code (script language, which we used) • Graphic user interface • Motion editor (creating new motions for Aibo) • Control panel • Sony entertainment player (control Aibo)

  8. Reaction to sound • Aibo has a predefined voice command recognition list of 54 voice commands • We implemented some reactions to certain voice commands, some of these reactions are motions and others are voices that we recorded. • We experimented with Sony motion editor to create new motions, but we noticed that it doesn’t support Aibo ERS-7 very well.

  9. Results • We noticed that Aibo sometimes cannot recognize the voice command correctly, despite the distance of the speaker. • --Demo

  10. Face detection • R-Code has a predefined function for face detection • We implemented Aibo to detect a face, if found, Aibo will walk to it and sit down

  11. Results • Aibo can detect faces correctly. • However, in this stage it can only detect the front side of the face. • --Demo

  12. Pink Ball tracking • R-Code has a predefined function for searching the Pink ball • This can be extended to follow the elder in the intelligent home

  13. Result • The results are not accurate, this is because the basic functions are not accurate, for example the walk function. This can be caused by the physical construction of Aibo • Aibo can follow the pink ball correctly for an average of 4 times, after that it losses the ball. • The closer the ball is, the less chance of finding the ball.

  14. Result (2) • --Demo pink ball

  15. Conclusions • why we chose R-code • Simple script language to learn in a short time • Compact compared with for example Java, which take 400 lines of code to make Aibo nod it’s head (with R-code it is a few lines) • After experimenting with R-code, we noticed the following • It is not an open source, that make it not extendable • It is not suitable for low level programming or academic use • The predefined functions are not very accurate

  16. Conclusions (2) • Aibo is currently not capable of being the companion for the elders • It is a nice entertainer but not really suitable for critical circumstances • it would be more capable if aibo can interact with medical aids like nurses in the hospital • The things that should be done to make Aibo more suitable are • Extend the voice recognition list • Improve the basic functions (e.g. walking) • Make a good API
