Discussion with Paddy and Davide 2nd Feb 2010

February 2nd, 2010 Leave a comment Go to comments

Met with Paddy and Davide and discussed what we have been doing.

  • Actions from last meeting:
  • Said that I had been collecting data which seems to have good location information.
  • Had spoken with prag etc. but not really very useful
  • Davide has come up with some great questions for analysis of data
  • The only thing I hadn’t done was arrange a presentation for findings so far.

Paddy was happy with the progress so far, and after we discussed a number of things, we came to the following action points:

  1. Do a quick and dirty analysis of data
    1. Mobility analysis
    2. Periodicity
    3. Buddys
    4. Spatial degree
    5. Situation detection e.g. what does periodiciy mean?
  2. This is so that we can ask:
    • Do we have the data we need already?
    • What are the limitations of the data?
    • Are there other questions we need to ask?
  3. Plan a presentation for next wednesday morning (more of a brainstorm) to develop the ideas further, and really try to hammer down the larger plan

Paddy also suggested that we think about putting a paper into ubicomp (deadline 13th March) about our analysis of this data, but put a spin on it, e.g. what does periodicity mean? Can we predict events based on this? – Can we infer some useful context, based simply on the structure of the data, without the need for advanced techniques ( – i call this Urban Guerilla Sensing).

We suggested that we might be able to do two applications based on one of buddy finding analysis part (see mobile_agents and PhD the Story) the first, Paddy dubbed F3 (Facebook Friend Finder) where we encourage people to collect data for us, in return for detecting the presence of other facebook users, and suggesting friends based on frequency of co-location. The second was a similar application, but for regular visitors to research seminars.

I mentioned my vision on the next three points of reference, the first being a paper about the collection and analysis of this dataset, the second being another work which tied this into an simulator for the dataset, which synthesises this data in to a generic set, which can be used to test MANETs etc. The final thing (I didn’t get this far) being the final writeup of my PhD which brings all of these ideas together.

Paddy likes this, and suggested the idea of Pattern Language (used to desrcribe patterns in software engineering) which had recently been applied to Ubicomp environments to describe patterns in situations, Paddy thought that this might be particularly relevent to this, and that he would like to see some language of description emerge from our analysis. This sounds like a great idea. 🙂

Finally, Paddy spoke anbo
