Supervisor Meeting 02 Oct 2008
Met with Paddy and discussed what we need to be on with – we both seem to have been thinking about different things – I seem to have gone down a route of something to do with mobile phones – but it needs to be linked to what we are getting at. I said that I don’t really know what wearable computing really means – as I haven’t seen it in the flesh!
Really need to get into the idea of what infrastructure is needed to make wearable systems work – think of it more as network of wearable sensors.
What issues are there when we are thinking about transferring data amongst nodes – what if instead of being centrally managed – what if they could freely communicate with each other.
Discussed the idea of city wide environmental sensing – a mixture of fixed and mobile nodes which are tagging and recording data – offloading to nodes with big pipes – how does this work – and how do we implement it?
Also need to think about issues such as transient and persistant data – what is kept and what is shared and removed – what is private what is encrypted what is not?
Example application is
citywide environmental monitoring – fixed nodes talk each other and share data,
they also talk to mobile nodes to get data –application to monitor an area.
Nodes about the body can
communicate to other nodes on other bodies, handing off data – gossiping –
every piece of data has timestamp – and is tagged so that that it can be
synchronised at a later date.
Also – talked about developing some things that we say is good for
wearable computing – i.e. p2p vs managed nodes then compare previous wearable implementations
to our idea of whats best and see if they succeeded.
Hundreds of shimmers
downstairs in clarity to have a play with.
Speak to Julie doyle
about user study – work out what we are trying to get out and keep it in the back of my head.
Paddy suggested this was a turning point – are we
interested in hard computer science part? Or more the HCI part?
Overall we really get down to the
basics –
about P2P vs Central Node?
What is persistant
what is transient?
Matt Walsh – they have
the OS with low level access to data – what do we need to do to get something up and running?
