i haven't updated in quite a while, and to a certain extent, it's a reflection of my current mind state.
as i mentioned, we had the fancy internet/phone outage which pretty well destroyed any momentum i had going. thankfully, that wasn't the case for the whole team.
david did suggest that we take a break, and to that extent, it doesn't seem like the lack of productivity is a bad thing.
i think part of it is that my workload this quarter is so inconsistent with what i had going on fall and winter. i went from being enrolled in 20 credits, then 22 credits, to being enrolled in 13 credits, and though i'm still in lab just as much, i feel like not nearly enough is getting done.
but things are getting done.
we met on wednesday night to discuss our software framework and decided on c++ as our language, thanks in no small part to opencv (which is also c++).
we also discussed our data structures and object model. eddie is going to pass me an object that contains a camera reference and set of blob objects. i'll use the camera reference to look up calibration data to convert the blobs from local blobs (per camera) to global blobs for the whole table.
we also received shipment of the new, correctly sized aluminum channel that we're using as a bezel. last night we put it all together on the prototype with a full strip of ir leds on each long side. the effect this had on our touch detection is remarkable. the amount of pressure required to generate blobs is much less, and even matt's cold, bloodless hands generated blobs.
heh. i should clarify, in previous tests of our prototype, matt's fingers have consistently been very poor in generating blobs upon touch. they're the worst of our whole group, but it's a great asset to the project since it forces us to consider the spectrum of users who will be using the table. we've also discovered that our fingers work better as input devices when they're hotter or when they're wet, hence the joke about matt's hands being cold and bloodless.
we're at another point where we're waiting on shipments, again of the ir bandpass filters for the webcams. it's putting a slight delay on my, eddie, and zach's work, but we're diverting ourselves in the meantime to other tasks that need to get done.
we have all of the wood, and if all goes well, tonight we will complete the construction of the final table, sans glass, of course. i've been lending my hands to the woodworking so that i feel productive, but i still feel like i'm not doing much.
i still need to finalize this letter to porter college to get a nice DSLR camera for our lab (and for IEEE after this quarter) for documentation.. i'll be helping build the table tonight though.
next time i should remind myself to touch on our relations with projection screen suppliers and showcase shower door company.
time for woodworking.
