Floor sensors

In tensive morning doing exams and planning next experiment. Y asked what do retailers and advertisers know about location of signs must find out.
Afternoon getting floor sensors working with new mac addresses and this time theyworked fine!
I am rebuilding floor grid looks exciting but need good two weeksbefore data.

DOWN

I'm feeling a bit slumped - why ?

Well I don't feel I did as good a job with the table as I would have liked. These few weeks I've had a constant stream of interruptions, some welcome like the cyber carpet and footfall but others like M255.

Being down stairs I've lost touch with everyone. Simon is hiding working all day in his 'music lab' s and having scored a number of interns for the summer who can blame him (o no chat there).I'm overwhelmed with the amount of junk email. I.e unfocused emails sent to almost everyone which are in generally irrelevant. It doesn't give me a sense of what's going on.

I'm not on every email from the M255 co-ordinators or at least this is how this feels. So I'm constantly being caught by last minuet - by the way you have 2 days to deliver this exam or that TMA or that meeting. So I think I'm getting upset by the general response to the questions which is generally that the grammar isn't up to much. OK its hard when you have a reading age of an 8 year old to re-read what was written not what is in your head and harder still when your under pressure to meet six deadlines at one and have no time to catch up when your at home or over the weekend. The whole dyslexic thing doesn't take kindly to criticism no matter how artfully framed or constructive in approach.

So I'm quite low and bitter about the whole thing.

Live from DANA center

Absence of blogging for a bit while I was in a tizz getting the big table working. After much work managed to get everything sorted. I'm currently sitting in the DANA center now. Falling behind on teaching work. Mean while the table was working but now isn't.

I'm now sitting in the cafe waiting for the event to get going. The table is off line I'm now stuck under a bit of direct sun light which completely overwhelms the tables vision system.

Talk from Tavs Jorgensen: Autonomatic

We are Autonomatic. We do research that explores the use of digital manufacturing technologies in the creative process of designing and making three dimensional objects

They have a digital loom (yum).

Accuracy of inputs is a real problem

Science museam here we come

I've been silent and stressed over getting the table ready for the science museam. Some bits to do but y. gave the ok to go with the software and the table style.
Richie is nearly wiped out but nearly finished with the attrium experiment.it's going to be huge I'm very excited by it.

Table Progress 2

This afternoon was mostly getting the sock to look smooth stretchy with out wrinkles enough.I've figured out that starting from the bottom and working up the excess can over the top and then be hidden under the felt. The big advantage of this is that I don't have to paint the edges of the table ( Tuur I still could do but would have to staple/velcro  the nylon to the bottom of the table.

From Tabletop

 This is the table in blue screen mode,in a dark space it would look quite elegant and inviting.  If we have time I might get Dave to smooth out the bits jutting down.  I also need to pull the power cable down ( does look a bit like a vein at the moment). 

Friday I'll need to get Mary to help sow on all the velco to keep stuff in place.

two weeks to go on the DANA gig..

I'm worried about the light ( will it be  to much  for the projectors). We now have felt new mirror and nylon. Dave has mirror and will move the the screen up. Found OUT people willing to try cutting Felt if we can get the outside in the box.

Need to sort out the software too. 

Time is running out. 

arduino ethernet

 and the senararium project is also having problems.

I can see these things in the lab but not outside 

 I've tried this and I can see it from the south wing

I couldn't find any on line code to check the ethershield working on Arduino so here is mine. You need telnet.

Interesting observation of the morning

Just noticed some people talking about signage in the building. 

Looks like the positioning of the signage is highly intuitive. Which is not to run it down, a visitor to the building is going to be better at evaluating when they need help rather than an occupant. There can be many non discursive elements to signage. 

From observing the conversation focus on visitors vs locals. 

Concerns with "messy" (visually cluttered). 

No strong notions of navigation. 

I never noticed that the sign to the pervasive area said 'post room'. 

Existental insideness

thounght for two experiments.
1.investigating by interview peoples desktops. Both phisical and virtual
when users have been using software for long periods they don't think consusly but use there body to remember.
2. Displays using expressions faces to visualize data like energy consumption up or down ( so a more emotional engagement). Also I suspect that text, images, signs and people are different categories when it comes to how people read signs. 

3. Why not put the attrium study up as an MSC project to gain more data. We have the write up why not get more data. 

C = 1.0 - (R/255)
M = 1.0 - (G/255)
Y = 1.0 - (B/255)
K = MIN(C,M,Y)
C = (C-K)/(1-K).
M = (M-K)/(1-K).
Y = (Y-K)/(1-K).

Unfortunately if you mix BLUE ( CMYK = 1,1,0,0) with YELLOW ( CMYK = 0,0,1,0) you get grey (0.5,0.5,0.5,0) not green ( 1,0, 1 , 0) 

I think the solution is to go to HSL space but be aware of the possibility that you can go either way round the colour wheel.
