I am having my first go at getting my son’s iPad setup with LAMP Words For Life  (LWFL) setup. It’s exciting thinking about how this may open up better communication between all of us. I will be posting little bits of info as I come across them and hopefully it will help others who may be digging for the same info I am. I will be updating each post topic as I work thru things.

iPad Icon Size

One of the key factors I was concerned about before getting started was that I knew that this app was displaying a lot of images and that the images that came as part of the default vocabulary files are from an era where HD displays were not even dreamt of yet. The icons are low res, pixelated and often don’t look much like their real world counterparts. I knew I needed to make things as familiar as possible for my son as he is very much a creature of habit and accepts things that are familiar much easier than something he may have not had contact with yet. When picking out our device I knew that loading up detailed images of real world objects might be a issue, not so much because of hardware limitations since I figured the iPad could pump out the horsepower needed, but maybe the software might have some bottlenecks either for being fairly new or bringing legacy issues forward. We picked the iPad Air since it was the fastest unit at the time hoping it’s faster processor would help keep things snappy when switching between pages. LWFL imports images from the iPad’s camera roll. during the import process, it presents your with a crop tool but I didn’t know if the software was simply cropping the image on the fly, or was it actually creating a nice small icon adjusting the resolution and dimensions or what. I started a test vocabulary file to play with, and began replacing images. I used large +900px images and things seems to be running pretty good. I then removed some of the images from the Camera Roll, and the images stayed in the software so I knew it was at least storing the images within the program, which was good so didn’t have to worry about my son deleting images and breaking things. But I had only replace a few test images. Would the speed keep up as I loaded more and more images? I didn’t want to get weeks into setting up Daniel’s core custom vocabulary file only to be hit with a performance issue and have to start all over.  I posted a question over on PRC’s Facebook page [because any company worth it’s salt will respond to someone questioning the quality of their product in an open forum in front of millions of potential customers to keep up their company’s image up 😉 ] and with  PRC’s speedy response, I found out that the internal icon size is 5/8″ x 3/4″ (0.625″ x 0.75″) or a  1:1.2 ratio. “Cool!” I thought, “They are creating their own images and resizing them down so I should be good to go.” So I started to create my son’s custom vocab file. I edited my images on my PC & upload them to my website. Then on the iPad I would refresh the page in Safari, save the image to the Camera Roll and then import the image in LWFL. Using the 1:1.2 ratio though I was getting outlines showing up on the edges of the image. It seems a square image usually works better. I got about 50 images in when things . . started . . . to . . . . slow . . . . . . .down. I though “Ahhh crapo. They are cropping, but not resizing.” I exported a standard 84 full vocab file and my custom vocab file to iTunes and compared their sizes. About 20 MB’s difference. All of my custom jpeg images only added up to about 4MB total. So I am left to deduce that either the image processing on the iPad is creating some larger files or there is some sort of overhead or meta data going on inside.

(I have posted a question on Facebook about this and will update this when I have a answer.)

So after hitting this snag, I have gone thru and tested multiple formats, sizes and resolutions.  I am getting best results using 450X450 px and 600 PPI which results in an image about 30-40kb per image. I am going to go forward now using these sizes, adjust my existing images and go on from here. I know the iPad Air has a screen resolution of 264 PPI, but I compared 264, 528 and 600 (600 just to try a nice round number) and the 600 looked the sharpest. I tried 792 & 800 but didn’t any difference in clarity, so I stuck with 600 PPI.

Getting transparent icons into the iPad app seems like it is going to require building the vocab file/icons using the PASS software and purchasing a license to the iShare account service to sync with. The PASS software is pretty rough (old & clunky like the Vantage Lite units), I am not quite ready to setup a iShare account. Will probably end up needing to sync my son’s personal and school device up using iShare with the teachers, but not ready to do that just yet. These colors match the standard app colors but unfortunately it seems the colors used when editing icons within the app have a gradient so they don’t quite blend in naturally, but these colors will get you pretty darn close. I am going to just color my standard icons and forget about trying to do transparency as I can probably get these color added as fast as trying to convert the vocab PVF files in and out of the PASS software.
