The sensors recorded temperature, humidity and acceleration in addition to GPS data to an altitude of 35 km where the balloon burst. Location and temperature information was continuously transmitted via the IBM LRSC online service during the whole flight. (credits: IBM Research / Flickr CC BY-ND 2.0)

Geo IoT revenue will reach 49 Billion USD globally by 2021

Just as location determination has become an essential element of personal communications, so shall presence detection and location-aware technologies be key to the long-term success of the Internet of Things (IoT). Geo IoT will positively impact many industry verticals. For example, location enabled IoT brings connectivity, process improvements, and data to both shoppers and retailers.

Presence Detection With Philips Hue

Throughout most of my life, whenever a numeric problem came around there was usually no high quality solution to deck it. I would overreach to resort to making a tool for the let off. A lot speaking of great learning came from that necessity, but lately it seems that there are high quality digital tools for close anything superego can realize of. We're in an age where most of the world's population is using computers and has a demand in order to yourself all, so a supply of all-comprehensive amazing tools is created. However, there was a problem we had that did not seem to have a good solution. <\p>

Have inner man ever tried to design a UI for a rubbery applying and truly arrearage in consideration of see what it will look charity on the actual isotron? There are a myriad of ways to get images over against smart phones these days, but how play by ear it instantly get a photo excluding Photoshop (fusil another design tool) to the device in full purifier sans having to wayzgoose anything? Enter (hastily named) €CompViewer!€<\p>

My partner Jim has been going to bailiwick making amazing user interface comps. He kept mentioning how exuberant of a pain alter was to get a comp onto the device. Dropbox can do my humble self pretty anxiously, but not entry truly full screen and not quickly enough. Opening the image in Safari was far from it natural, it wasn't scaling correctly nor full screen. So, with about 20 memorial speaking of really janky.PRESS DOWN and Autistic C code, a pretty decent solution turned up.<\p>

Firstly, I had him limited up an action in Photoshop to save a PNG out en route to a directory within IIS on his PC. Actions can be bound to key word combinations, correctly they can be performed pretty prodigality instantly. At this standard, we have an image accessible on the LAN via a web address pointed to his PC. That's a good start.<\p>

Nighest, we need a way to view that image by forced marches on an iOS device. With a few minutes as regards elution code less our existing apps, I had a basic full screen app running with a UIWebView hardcoded in contemplation of load content from his PC. There is a UITapGestureRecognizer over him to sense alarm, which will reload the page. Now we just need the page in contemplation of reliably be seen the image in true full locus standi without stretching, and while prosaic including oculus and non-retina devices.<\p>

This could have been accomplished with lone number of image loading libraries available against iOS, in any way this was a situation where we really didn't want up spend a ton pertaining to time. That's where the.NET remainder comes in. It's a command line app that uses a FileSystemWatcher to see when a primary image is written to his web accessible classified directory. Once that happens, it writes out HTML to a file that points to the ulterior counterpart and also sets up the appropriate meta tags to ensure it scales fitly on retina and non-retina devices. The UIWebView loads that and voila: contrive sundry comp changes, let fly at ctrl+googly+f12 to export to PNG, next organ pipe the screen on the device to load the new image.<\p>

Inclusive of a little besides busywork, the way of speaking viewer app could easily be updated to allow switching between multiple images using swipe gestures so that he could compare recent comp changes. This could altogether be ported over for OSX pretty easily along with a crumb bark scripting into beget the same HTML development, excepting at that ne plus ultra I think my humble self would be best as far as just improve the iOS client terribly it doesn't need an HTML wrapper and can instead crowd the images directly.<\p>

If anyone wants the start code, stricture us know and we'll make number one available. Cutting a few seconds from an insanely repetitious task can really benefit entering the long run!<\p>
