Datamatrix is coming!

Good news for those who want to use iMatrix as 2D code reader. I am testing Datamatrix recognition right now! In a few days you can get it via Installer. You will be able to read Datamatrix codes in Nokia style or Semacode as well.

Real magic of iMatrix on video

This one is really cool. Watch how easy to transfer contacts from one iPhone to another! In reality you can use it for other information as well...


iMatrix video demonstration!

This is the first home made video about iMatrix possibilities.

iPhoneworld.ca: first blog with iMatrix integration!

Today, one of the most popular blogs about iPhone, iPhoneWorld.ca, integrated iMatrix. Each post is marked by iMatrix code in title. Now iPhone users can open articles directly from mobile phone just shooting a code from monitor. iPhone users get pages adapted pages for best readability.

Corrected Handling of Contacts!

Today I fixed one of the most serious bug - incorrect handling of contacts during import/export operations... Thanks to all of us who reported it and spent some time on debug. That was a case when having three phones cannot guarantee compatibility with all others.... You can get updated version from my repositary as described on iMatrix site or please wait one or two days when it will be avaialbe in Installer.

Export for Bookmarks

New feature is ready:) Export function for Safaru bookmarks. Now you can share your links freely... I plan to add export for Safari's history today as well. New version on application in two days in Installer!

Wordpress integration

This weekend I have installed copy of Wordpress at home and found a way how to integrate iMatrix code to each post automatically. Process is simple. If you like to add this to yours - contact me. Soon, integration guide will be availalbe online...

One of popular blog agreed to test it today:)

iMatrix video (on german)


Well, thanks to ifun.de I have small video about my application on German language. I should have one on English.... Anyway, that movie ranked forth "Top Linked" movie this week on German segment of YouTube. Not  bad for such a specific product.

Hot news: Export function

Friends,
iMatrix has new exciting feature - export of contacts. Now you can create codes for contacts just from your iPhone. Than is not the only feature. Soon, you will be able to export bookmarks and notes as well. New, version 1.24, will be available from Monday, 2007-12-10. Try it!

First feedback

That Monday was very interesting!
Russian iPhone users helped to find one bug with unicode processing and pointed on a lack of help on registration process. I have fixed both.
Some users asked to create public forum or place where thay can share codes. I like that you need it. Practically, I have planned to do it later but now I have to change my mind.

Then, I have got comments from Semacode team. The main difference between our projects is that I try to establish e-ticketing or mobile commerce platform and I'm not so interested in simple code recognition. Therefore, I need small and reliable code that can be decoded by majority of phones, not iPhone only. For that task I cannot use textual information, encode URLS as text. I can rely on short and well compressed string of digits.
Also, I what to make each code dynamic but not seal it immediately after creation.

Birthday

Well... Today is the first day of operation! iPhone application works, web site created and offers required minimal functionality. Also, web site can be viewed as https:// or http://
Any comments are welcome!

iMatrix.app beta

Well... Now I am ready to announce first milestone - iMatrix application (beta) is ready! Nearly all planned functions are implemented:
- 2D code can be extracted (CRT/LCD monitors, paper or other media); FEC + BCH implemented; some correction of perspective or other geometrical effects....
- redirect to web links;
- creation of records in Contacts, Calendar or Notes;
- initiation of Phone call or E-Mail message;
- Synchronization of purchased codes with iMatrix server.

Now we can start testing and improving it. Big hole is a web site that is a must:( Working on it hardly at the moment.

Want to play with it?
1. Register on www.iMatrix.LT and create some codes.
2. Install iMatrix on your phone: add new source to Installer: www.iMatrix.LT/repo/repository.plist, refresh sources and go to 2D codes -> iMatrix.

What are these squares?!

Most of us knows what barcodes are and feel their importance in our lives:) Virtually any thing we have has or had label with barcode on it. This set of white and black lines automates job of cashiers, simplifies logistics and significantly reduces human factor:)

Humans need more and more... Barcodes came close to limits - they cannot keep as many data as we need. Next logical step was to use two dimensions in stead of one. It means useful utilization of area plus new features like error correction that allows correct reading of code even if it is damaged partly. Lines became squares. Of course, detection of 2D codes needs more powerful devices and sophisticated mathematical algorithms. Fortunately, modern electronics can supply required things.
There are plenty of different standards on 2D codes, some of them are QR Code and Datamatrix. Both offers reasonable informational density, comparable error correction possibilities; both require similar processing power. For me, the most important feature is an ability to capture and process 2D code by low resolution cameras built into modern mobile devices. I use QR Code.

To scan barcodes, either laser guns or linear image sensors are used. To detect 2D code we need real picture and use CCD or CMOS sensors similar to ones built into digital cameras.

In spite of possibilities of modern 2D codes to keep huge amount of data (even 16 KB), consumer phones offers relatively low optical resolution products. Take into account noise in dark environment, focusing problems and dirt on lenses... As a result we are limited in code size. General rule is - the bigger squares and higher contrast between black and white elements - more reliable reading we have.

My application is based on QR Code that can keeps 27 decimal digits and offers correction in case of corruption of 30% of the code.

It is enough for indexing services I plan to create.

First capture works!

I started this project about two weeks ago and passed some rubicons already: istallation of tool-chain required for development and activation of missed frameworks. Taking into account that it's my first experience with Apple's products, that's not too bad! Actually, my favorite products, including development studio, come from B. Gates hands:) Therefore, using command line tools became amazing surprize for me! Objective-C... another new universe... but, anyway, two weeks after I have application that captures images and process them somehow.... It reality it decodes QR Code successfully! It's time to implement major function...

Let's start...

Hello everybody!

That's my first experience in blogging and, hopefully, it'll be usefull;)

The main idea behind this blog is to log a history of porting my Matrix application to iPhone platform and establishing life feedback with potential users.
My dear friends, let me introduce idea step by step... 2D code processing applications for mobile terminals become my hobby more than one year ago and I need time to share some ideas with you.
iMatrix platform offers atractive and simple way of handling data input into limited (mobile) devices and in particular case - into Apple's iPhone. In general, phone must capture image of 2D code using built-in camera, process picture and extract code from it. That's minimally required functionality. All other features need that background.

Let's start....
