Digital Pens, Again

About a year ago I posted a note about Digital Pens (Anoto, io2, and Fly). An old friend Terry Jones came across the entry and says this about his experience:

The paper is about $8 cdn delivered to your door so its expensive but compared to the cost of a tablet you can buy a LOT of paper.

The really cool thing I like about it is that each page is unique. So in my notebook when I update a page here and a page there and go back to this page and then crerate a new page etc… when I park the pen each of the documents I updated on paper gets updated online. There is also a timeline function in the viewer that lets me see when the various pieces of “ink” appeared on the pen page! I like to be able to write someone a note while I am working on their computer and then when I get back to the office I have a copy too (in the pen) even though I have left them the paper copy. I like the fact that on the subway I don’t feel like a total geek and a target writing on a tablet. I am just writing in a notebook with a pen that is only a little fatter than some modern pens. I like the fact that a notebook boots instantly so to jot down a quick reminder is NOT a 5 minute process of booting a tablet PC, making a note and shutting down.

I bought mine cheap on eBay ($51) and since then bought 3 more at around $60 on eBay and so far every person that has tested them out isn’t giving them back. They come back after a couple of office with their wallet instead of the pen… its been quite funny!

Terry, besides being organizing barefoot waterskiing competitions, is one of the most intuitive experts I have ever worked with. What he describes is ubiquitous computing the way it should be – not about what toys you show off or how you should change for technology, but developing technologies that fit our workstyles.

Digital Badges

I’ve been fascinated by the idea of wearable digital badges that could be programmed with messages. There are some affordable packages like the MessageTag or Mtag. The question (before I buy one) is … just what would I program it to display?

A related, but more sophisticated, product is nTAG which is essentially a small screen others can read off your chest. It has RFID and infrared so nTAGs can communicate with each other (“Hi, I like vanilla ice cream too!”) or with a central server. The nTAG web site is coy about privacy and costs. I think they rent you the service and don’t sell the technology, which is a pity, as it would be interesting to imagine some playful uses. For a story about nTAG, see Breaking the Ice 2.0.

QR Codes

James, a graduate of our Multimedia program who is working in Japan came by for a visit and showed me his cell phone and the cool things it can do. Besides controlling things like a Karioke player with the IR port and being an MP3 player, it can scan QR Codes which are two-dimensional barcodes. The barcodes are showing up all over – in magazines to provide a coupon or a URL, on business cards so that you can scan in a person’s contact information, and on screens. The scanning software lets you scan multiple 2D barcodes and then can merge the data into one file so you can suck up little programs for your phone. Above all it seems quite robust – both the QR Code system and, for that matter, the regular OCR with the camera that lets you scan English text.
If you want to try it, this QR Code Generator lets you generate the barcodes. The code above is my contact information encoded for the Vodafone scanner. For more on QR Code see QR Code features or qrcode.com. According to their site, there is no licensing fee to use QR Codes, which may explain why it is taking off.
