Going shopping with QR codes – A use case

July 8th, 2011 by Daniele

You cannot deny that, little by little, QR codes are pervading our everyday experience. Museums and commercial boards are more and more using them to hide a URL pointing to some online resource.

According to the MHG marketing agency, the awareness and the use of QR codes in the world are  growing very fast:

The survey results found that 65% of smartphone users had previously seen a QR code. [...] Of those respondents who had previously seen a QR code, nearly 50% said they had used one.

Even Mashable has recently published a nice infographic by JumpScan in which states that in the second semester of 2010 there’s been a 1200%  increase of QR codes scanning:

 

Anyhow, until yesterday, I had always been thinking that what was missing was a large scale experience, involving the urban environment. I was wrong. The grocery chain  Tesco has been doing that in South Korea with the goal of becoming the number 1 in sales in a Country where the second most hard working people in the world live .

The idea is to create virtual stores in places were people are normally spending their everyday life, like subways, placing there displays designed to look like actual stores. The products are showed and smartphones are used to virtually shop. How?  Just scanning a QR code to add the items to a virtual cart. After the payment, made with the smartphone itself, the purchase is automatically delivered to the buyer’s door, saving a lot of his precious time.

The results are stunning. People are actually using it and Tesco has become the first online grocery store in South Korea, increasing its online sales by 130%.

Personally, I have to admit that I love to spend some time at the grocery shop and I have never bought any food online. But  that is especially because I usually don’t know what I want to buy when I enter one. The idea of placing the product displays brings in the possibility to choose among the available products, providing a more natural (to be tried) experience.

SixthSense: a step forward in wearable computing and gestural interfaces

July 3rd, 2011 by Daniele

We grew up interacting with the physical objects around us. There is an enormous number of them that we use every day. Unlike most of our computing devices, these objects are much more fun to use.

This is the beginning of a ten minutes talk by Pranav Mistry, a PhD student in the Fluid Interfaces Group at the MIT Media Lab that will introduce to you his invention, SixthSense. I have to admit it: when I first watched this video I didn’t know about this technology and my only comment at the end of it was “this guy is a genius“. He has been able to create something exceptional starting with a simple tool we use everyday, a mouse. Then he added a second mouse. And, this way, with a series of small simple steps he has obtained a revolutionary device.

SixthSense, according with Wikipedia,

comprises a pocket projector, a mirror and a camera contained in a pendant like, wearable device. Both the projector and the camera are connected to a mobile computing device in the user’s pocket. The projector projects visual information enabling surfaces, walls and physical objects around us to be used as interfaces; while the camera recognizes and tracks user’s hand gestures and physical objects using computer-vision based techniques. The software program processes the video stream data captured by the camera and tracks the locations of the colored markers (visual tracking fiducials) at the tips of the user’s fingers. The movements and arrangements of these fiducials are interpreted into gestures that act as interaction instructions for the projected application interfaces. SixthSense supports multi-touch and multi-user interaction.

In few lines there is a new world explained.

My advice is to really watch this video to get to know the amazing possibilities brought by this wearable computing device: if you have seen Minority Report thinking that what you where seeing was just sci-fiction, you will change your mind soon. I especially love  the  conclusion of the talk, that sounds a bit as a mission:

So, as a last thought, I think that integrating information to everyday objects will not only help us to get rid of the digital divide, the gap between these two worlds, but will also help us, in some way, to stay human, to be more connected to our physical world. And it will help us, actually, not be machines sitting in front of other machines.

These is an excerpt from the talk just to give you an idea, if you are too lazy to watch the video. I am sure you will want to watch it after reading it:

You can carry your digital world with you wherever you go. You can start using any surface, any wall around you, as an interface. The camera is actually tracking all your gestures. Whatever you’re doing with your hands, it’s understanding that gesture.

Rather than getting your camera out of your pocket, you can just do the gesture of taking a photo and it takes a photo for you.

So, we are looking for an era where computing will actually merge with the physical world. And, of course, if you don’t have any surface, you can start using your palm for simple operations.

Taking a picture with SixthSense

Here, I’m dialing a phone number just using my hand.

The camera is actually not only understanding your hand movements, but, interestingly, is also able to understand what objects you are holding in your hand. [...] For example, in this case, the book cover is matched with so many thousands, or maybe millions of books online, and checking out which book it is. Once it has that information, it finds out more reviews about that, or maybe New York Times has a sound overview on that, so you can actually hear, on a physical book, a review as sound

SixthSense

And you can of course play games.  Here, the camera is actually understanding how you’re holding the paper and playing a car-racing game.

Augmented reality, movie scenes and geolocalization…

July 2nd, 2011 by Daniele

Augmented reality and movies

Has it ever happened to you to to be in a place where a famous movie has been shot?

To me, yes. Last time it was just a couple of weeks ago. Ok, I need to admit it: I am not that proud of the movie, even if the location was great. I was in the city in which some scenes of the New Moon movie take place (yes… the one of the Twilight saga; yes… the one with Robert Pattinson and Kristen Stewart – now you can stop to read this post, if you landed here following some dirty Google search). As many of the fans of that saga know already, part of that movie has been shot in Montepulciano, Italy (causing some contention, since in the book those scenes where set in Volterra, Italy). Well… I didn’t know all of this. I haven’t even seen the movie, I swear. But… it was so full of posters that it was impossible not getting informed.

Anyhow, if you happened to be in a situation similar to mine (maybe, hopefully, even better), i bet that you have been imagining the actors and the scenes of the movie while wandering around the city. I have been doing it with Angels&Demons in Rome. I even imagined to be Tom Hanks!

A new conceptual smartphone application aims to something better just imagine it: (apparently) using the GPS location data and the integrated compass, Augmented Reality Cinema will allow movie fans to watch the scenes of a movie that were shot at their current location directly on the device screen. And, wanting to be an augmented reality experience, images from the camera will be integrated, so that you could be part of the movie too,

Unfortunately, there is not much of explanation on the official website, but a video will demonstrate you how the application could be used in London, where the number of shot movies is certainly not small.

The conceptual prototype looks interesting, I would be more than curious to see it in action. I don’t know any application already able to add some real-time image into a pre-recorded video, so, even from a wider point of view, it seems to me a great research topic.

Haptic belts to guide soldiers (and give them orders without speaking)

June 30th, 2011 by Daniele

Soldiers

We live in a mad world. A world where, for centuries, what has been leading the progress has been mainly a unique factor. War. For this reason, it doesn’t surprise me to discover that some of the most advanced research in the pervasive computing field is related to it. The key word of today is haptic:

haptic /ˈhaptɪk/

▶adjective technical relating to the sense of touch.

This is the definition by the Concise Oxford English Dictionary. To say it in an easy way, in the Computer Human Interaction (CHI) field it means to use the tactile  sense to drive the communication between the machine and a person.

Some examples you have probably experienced in the past can be the vibration of the seat in 3D movies at some amusement park or the guns of the last generation games at the penny arcade that reacts when they shoot. Or the entire Laser Tag game.

After entertainment, the new frontier of the research on haptic devices seems to be the Army. As told by Elmar Schmeisser from the Army Research Office in North Carolina to the magazine NewScientist

navigation can be extremely difficult for soldiers, especially at nigh. GPS devices are not ideal as they require soldiers to take their eyes off their surroundings and their hand off their weapon. The illuminated displays can give away their position at night, too.

The solution he found working with different research groups is a belt worn around the torso by a soldier having  eight tactile sensors embedded, one toward each of the cardinal directions, vibrating and indicating to the direction to follow to its owner. The device can be then connected to a GPS system or it can be  controlled by some external device, allowing to give orders without any need of speaking. As said by Linda Elliott, a psychologist who has been testing the systems on soldiers,

the hope is to allow a platoon leader to be able to communicate with their squad while out in the field through standard military hand gestures sent wirelessly to their belts.

What a scenario! This seems to be one of the first real life uses of some wearable computing technology.

My best hope is that, as often happens, something originally thought to be used by the Army will soon be adapted to our everyday’s life. After a some fast thought I can imagine a similar system used for example to help blind people moving inside the city. This is just an alternative use case and it’s just a beginning.
