Some time ago I was truly thinking to something like that: a device that could record a part of my life. There are a couple of projects that are going in that direction (see the wearable life monitor). Nicolas pointed to the Sensecam project at Microsoft.

So it seems that there is an interest in recording a part of our life not just with the pictures but with other sorts of logs:

1- the trace of our path; the positions were we go; the places that we visited (Step logger);

2- the emotions that we feel at some point in time (Greenwich emotion map);

3- the pollution that we are exposed to during the day (feral robots);

Collecting these traces is so intriguing that we also want our pets to do the same (AIBO-life). But what’s the value of recording this information? Comparing? Remembering? Sharing? Maybe a combination of these.

Technology is reaching the critical point where all these simple recording will be facilitated by thousands of cheap sensors that we will have all around our premises.

Nike and Apple went commercial with something like that and I decided to give it a try. I find extremely interesting to look at the recordings of my runs because it helps me to compare my workouts and to fix specific challenges. There is also a value in remembering after a while what it was that particular run. Pretty much like this blog helps me to remember what I was thinking at that time.

I found this nice collection of Information Retrieval Tutorials for IR students and engine marketers. Some include examples, fast tracks, reader’s feedback, reviews or exercises. Nice work.

Recently Google filled a patent on serving dynamical offers using the position of the user. The main principle is that of offering driving or walking direction to the user, detailing the resources at the end point of the direction and along the way. Seo by the Sea explains in details how this can work.

This week end we visited Canon Beach, in Oregon. It was truly one of the best w.e. ever here in America. The landscape was astonishing. We spent hours on the beach, playing with the sand, walking, bird-watching. It was a great emotion: our first time facing the Pacific ocean (my foot in the water). The water was freezing, I couldn’t believe that people were swimming in that cold.

On Saturday, we ate at the Lumberyard, a nice and cosy restaurant. We had crab and shrimps pankakes! On Sunday I managed to buy a kite that I am planning to fly next Saturday. We found this nice place called Pinky’s Kite Factory: they had tons of different kites and it was very hard to choose.

Interaction Design Lab, a startup created from the Interaction Design Institute at Ivrea, is conducting an interesting research on participatory design of art installation. Their approach is “to go on the field” and ask people how the art installation should look like:

In the beginning of July 2006 we have installed our work base in Cagliari. From this privileged observatory we will develop our project for the Mediterranean Museum of Nuragic and Contemporary Art architectural competition.

Now we start off by launching a first base camp: for two whole months, July and August, a hangar in the port of Cagliari is the place we start from to discover and learn about Sardinia. It is a place for work, fun, exchange and research. We want to take advantage of this fantastic site to meet people and listen to their experiences, ideas and suggestions. We look forward to invite you inside our landscape to show you the conceptual frame of our project. This Wednesday 2 July at 19:00, we will present our explorations of Cagliari going from our base camp to the Lazzaretto peninsula – to the airport – along the Salina –then through Cagliari downtown and onwards to Pirri.

We will take you to a media landscape and we will explore together your city.

 

See you at Marina di Sant’Elmo, Calata dei Mercenari, Loc. Su Siccu, Darsena del Sale, Cagliari, Italy

I had the great opportunity to discuss with S. Dumais of my thesis’ project. One of the main questions I had was how to evaluate the goodness of a retrieval algorithm for geographical messaging. Dr. Dumais pointed out that any implicit measure of effectiveness is extremely dependant from presentation. How results are arranged, which font was used, which color and which position in the rank list is going to affect the way people will use the system.

Additionally, users have different speed while browsing. They have different cognitive styles that bring them to formulate queries in a different manner.

In my situation is very difficult to propose a way to establish similarities and to measure effectiveness because I do not have a clear model of what tasks the users are trying to accomplish. The system support open ended conversations which reflects in the lack of specific tasks. Along the same argument, it is very difficult for me to define which factors are important in the query / selection. My top list currently includes: semantic matching, geographic proximity, social rating, and contextual appropriateness (a mix of spatial and temporal factor in relation with personal objectives).

On the other extreme of the spectrum, we have the standard IR evaluation techniques that suggest having the effectiveness measured a priori by judges. The challenge of this approach resides in the fact that detaching the application from its natural constraint invalidates completely its ecological validity. Also to evaluate with this technique one needs to keep the query constant between two different algorithms.

A live system introduces noise in the evaluation process. Dr. Dumais pointed me to different studies trying to evaluate different presentation techniques (like Optimizing Search by Showing Results In Context).

Finally we brainstormed a bit on possible ways to tackle the problem and find a new approach to give the best matches. One of the ideas that emerged was that of the batch measurement of relevance (the user throws a query, the system returns a list of all the results and the user is asked to define the relevance). Another idea was that of leaving the community decides on the relevance of a certain result.

This is cool! When working on my master thesis I was always looking for this kind of games, which could help kids (and adults) to understand some more of the life of plants.

From the creators of Diner Dash comes Plantasia, a game of gardening delight. Enter your luscious gardens, where magical flowers and a fairy-in-training are waiting to show you the way. Plant seeds, harvest flowers, restore fountains, and watch as your gardens bloom. But beware! Weeds, rocks, insects and the clock are all waiting to make your game a fun-filled challenge.” Players restore one garden after the next, choosing flowers and gardening spells as they discover how a fairy wish unfolds. The game features 50 levels, more than 35 types of plants with varying blooms, five gardens, multiple emotional states for each plant, and two modes that consist of “Holly’s Story” or “Garden Challenge.

The text below is an excerpt from the commencement address at the American University that the President John F. Kennedy gave on June 10th 1963 in Washington DC. I found it extremely inspiring and appropriate in regards to the recent developments of the international politic situation.

What kind of peace do I mean? What kind of peace do we seek? Not a Pax Americana enforced on the world by American weapons of war. Not the peace of the grave or the security of the slave. I am talking about genuine peace, the kind of peace that makes life on earth worth living, the kind that enables men and nations to grow and to hope and to build a better life for their children–not merely peace for Americans but peace for all men and women–not merely peace in our time but peace for all time.
…
So, let us not be blind to our differences–but let us also direct attention to our common interests and to the means by which those differences can be resolved. And if we cannot end now our differences, at least we can help make the world safe for diversity. For, in the final analysis, our most basic common link is that we all inhabit this small planet. We all breathe the same air. We all cherish our children’s future. And we are all mortals.

This last week end we visited Portland. It is a nice city: lots of things to see and not chaotic at all. We did some shopping although most of the shops are closed on Sunday. The cool thing is that they do not apply the VAT for the goods. We rumbled around the city for the most part of Saturday, ending up on the park facing the Williamette river of Downtown. We had dinner at the “three degree restaurant“, on the river side. Funnily, the food was high quality and the prices were ok, but in Oregon is “considered” fair to leave 18% of tip for the service.

On Sunday we visited the Japanese garden, in the Washington park. After I could had a look at the Powell city of books: one of the biggest bookshops in the US.
