Medoids

Today we played around with this concept of cluster analysis. We categorised the open questions of the Teamframes questionnaire and now we are trying to see if the respondents answers are in some way grouped. The picture below shows the daily result. the goal now is to determine which factor mostly contributed to define the centres of the ellipses, namely the “medoids”. this will help us to make distinction in the population of the students to try to find good conclusions out of the analysis of this questionnaire.

The framework can be situated cognition: the context is a resource for the reasoning or problem solving or cognitive activity. In the context of geologist they explained that when they have to measure something at a specific location they memorise the area (if there is a river, a road, …) plus they take a picture of this place with a camera, plus they record the GPS location, they write it on their notebook or on their map. All this tasks to help them to remember.

Mogi item hunt

Mogi is a community game where a web player can help a mobile player to get closer to a virtual object. An instant communication can help the two kinds of user to get in touch.
The system offer a 3D view on the internet which translates into a 2D view on the mobile phone. From the technological point of view the system uses an hybrid positioning system GPS plus Radio cell.

The pictures hereafter are takes from the game internet site.
