Sporbarhet - Tracking food

foredrag av Ola Hedstein, Nortura (innovasjonsavdelingen)

Nortura:
Nortura eier Gilde og Prior
De produserer mellom 100 og 150 nye produkter hvert år (Eier bl.a. Alfathi (Halal kjøtt))

Hva vet du om maten du kjøper?

Kundene har forskjellige motiver for hvorfor de vil vite mer om maten, men i følge Nortura er en fellesnevner for dem alle er at de vil vite mer enn prisen.

"Trace and Track"

E.colisaken i 2006 var en enorm sak i Norge og en stor sak i Europa. 18 ble smittet og ett barn døde. Økonomisk gikk nesten 100 millioner kroner tapt. Det var mye data tilgjengelig som det kunne spores i, men resultatene uteble. Siden kilden til smitten var ukjent hjalp det ikke å spore i eksiterende data. Utvidet sammarbeid var akkutt nødvendig og sporbarhet ble virkelig satt på dagsorden.

Hvorfor trenger man å spore maten?
Katastrofe og frykt er særlig drivende midt i en krise (som i 2006). Men blir skjeldent tatt hensyn til før katastrofen er et faktum. Dessuten dimensjonerer man ofte ikke systeme…

Task 02 - Making RFID Work

"Cuba Libre"

We have started our RFID journey with the cube as our first RFID enabled interface.

On each of the six sides it has one RFID tag. Those tags enables us to identify witch side of the cube that is the closest to the reader and therefor its orientation. This will later be exploited as a navigational tool for a "cubistic" game.



From our testing we have confirmed that the technical part works fairly well. The cube can be held at a short distance (3-6 cm) away from the reader and still pick up the right tag. Also spinning it quite fast, with 1-2 sides per second, works well.

Our goal for the week is to test how it feels to move a virtual avatar with our physical cube. So the challenge, and our focus, lies with the feel of connection between the physical move and the virtual onscreen move and feedback. That will be researched with various tangible iterations of the cube (weight, size, softness and material) and development of the game play, graphics and possibly…

Sniff - Playful RFID

Playful toy for blind children.

Rfid offers the oppertunity to interact on a distance. The research revealed that it should be Socially Engaging and Physically Activating. And it should not be too smart, so that it replaces other sences, wich leaves no imagination for the child.

Making prototypes early in the project is the most important thing for a successful project. Wich is a commom lesson everyone that has made similar projects have learned. So Tangible and Physical interfaces need physical prototypes very early in the project.


Sniff is meant to be a stimulational tool (training the sensens) and not a aid for solving tasks. The magic is in the unexpected so the low tech and soft object is a fitting contrast to the high tech interior. That it is unconnected adds to the magic. It looks to be intelligent.

Sniff has to main functions: Moods/Emotions and Memory game/Melody Game. It has vibration and sound feedback. There is two types of rfid tags; marbles and stickers (w…

A simple RFID interface (Task 02)

What kind of RFID interface can we make?

We brainstormed in the group (Gudmund og Ingrid) resulting in this list of possible interfaces:

Music
- change of tunes and modulating them.

Childs play
-Memorymix
-React to images on the screen and put the required item on the reader as fast as possible.
-IQ test
-Reaction test
-Couple images or movies with the right physical item.

Coffe cup
-Payment and filling in one operation based on the identity of the cup

Cat door
- Opens on proximity
- Releases food

Instrument
- Sampler, tags represent notes, tones and beats. Add them to the mix to make a tune.

Jewlery
- Access control

What do we use identification for?
-Safety
-Identifying
-Confirmation

Ticket wending
-Buy tickets from posters in the street.

Art show
-Tag images that can be read by viewers

Paper w RFID
-Transfer information from paper to screen

Navigation
-RFID i bakken as tracking points for moving vehicles

Colour
- Mixing colours by adding different colours

Game
-Cube with RFID tags on the sides that control a virtu…

Introduction to Tangible Interaction

We were handed a compendium on monday, covering a broad range of tangible interaction issues, compiled by the tutors. This is meant to be a primer for our research into this field. Below are the five research areas presented in the compendium. I try to write down terms and issues that i want to discuss later on.

History and background:
From Nicola Tesla to Mark Weiser there is a shared optimism of what technology, used in the right way, can bring the future. Concerns about how the footprint of new development can be reduced is discussed by John Tackara in the book "In the Bubble". Realizing the future requiers a holistic approach to design.

Ubiquitous computing:
The vision is to move computation to a new level, into the culture and social aspects of our lives (away from technology). The role of the designer is to take computers out of their cradle and release them into the real world.

It is argued that current research is stuck in the past visions of the future, especially Weise…

Tangible wisdom

This semester at AHO will be an endeavour into Tangible Interactions. We will be looking into several fields of research in Tangible interfaces, Ubiquitous Computing, Radio Frequency IDentification (RFID) and the associated theories. The course is driven by the "Touch" research project at AHO

Our tutors are Timo Arnall, Einar Sneve Martinussen and Mosse Sjaastad.

I'm looking forward to a semester where i will gain wisdom on new subjects.

I have just uploaded a bunch of pictures to flickr. It is a big time killer! I must go "pro" in the near future, i fear.
