NordiCHI’08 notes

2008 October 25

NordiCHI 2008, Using Bridges, October 19-22 2008 in Lund, Sweden.

NordiCHI is the main Nordic forum for human-computer interaction research

Sunday October 15

Workshop 15 – Haptic interfaces, making use of gestures, force feedback and tactile devices
Previous workshop at CHI,,


Charlotte Magnusson

can we ask the user right away? even with haptic
previous works/prototypes can help a lot
needs: technology + easy prototypes

Steve Brewster

non-visual information
issues: vibrations is easier to do, but worst than proper force feedback
3 cell pin array
C2 tactor actuator
Tactaid VBW32
Shake sensor pack, new updated version coming soon

Jukka Raisamo ,TAUCHI, Tampere

tactor in balsa grip, signal coming through audio jack

Erika Tanhua, TAUCHI, Tampere

models: cardboard and plastics
tangible modles in early prototypes for teaching blind children before moving on to the Phantom



Tim Brooke, Nokia Design London

gesture research process, large collection of functions to map to gesture
ask users to fit gestures to tasks
using Arduino, faster simpler even for a technology company like Nokia
Quantum tunneling sensor, rubber tube that changes resistance linearly when compressed
prototyping is very useful for pushing ideas forward internally and sell to VPs

Sabrina ???, France/London

HITProto tool
when low-fi/hi-fi is not adequate
McCurdy and Schrage => mixed reality instead
allow rapid prototyping and testing of haptic interaction
Scratch (MIT) interface + H3D

???, Belgium

DIY culture, users build their own smart ojects/projects
Building audio instrument with Arduino

Froy Birte Bjornseth

offshore and HCI on board ship
bring multitouch and gesture control to ship navigation
paper prototypes to see gesture for direct manipulation of a ship + interface

Paul Lemmens, Philips, Eindhoven

tactile jacket with 64 actuators (vibromotors)
started testing to reproduce cutaneous rabbit illusion
first prototype, solenoid express
next prototype full body c2 tactors, eventurally use simple vibromotors
enhanced tv/cinema watching experience, like d-box for garment/vest
very nice prototype
???, Belgium

sketching interaction for NFC payment system
co-design and PD
interaction modeling with NFC, gesture, navigation
build simple wooden model where the screen size (both reader and device) is matching post-it notes sizes
very good tip for paper prototyping various options/screens/interfaces


Jonas ???, KTH, stockholm

Angle prototype => learn about angle/geometry for pupils 5-6th grade.
Phantom + Reachin API or H3D, can get something working in couple of days. Heavier stuff needs months maybe.
Conclusions of the prototyping activities

-thinking through the materials
-materials difficult to attach


Monday October 20

Posters and demos
browser plug-in extension providing a heatmap + automatic Table Of Content for web pages
ItchyFeet, mobile social systems geospatial tagging
6DOF mouse
Beat Bearing, tangible rhythm sequencer, Peter Benett

Keynote, Jonas Birgersson

(network)2 = internet, reduce friction on a historic scale
“the stupid network is a good idea” (David S Isenberg)
now IP is everywhere
“the value of the network increases with n2 per node” (Robert Metcalfe)
from 2 types of design good/bad to 4: perfect/good/bad/evil
perfect design: robust, balance, counter evil



David McGookin

touchscreen usability for visually impaired users
touchscreen problems: innaccessible, no tactile, can’t browse/select
touchscreen pluses: generic UI, infinite possibilities, cheap/commodity
2 techniques to compare: gesture player and buttons players
conclusions: gestures problems, no sight touch relation, took longer as you have to be more careful
conclusions: buttons problems, lack of travel, button sizes and spacing
use the edges of the screen to design gesture…

Marigo Heijboer, Eindhoven,

Keeping up with appearances

Jeanine Kierkels

map qualities to artifacts with different hardness

Tomas Lindroth, Göteborg, Sweden

breadcrums of interaction
study of laptop use during class/teaching
etiquette of laptoping
device merge/blur different contexts
like Hansel and Gretel, we leave traces behind
deliberate but ephemeral trails
can we use this better? how? constant breadcrumb of our computing activities

Heekyoung Jung, Indiana

Ecologies of Artifacts
personal inventory, 105 items of interaction artifacts
constitution of digital artifact
properties (inherent to object): physical, interactive, functional, informational
values (accumulated over time): emotional, experimental, social
connection through functions

Jenni Anttonen

Bodily response to virtual faces, pressure sensitive chair
bodily movement and motivated behaviours
EMfi chair, TAUCHI project, Tampere
stimuli of virtual agent/avatar
cover story told (measuring body temperature) when it was actually not

???, SICS

pieces of identity
“if you have nothing to hide you have nothing to fear”
Orwellian society
a project where information about guest were gathered, then presented during a social event (party) at SICS
guests had rfid tags and could explore the their profile at a station
screens displaying who is on the dance floor

Usable Security

in the end, it boils down to users have to behave securely
possible to have feel unsecured even if acting securely



Turkka Keinonen, professor Helsinki

UCD and fundamental needs
pockets of design that are more meaningful and ethical
i.e. ucd but now a business asset nowadays
3 needs:
drive behavior: desires
achieving something: instrumental
essential/elementary: fundamental
Frankfurt “making things better is less important than avoiding things that are worse”

Ticket to talk television
TV + presence + social for the elderly
see what your social friends are watching. support pre and post watching activities


Tuesday October 21

Posters and demos
aesthetic as personality
C3 tangible sequence
3D interaction, see-through display
talking about hearing
comba, modular mobile devices design

Keynote, Gerhard Fischer, University of Colorado, USA

Transcending the unaided individual human mind
digital bauhaus (P.Ehn)
social production (Benkler)
democratizing innovation (Von Hippel)
mass collaboration

1) distributed intelligence
dimension: spacial (wikipedia), temporal (learning from the past), conceptual (symmetry of ignorance)
communities of practice
2) meta design: design for designers
design time vs use time
create context instead of content
not only build/design/plan technology structures but social structures

Audio Photography, 3 seconds press => audio recording of the scene

Audio augmentation for museum installations
directional sound on circle (IR detector)

Alex Taylor, Pottering by design

character of home
studying home life

critical sketches:
-growth detector
-pottering scheduler
-plant care monitor
