Tacit Knowledge
The kansei function covers the process inbetween the tacit knowledge and explicit
knowledge is the kansei function.

Explicit Knowledge

Objectives of kansei research are,,,Understanding the intuition and expression.

good relationship between tacitknowledge and explicit knowledge.
Tacit Knowledge

Support thinking with fundamental research ofmind.
All these for create the good relationshipbetween tacit knowledge and explicit knowledge.

Since the establishment of Kansei Engineering, themethod had been applied to design development.
At the 6th ADC, 2003, there were a lot of
research presentations on kansei and design.
The application area of kansei research had been
expanded to marketing, communication, product,environment, graphic, architecture, culture,
lifestyle and more.

The elements of the kansei research had been
extended to:
Subconscious mind function, cognition, feeling
evaluation and brain function.
Application of the kansei research had been
extended to:Marketing, promotion, communication, design.
As a science of mind, kansei research mustcontribute to the research and development indesign.

structure of Kodawari
Kodawari (obsessiveness)related to personal
preference and intuitive
decision.
Categorizing manner may
show the unaware sense ofkodawari.
A person with strong
kodawari weights not only
functional part of product but
visual or esthetic elements.

expression of kodawari
Balance of number ofgroups, number of groups
include preferred productmay show the difference oftendency between designeducated and others.
Assuming designer isgenerally having strong
kodawari, this result shows
the difference of kansei.

behavioral analysis oftea friends
Tea set is not only a functional
object provide drinking tea. It also
modify the communication
environment.
Experiment of different situation:with tea set / without tea set.
If somethig different, it shows theclue of effect of unaware object forcommunication．
Generally, panel takes tea at thetime of break of conversation andend of speaking for seven seconds.
In case of drinking at silence, ittakes 20 seconds.

tea set and communication
Behavioral analysis of timedependent changes of distance in
two person was made incomparison of with tea andwithout tea.
Characteristic pattern of change ofdistance had found.
10-30 seconds in [with tea]5-10
seconds in [without tea]
Effect of tea set support closenessof relationship and stability ofcommunication.
Tea drinking situation, tea produces
more close positioning. At the sametime, it make easier for people totake timing and relaxedcommunication.

summary
Kansei information study gives uscomprehensive information of mind process, notmind reactionKansei information will support fundamental
understanding of human’s mind and designers’
mind
Kansei science will be the necessary element indesign, similar to the fundamental study on
cognition in 1980s.
