I  will  show  how  we  can  frame  temporal  dimensions  of  our  environments  for  our 
appreciation. In contrast to artworks, environments are changing all the time. There is no 
frame with which to define what is the specific object of appreciation in environments 
which surround us, and which extend without limit. We have to create our own frames 
by ourselves. The question is how we frame temporal changes of environments.
  First, I will classify the changes in two groups: macro- and micro- temporal change. 
We  cannot  directly  perceive  the  former,  but  can  with  the  latter.  Although  we  can 
perceive micro changes, it is difficult to appreciate them because they are so ordinary 
for us that we usually do not pay any attention to them.
  Second, I will introduce Arnold Berleant’s “aesthetics of engagement” to clarify the 
mechanism of framing these micro changes. Engagement is a kind of aesthetic attitude 
for appreciating perceptual environmental experiences which consisted of cumulative 
micro changes.
  Third, I will elaborate on the role of our activity in framing micro changes. I will 
distinguish  our  activities  in  environments  into  two  levels,  and  show  how  aesthetic 
engagement is related to each level.
