What  is  Wearable  Compu=ng?  

Seven  aTributes  of  wearable  compu=ng  [Steve  Mann,  1998]:    1.   Unmonopolizing  of  the  user’s  aTen=on.  User  can  aTend  to  other  events.  2.   Unrestric2ve  to  the  user.  Allows  interac=on  while  user  carries  out  normal  

func=ons.  3.   Observable  by  the  user.  As  the  system  is  being  worn,  there  is  no  reason  why  

the  wearer  cannot  be  aware  of  it  con=nuously…  but  this  contrasts  with  1!    –  BeTer  phrasing:  User  can  iden=fy  computa=onal  and  non-­‐computa=onal  

components  of  their  clothing.  

4.   Controllable  by  the  user.  User  can  take  control  at  any  =me.  5.   A<en2ve  to  the  environment.  Can  enhance  the  user’s  environment  and  

situa=onal  –  Awareness.  

6.   Communica2ve  to  others.  Can  be  used  as  a  communica=ons  medium.  7.   Shares  the  same  physical  and  situa2onal  context  as  the  user.

Example  

•  Wearables  for  sports  training  •  Karate  trainees  are  instrumented  with  

accelera=on  sensors.  •  Sensor  data  is  translated  directly  into  

sound  output.  •  Trainees  can  now  ‘hear’,  as  well  as  see  

instructor’s  movements.  •  Trainees  can  also  hear  themselves:  

aTempt  to  match  own  sound  to  sound  of  instructor.  

•  Mar=al  arts  training  is  about  reproducing  paTerns  over  =me,  not  just  matching  sta=c  poses;  therefore,  sound  is  a  useful  sensory  s=muli  to  introduce  to  training.  

•  Result:  Trainees  with  system  tended  to  learn  faster  than  trainees  without  system.
