  • 1. Use  of  the  Wii  Remote  for  Interac2on   in  a  Topic  Map-­‐Based  Learning  Web  Site
 Shu  Matsuura
 Tokyo  Gakugei  University,  Faculty  of  Educa<on,     4-­‐1-­‐1  Nukuikita,  Koganei,  Tokyo  184-­‐8501,  Japan
 shumats0@gmail.com   This  work  tries  to  introduce  a  popular  game  console,  Nintendo  Wii  Remote,   which  is  easy  and  intui<ve  to  use  for  the  interac<ons  with  the  computer  in  the   above  environment.  The  Wii  Remote  naviga<ons  were  implemented  for  a   constella<on  observa<on  system,  a  stereoscopic  molecular  dynamics,  and  the   stereoscopic  Google  Earth.  
  • 2. Summary   A  topic  map-­‐based  online  learning  system  for  science  subjects  at  hPp://tm.u-­‐gakugei.ac.jp:8080/epw/,  Ontopia  navigator  server.       1.  Wii  Remote  as  an  interface  of  web  contents.   -­‐  as  a  pointer  for  real  space:  constella<on  pointer      Wii  Remote  detects  gravita<onal  accelera<on,  so  that  it  can  detect  the  angle  of  eleva<on  from  the   horizon.  We  need  both  GPS  and  magne<c  compass  (iPhone  have  both  of  them),  in  addi<on  to  Wii   Remote,  to  determine  the  posi<on  in  the  sky.   -­‐  as  a  buPon  device  for  3D  space:  driving  a  view  point  for  stereoscopic  display      Mo<ons  of  camera  are  assigned  to  the  buPons  of  Wii  remote,  so  that  one  can  explore  3D  space  using   Wii  Remote.  Stereoscopic  display  s<mulates  observer  to  explore  in  the  3D  space,  and  Wii  Remote  works   as  an  intui<ve  steering  device.       2.  Wii  Remote  as  a  naviga<on  device  of  topic  map.   -­‐  correspondence  between  standard  web  page  design  and  Topic  Maps  structure   -­‐  assign  movement  in        a)  topic  type  hierarchy        b)  type  –  instance        c)  associa<ons        d)  instance  –  occurrences   (reques<ng  corresponding  jsp  file)  to  the  buPons  of  Wii  Remote.     -­‐  then,  one  can  explore  topic  map  driven  web  pages  by  Wii  Remote.    
  • 3. Constella<on  Pointer  Overview  JSP  page  requests   Google  Sky  to  present   corresponding   constella<ons.   GoogleSky Topic  Map  server  Topic  map  server  returns  JSP  page   including  Google  Sky  presenta<on,    Flash  page  requests  the  topic  map  server  to   associated  constella<ons,  etc.   get  the  corresponding  constella<on  page.  A  flash  page  receives  Wii  data,    Input  data  of  posi<on  in  the   and  calculate  the  right  ascension  and   real  sky,  using  WiiRemote. declina<on  of  the  pointed  posi<on  in   the  real  sky.   A  flash  base  web  page  to   WiiRemote communicate  with   “WiiFlashServer”  transmit  data  from   WiiRemote. WiiRemote  to  flash  web  page.
  • 4. Wii  Flash  J   (works  good  for  win,   not  for  mac,,,)   Push  buPon  A  to  get   la<tude  from  google   geo-­‐coding.   Set  la<tude  by   pushing  controller   buPons.   Angle  of  eleva<on  θ  from  the  horizon  is   calculated  by  the  applica<on  from  the   component  values  of  gravity  projected  on   the  three  axis  of  Wiiremote,  gx,  gy,  and  gz. ⎛ gx 2 + g 2 ⎞ θ = −arctan ⎜ y ⎟ ⎜ ⎝ gz ⎟ ⎠ Get  azimuth  by  a  magne<c   compas,  and  set  the  value  by   pushing  controller  buPons.   Get  eleva<on  from  the   ground  by  pushing  the   backside  buPon  B.   g Y
  • 5. Screen  shot  of  sky_pointer.jsp. Topic  map  helps  to  con<nue  to  explore  constella<on   related  subjects. The  values  of  right  ascension   and  celes<al  declina<on  sent   Screen  shot  of  a  constella<on  instance from  WiiRemote Sky  posi<on  pointed   by  Wii  Remote. Links  to  constella<on     instances  included  in  a   range  of  sky.  These  are   retrieved  from  topic  map.
  • 6. Applica<on  of  Wii  Remote  control  to  3D  or   stereoscopic  display  contents. Wii  Remote  can  be  used  intui2vely  for  the  movement   of  viewpoint.  Stereoscopic  representa2on  induces   explora2ve  ac2on  of  the  viewers.
  • 7. Drive  Topic  map  with  Wii Can  movement  in  the  topic  map  be  assigned  to  Wii  Remote  controller  buPons? mode  change:   movement 1.  type  hierarchy   topic  types 2.  associa<on   3.  occurrence Instance  topics inter-­‐field  associa<on movement mode  change:   trans-­‐silo  pathway type-­‐instance  etc. a  retrieved  instance interlinks  inside  silo Instance  topics occurrences resources intra-­‐field  associa<on
  • 8. Topic  map  cons<tuent→  web  design from  aggregated  data  to  distributed  resouces  on  web contents  organized  inside  server(s) informa<on  organized  onto  a  topic  map t o t p o p i c i c contents  in  the  local  server standard  design  of  web  page iden<ty page  header search global  naviga<on Distributed  resources  in  the  internet breadcrumb  trail In  Topic  Maps,  we  have   1)  topic  type  hierarchy  to  organize  subjects,   external,   2)  topic  instances,   local   naviga<on primary  page  content internal   3)  associa<ons  between  topic  instances,   links 4)  role  types,   5)  occurrences.   These  cons<tuents  are  equivalent  to  the  design   page  footer:  contact  inf.,  copyright elements  of  standard  web  page.
