  1. 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. 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. 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. 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. 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. 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. 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. 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.
