- 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

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.
