Introduction

Introduction : More about …

• A family of sports• Requires navigational skills using a map (and

sometimes a compass)• To navigate from point to point, and find control points

(indicated on a given prepared orienteering map)• The objective is to follow the fastest route between

controls (/!\ the fastest is not always the shortest route and can depend heavily on route choice)

• Currently no solution to follow runners on a small zone (GPS => not sufficiently precise)

… Orienteering

3/23

A Project was born …

• Idea of the O!Secour software born 4 years ago • Idea from Pierre Le Lagadec, Physical education teacher here at INSA, and

Xavier Le Guillou, former student from the Computing Department

The Idea

• During an Orienteering race, teacher is far from students :• - The teacher can’t intervene if a student gets lost• - An injury quickly becomes very serious

• Only 2h of P.E. per week, no time for students arriving late• Pretty much impossible to write down an individual or collective report

An answer to a need

• A tool that would give a real-time individual and collective safe follow-up, and allow to make an easy, quick and efficient report

Conclusion

Partnership with BTS Students• In charge of the electronical part of the system :• 3 components :• - CM• - ERPI• - ORP

BTS Students from Lycée Reaumur, in Laval

• Transceiver has to :• - Receive GPS data from all erpi• - Receive data from orp• - Receive indivual distress or help signals from an erpi.• - Transmit an error signal to an erpi.• - Transmit an individual and collective imperative comeback message to one, several or all erpi.

• Locate all erpi• -all, continuously, with a 5-meter-accuracy

CM : A self-powered portable unit, used by the teacher at the departure/arrival of the race (cm = centrale mobile)

• Transmitter has to :• -Continuously transmit location to the main unit.• -Ponctuously transmit a « message received », distress or help (for instance) signal

• Receiver has to :• - Receive a « message received » signal• - Receive a « Guidance error » message• - Receive an imperative comeback message

ERPI : 16 to 24 individual portable transceivers (erpi = émetteurs/récepteurs portatifs individuels)

• Has to transmit to the main unit the location of the control points with a 5-meter-accuracy. Used by the teacher when placing the control points.

ORP : A tool to check control points (orp = outil de relevé pour les postes)

O!Secour software

• A software was then created, to receive data from the runners’ erpi, and display them

• Software realised with a specific language (Tcl-Tk)• It includes a map editor and a track editor

The software as it is …

• Now missing a real-time application, displaying, thanks to GPS coordinates sent by the ERPIs, the runners onto a map in a panel of the software

• Need some optimisation also (design/functionalities)• At the time, radiowaves were used, but not working properly

in the forest, so now has changed to GSM transmission

… and how it has to be

• To convert an existing map into a located map

Aim

• a click on the map to define a point• GPS coordinates input (related with the point)• deletion of a point which have already been created• modification of already input coordinates

Basic operations

• image size (about 2 Mo)• format (.jpg, .jpeg, .gif)

Input, an image file

Map editor

Map editor(3)

10/23

Map editor(2)

• a map as an image• an XML file which defines GPS coordinates

Outputs (editor returns)

• <map name="STR">• <picture name="STR" width="INT" height="INT"/>• <topleft x="GPS_COORD" y="GPS_COORD"/>• <bottomright x="GPS_COORD" y="GPS_COORD"/>• </map>

Track editor

• create/modify/delete a start, control points and indications associated to these control points.

• create graphically an ideal circuit and give an estimation of the associated distance.

Aims

• An XML file• A map as an image file

Inputs (generated by the map editor)

13/2313/23

Track editor(2)

• addition of start (red triangle) by click or coordinates• start modification (by drag’n drop or coordinates) • start deletion• addition of a control point (red ring) by click or coordinates • control point modification (by drag’n drop or coordinates)• modification of the index related to a control point• control point deletion

Main operations

• an XML file• a bmp file

Outputs

Real time applicationSpecifications

Real visual heart of the project

Application has to :

• Save runners’ data• Manage chronometer• Display positions/tracks• Display messages from runners• Allow the teacher to send messages to runners

Real time application Interface details and functionalities

Race visualisation :• Race generated by race

editor with its control points

• Runners represented by a colored square and the runner’s name or ERPI

• Tracks followed by runners and the ideal track

• Data saved to a debriefing application

21/23

Real time application Input/Output statements

• An XML file that describes the race• Another XML file giving a description of the map• The map itself as an image file

Inputs

• A new XML file to generate statistics on runners, on their performances, etc.

Experiences and the Project Mr Le Lagadec’s

presentation

• Global vision• Software• Language used : Tcl-tk

Xavier Le Guillou’s point of view

• Tcl : Scripting language

• Tk extension : Graphical interface

• Coding : Code made by hand(Mr

Le Guillou) Use of a code generator

(student)

Why did they choose to use this scripting language ???24/23

Advices

Advantages : • Tk extension : easy

to use • Tcl : handheld• The “event loop” !

Disadvantages :• Learn a new Language

What are the other characteristics ?

> Research by ourselves

25/23

Our Knowledge

Learned at INSA :

- Java

- Perl Scripting language

- C language

Some researches :

- TCL : Tool Command Language John Ousterhout , 1988 - Interpreters : Tclsh and wish

- Analysed some scripts

26/23

Conclusion : Adopted solution

• Program by ourselves > Educational experience

• Use TCL-TK : It seems to be the best alternative

• Mr. Le Guillou has proposed to teach us the main features of the language
