Introduction

• Name : O!Secour• 2005• Pierre Le Lagadec, Xavier Le Guillou

The Idea

• Teacher far from students• Lost students, injuries• Only 2h of P.E. per week• Individual or collective report => impossible

An answer to a need

• Easy tool• Real-time individual and collective safe follow-up• Easy, quick and efficient report

Conclusion

1. Project & Software1.1 A Project was born …

• In charge of the electronical part of the system :

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

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

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

2. Map and track editor2.2 Map editor (2)

• to convert an existing map into a located map

Aim

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

Basic operations

• image size• format

Input, an image file

3. Run application3.2 Overview

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

3. Run application3.4 Interface details and functionalities (1)

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 for a debriefing application

20/27

3. Run application3.4 Interface details and functionalities (2)

• 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.

4. Means4.1 Introduction

Mr Le Lagadec’spresentation

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

Xavier Le Guillou’s point of view

• Tcl : Scripting language

• Tk extension : Graphical interface

• Coding : Code written by hand

(Mr Le Guillou) Use of a code generator

(student)

Why did they choose to use this scripting language ???23/27

4. Means4.2 Experiences and the Project

Advantages : • Tk extension : easy

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

Disadvantages :• Learn a new Language

What are the other characteristics ?

> Our own research work

4. Means4.3 Advice

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

4. Means4.4 Our Knowledge

Code generator ?

• Program by ourselves : Educational experience

Language

• TCL-TK : the best alternative
