Proj-2014-2015-iRock/SRS

1. Introduction

1.1 Purpose of the requirements document

This Software Requirements Specification (SRS) identifies the requirements for the iRock project. This document is a guideline about the functionalities offered and the problems that the system solves.

1.2 Scope of the product

• The purpose of this project is to allow its users to predict and detect landslides and based on information sent by a number of sensors and radios embedded to microcontrollers.

• The code used in this project is extensible and open-source.

1.3 Definitions, acronyms and abbreviations

• LORA : 2-way wireless solution that complements M2M cellular infrastructure, and provides a low-cost way to connect battery operated and mobile devices to the network infrastructure
• SX1276 : A stable implementation of LORA
• Mbed : A platform and operating system for internet-connected devices based on 32-bit ARM Cortex-M microcontrollers
• STM32 Nucleo : An affordable and flexible way for users to try out new ideas and build prototypes with any STM32 microcontroller line, choosing from the various combinations of performance, power consumption and features.
• Keil : Complete software development environment for a wide range of ARM, Cortex-M, and Cortex-R based microcontroller devices.

1.5 Overview of the remainder of the document

The rest of the SRS examines the specifications of the Extensions XBMC 2015 project in details. Section two of the SRS presents the general features of the FollowME extension. Section three outlines the detailed, specific and functional requirements, system and other related requirements of the project. Supporting information about appendices is provided in Section three.

2. General description

2.1 Product perspective

Monitor changes in environment such as temperature, movement, humidity and radio signal in order to detect landslides and predict the possibility of lanslides based on history

2.2 Product functions

This Kodi Addon called FollowMe allow user to change screen while watching a movie or listening to music with Kodi, with minimum interaction and resuming the media. Furthermore, the remote control Android application enable user to add host for the remote only taging NFC tags. It also allow user to write his own tags with host information.

2.3 User characteristics

The user does not need to be familiar with coding or computer science. The only requierement is to be able to share files on a network and to install Addon for Kodi.

2.4 General constraints

• Possece a kinect for the kinect mode
• The device used as remote controller have to :
  • run on Android 4.0+
  • be NFC compatible
  • have wi-fi antenna (mostly all the android devices)

2.5 Assumptions and dependencies

• The android device used as remote controller have a wi-fi access to the network in order to control the Kodi instances
• The Kodi instances are runned on computers on the same network with shared library contaning files that will be resumed.

3.Specific requirements, covering functional, non-functional and interface requirements

• document external interfaces,
• describe system functionality and performance
• specify logical database requirements,
• design constraints,
• emergent system properties and quality characteristics.

3.1 Requirement X.Y.Z (in Structured Natural Language)

Requirement : same version of Kodi (former XBMC) installed on the computers used as screens, our Addon installed on these computers, our version of the remote control application installed on an android device with NFC technology and Wi-Fi, a network between computers and android device, kinect sdk installed on the computers used with kinect mode, NFC tags, files shared on the network

Function: allow user to change screen while watching a movie or listening to music with Kodi, with minimum interaction and resuming the media

Description: an android application and a Kodi Addon to

Inputs: options in the Addon, options in the Android application, number of person in front of a screen, "position" of the user

Source: keyboard or mouse in the Addon option menu in Kodi, ouch screen on the Android device, kinect, NFC tags for the "position"

Outputs: video or sound, depending of the media played

Destination: user(s)

Action:

• play media using network shared files
• resume play of media on various screen
• automatically add host on the remote control Android applicaion thanks to NFC tags

Non functional requirements:

Pre-condition:

• materials conditions:
  • Android device with Wi-Fi and NFC
  • NFC tags
  • computers with screens
  • network
  • kinect (optionnal)

• Software conditions:
  • netwotk between coputers used as screens and android device
  • shared media files on the network between machines
  • same version of Kodi on every computers used as screeens
  • our Kodi Addon installed on the computers used as scrrens
  • our remote control android applciation installed on the Android device
  • kinect sdk installed on computer(s) where the kinect(s) is(are) connected

Post-condition:

Side-effects:

4. Product evolution

• Use of Bluetooth instead of/with the NFC tags
• Find a way to avoid installing Kinect sdk to use the Addon
• Play (a movie or a music) on the remote between two screens using an elegant method
