Who we are, what we do

RE:Lab in brief (promise)

(C) Copyright 2009-2010 RE:Lab s.r.l. - Strictly Confidential 07/05/2010 4

The core business of RE:Lab is the Human-

Machine Interaction.

Our aim is to improve the relationship between

people and technologies in order to make the

products and services of our customers reach

higher levels of quality and competitiveness.

In order to achieve such goals, we have

created a mix of ergonomics, usability and

technical knowledge that we call Interaction

Engineering.

RE:Lab is a UNIMORE (www.unimore.it) start-up.

Interaction Engineering


Human Factor experts and engineers work

side by side to define new methods and to

create new technologies to support our

work and our customers’ one.

Thanks to this combination of knowledge

and skills that expresses the interdisciplinary

nature of this company, RE:Lab operates in

several fields, such as automotive,

agriculture, earth-moving machineries,

manufacture, household appliances,

biomedical.

Expertise


In order to pursue our aims

with efficiency and efficacy

we have organized our

competences in 3 functions

and a structure for projects.

HMI for the Automotive Domain

What are we talking abut?


How similar, how different

07/05/2010 11

» The Automotive domain actually encompasses different kinds of vehicles.

Though easy to think of, the whole category is tricky to capture:

Means of

transport

A work tool

An emotional

tool

Four Wheelers – from the outside

Urban Extra-urban In the wild


How similar, how different

07/05/2010 12

» HMI must be tailored around the tasks each vehicle is meant for;

» …but costs are usually an issue

Means of

transport

A work tool

An emotional

tool

Four Wheelers – from the inside

Urban Extra-urban In the wild


So, when designing HMI for the Automotive…

07/05/2010 13

» All of these factors affect the whole process (regardless of the specific

project):

» Type of vehicle: purpose and related tasks

» International Standards (e.g. ISO 15008, ISO 26022)

» Local laws

» Human Factors / usability best practices

» Market structure and trends

» Customer profiles

» Branding

» Previous manufacturer’s experience

» Time to market

» Budget


Case Study #1

The Racer


The Racer

07/05/2010 15

» He (rarely “She”)

» …seeks sensations and emotions

in driving

» …asks for the top of anything

» …is very self-confident about his

own driving skills

» …often overrates his own

» …wants also interfaces to be

dynamic

» …likes innovation to be visible

too, and to let it show

» …can afford it

Source of requirements:

• The Branding / Marketing area

• Top Customers visits

• Reports from maintenance and

after sales service

• Reports from test track tests

Activities focus

Layout optimization: information allocation basing on functional area definition activity.

Bitmap rendering optimization for target hardware (Graphical Library generation).

Information readability: font sizing, background/foreground contrast optimization.

Graphical information representation to enhance information meaning.

Setting structure: list model design (fisheye model) and visual affordances to physical input device.

Information management: information format suitable for different contexts.

Interaction design: design and development of 2 conceptual models (one for each device).

Affordances system design implementing “old Ferrari mechanic gear changer metaphor”.

Prototype development. Devices drivers development and integration with

prototype model. Haptic effects software development and integration with

prototype model.


Case Study #2

The Farmer


The Farmer – Needs and Requirements

07/05/2010 22

» The Buyer and the User may not be

the same person!

» A tractor is a working tool, more than

a means of transport. The user wants

any system on it to be:

» Easy to read

» Simple to operate (“push one

buttons”)

» Trustworthy (“the more it does on

its own, the better”)

» The buyer wants systems ito:

» Improve efficiency

» Prevent errors

» be self-explanatory


• “Customer clinics”

• Interviews

• Reports from maintenance

» A knob-based control device

was introduced allowing the

user to manage and quickly

set the system functions;

» this system is expected to be

particularly appreciated in a

working context that is heavily

affected by vibrations and jolts.

Case Study #3

The Traveller


The Traveller – Needs and Requirements

07/05/2010 34

» He / she is a heavy traveller, often has

several meetings scheduled on the same

day. The car is one of the main working

tool, and an effective navigation systems

is therefore not an option. But it has to…

» …support the driving task in a clear

way

» provide information when and in the

way it is needed

» …prevent unwanted consequences

such as:

» being fined

» being delayed by roadworks /

accidents

» Crashing due to distraction


• Interviews with travelling

sales people

• Benchmark of OEM

navigation devices

• After sales reports

Case Study #4

Everyone


Everyone – Needs and Requirements

07/05/2010 38

» Everyone as a driver would like his/her car

to…

» …keep him/her aware of vital

functions

» …present information effectively and

simply, as referred to

» Performance

» Consumptions

» Emissions

» …tell him/her only what’s needed

» …be easy to learn, or no learning

needed at all

» …be consistent with his/her own style

» …eventually know him/her


• Market trends:

• in-vehicle systems

• smartphones

• Mass customization studies

• Our experience as drivers


BlueDashTM concept

Today people carry iPods and

iPhones into vehicles to manage

and listen to their own music.

With BlueDashTM

we do more:

we carry vehicles into iPhones.

It’s the conjunction between

people and vehicles worlds.


BlueDashTM architecture for vehicles

CAN

Analog & Digital I/O

Apple protocol


BlueDashTM platform

Upload V01

software and

firmware version

on App Store.

Download V01 BlueDashTM

iApp from App Store.

BlueDashTM

equipped vehicles.

No further hardware

reconfiguration is needed!


BlueDashTM platform: new vehicles

V02 works correctly with scooter,

city car, bike and sport car.

No further hardware

reconfiguration is needed!

Upload software

and firmware

version on App

Store.

V02 overwrites

V01.

Automatic software and firmware download.

BlueDashTM

equipped vehicles.


BlueDashTM technology advantages

1. The in-vehicle ECU is low-cost and easy

to place thanks to its small size.

2. In-vehicle ECU hardware could be stand

alone or it could be integrated with

other electronic systems.

3. The in-vehicle ECU is self-configurating

on the network and once installed it will

never be touched again! Firmware

updates will be transparently managed

through the nomadic device.

4. High data security level thanks to cifred

Bluetooth transmission.

5. It is possible to set different access levels

(read only, administrator, etc.).

6. Platform allow the development of

professional services and applications.


Suitable for all models

For vehicles equipped with

CAN network, BlueDashTM

could manage and provide

all data coming from the

network (e.g. speed, rpm,

fuel, consumption, etc.).

For vehicles not equipped with CAN

network, BlueDashTM

could manage and

provide analogic data (e.g. battery

tension).

Example: Speed via GPS


Application scenarios: OEM opportunities

BlueDashTM

enables OEMs to implement real

added value services.

» Service/dealer localization for

maintenance and service booking.

» Vehicle data collection and

communication with operations centers.

» Digital user manual.

» OEM or other manufacturers’

aftermarket components promotion and

selling.

And much more.


Application scenarios: create customers communities

Create customers networks and communities, improve brand sense of

belonging.

Brand initiatives

Customers clubsSocial networks


Application scenarios: look&feel customization

Customers can customize their own device with different graphical skins.

New skins can be uploaded on the App Store and could be easily

downloaded.


Other potential application domains

Sportive applications

» High range sportive applications

» Performance control

» Advanced settings



Off road

» Orientation

» Off road trip information



Automotive

» Virtual Dashboard

» Vehicle control

» Safety

» Green driving

» Diagnostics
