• Open
– Large development community
• Multiplatform (multi-OS)
– Now on all major mobile OS platforms
– Multi-platform tools (QtCreator)
• Easy to use
– Quick GUI creation with scripting/markup - QML
• Fast
– High performance with OpenGL ES acceleration
– Must be enabled by OS platform
Why Qt for automotive?

5000+ Companies from 70+ industries use Qt From Desktop Applications to
Embedded & Mobile Devices
Qt is Used Everywhere

8 Where are the opportunities for Qt in the car?
• Instrument Clusters & Driver Information
• Infotainment
• Rear Seat Entertainment
• Brought in on a phone (projected)

• OEM Display Growth Opportunity 2012 vs. 2020 – Center Multifunction: +250% (26.5 Mil in 2012 93.1 Mil in 2020) CAGR 17.0% – Driver Information: +1000% (6.6 Mil in 2012 74.8 Mil in 2020) CAGR 35.5% – Headrest: +105% (2.0 Million in 2012 to 4.2 Million in 2020) CAGR 9.4% – Center Roof mount: +25% (310K in 2012 to 390K in 2020) CAGR 2.8%
The Display becomes a key Human Machine Interface (HMI) point for: Audio, Media, HVAC, Telematics, Navigation, Social networking
The Display provides users with a flexible interface tool that will future proof vehicle systems

Reconfigurable Instrument Clusters
Confidential Information of QNX Software Systems Limited
11 Considerations for Instrument Clusters
• Performance
– 60 frames per second for needle movement
– Smooth animations and transitions
• Animation and modeling tools
– Beyond Qt Quick / QML
• Safety
– Emerging ISO26262 functional safety specification
• System level certification
• Focuses on development and testing methods

Rear Seat Entertainment
Confidential Information of QNX Software Systems Limited
13 Considerations for rear seat entertainment
• Segment is getting squeezed
• However, RSE is very similar to infotainment, except
– More content and apps
– No concerns with driver distraction

Infotainment
Infotainment – consumer/platform inversion
•Multi line or small LCD display
•AM/FM/Sat/CD
•Minimal connectivity, occasional Bluetooth hands-free
Low High
• Large screen; Rich UI
• Expansive media experience (AM/FM/CD/DVD/streaming content/iPod/DLNA)
• Smart phone connectivity for media and app sharing
•Multi-modal (voice) user experience

Consumer Expectation
Just make it work like my phone

17 Mobile influenced Ux
• Smooth transitions between screens and animations
• Rich graphical assets (designer driven as opposed to developer driven)
• Multimedia, 2D/3D
• Speech interfaces (recognition, text-to-speech, speech-to-text)
• Cloud connectivity – apps, content, cloud synchronization, dynamic over-the-air updates
• Multi-modal interaction through gestures (swipe, pinch, tap), multi-touch, buttons, speech, …
Bringing consumer technology into the car
• Delivery dates are not flexible – Start of Production (SOP) dates DO NOT MOVE – Huge penalties involved – cars in OEM factory lots without radios: not a good thing
• 10+ year availability (support, services, pricing, parts)
• Fast boot (from complete power off) Splash Screen: < 1 second Early Audio: < 1 second Camera: < 2 seconds Last Audio: < 10 seconds
Fully running and connected: 5-10 seconds
• Automaker control over look and feel – down to their own set of custom fonts
• Driver Distraction considerations – safety, ease of use, cognitive load
• Interoperability with dozens of mobile devices and apps
• Multiple apps, features and connectivity … all working at the same time securely and reliably – Navigation route calculation while syncing USB, while playing music from a phone, while changing
climate control settings
• Robotic CD and USB insertion/removal
• Ignition crank (brown out) and power mode testing

• My Everything – one size fits one
– My Music
– My Calendar
– My Contacts
– My Social Network
– My Weather Service
– My Apps
– My Home Screen

23 Separation and abstraction
UI abstraction layer
Navigation Diagnostics Phone
Media Networking Vehicle Bus
– Intelligence in the UI layer is not a good thing
– Abstraction layer • Allow expansion and replacement
• Loosely coupled
• Allow multiple readers and writers
• Provide change notifications
• Be accessible to multiple HMI environments and programming languages

But not too dumb
• UI is the last line of defense for errors
