	Dennis Kelly dkelly@qnx.com Breaking up is hard to do Contrary to the title, this paper is not about romance. It is about embedded software design and how to avoid professional heartache.It’s a fact of life – embedded systems need human interaction. With some systems, so much work is invested in the HMI that it’s easy to lose sight of the fact that the system exists for the purpose of performing work! This paper will deal with life-cycle issues of embedded systems requiring an HMI. Read More... February 2016 Download Tina Jeffrey tjeffrey@qnx.com Building Flexible, Future-Proof Infotainment Systems New smartphones come to market every month, and new mobile apps come out every hour, whereas infotainment systems must operate for 10 years or more. So how can an infotainment system designed today work with phones or apps created tomorrow? There is, of course, no single connectivity solution to address the problem. An infotainment system design must therefore possess the flexibility to accommodate the inevitable evolution of the mobile market. The alternative is early obsolescence. Read More... June 2014 Download Tina Jeffrey tjeffrey@qnx.com In for the long term: what HTML5 means to the auto industry HTML5 has become the most widely supported platform for mobile app development, giving auto companies access to a vast pool of developers and applications. It is also OS and hardware neutral, enabling companies to avoid vendor lock-in and to choose platforms that offer the greatest speed, reliability, or flexibility. Moreover, HTML5 can work in concert with other HMI technologies. Developers can, for example, build an HMI with a native toolkit and blend it seamlessly with HTML5 content and apps. Read More... February 2014 Download Scott Pennock spennock@qnx.com In-Vehicle Spatial Auditory Displays: Reducing reaction times, errors and cognitive load Spatial Auditory Displays (SADs) can help provide both a more agreeable and a safer driving experience. Among their benefits are reduction of reaction times, errors and cognitive load. By providing drivers with auditory clues that associate different activities and instructions with specific locations, spatial auditory displays help drivers “intuitively” identify speakers, the sources of instructions, and even the location and relative trajectory and velocity of danger.

August 2012 Download Andy Gryc agryc@qnx.com Kerry Johnson kjohnson@qnx.com HTML5-Hardware Communication with PPS Messaging HMIs developed with HTML5 reside in a high-level, virtualized environment but often need to access hardware. Writing specific interfaces to communicate between the HMI and each low-level service is costly. A better approach is to use an HMI-agnostic messaging model such as Persistent Publish/Subscribe (PPS). PPS provides a simple and effective way for the HMI to communicate with low-level components and the vehicle hardware. Read More... June 2012 Download Andy Gryc agryc@qnx.com Marc Lapierre mlapierre@qnx.com Why HTML5 Is Becoming the HMI Technology of Choice Information about HTML5 ranges from the W3C documents themselves to business cases, evangelists’ musing, and seemingly innumerable how-to articles and tutorials chock full of code samples. This whitepaper attempts to bridge the gap between the musings and the tutorials, and present an overview of HTML5 that will be useful to people who are not HTML5 experts, but who are technical enough to understand what we mean by, say, a chromeless browser.

June 2012 Download Kris Cieplak kcieplak@qnx.com Rapid Development and Reusable Design for the Connected Car In-vehicle systems, and the connected car in particular, bring a host of new challenges to the manufacturing process. These challenges include aligning HMI design with multiple vehicle line branding requirements, safe integration of new applications and technologies, and protecting critical processes in a dynamic system. This paper briefly describes some techniques available for meeting these challenges when designing and building a connected in-vehicle system. Read More... July 2010 Download Andy Gryc agryc@qnx.com Digital Instrument Clusters: Technical Challenges, Market Opportunities Automakers are migrating to digital instrument clusters to reduce costs and enhance the market appeal of their products, while continuing to equip their vehicles with displays that present the vehicle's vital signs in an intuitive, immediately digestible fashion. This paper describes some of the requirements for building digital instrument clusters, and suggests some innovations enabled by this technology. Read More... April 2009 Download Kerry Johnson kjohnson@qnx.com Using Time Partitioning to Ensure Guaranteed Access to Industrial Control Systems An "always on" HMI is a key requirement for many industrial control systems. Nonetheless, the HMI can become unresponsive or unusable under heavy CPU loads. This paper explores how system designers and developers can use CPU time partitioning to prevent this problem and guarantee both local and remote operator access. With time partitioning, developers and system designers can allocate a guaranteed portion of CPU time to each software subsystem, regardless of system load. Read More... February 2008 Download Paul Leroux paull@qnx.com 3D Graphics: Adding a New Dimension to Your Embedded System As a vendor-neutral, multi-platform API, OpenGL ES lets developers reuse 3D code in new projects or across an entire product family. An OpenGL ES application can run on multiple graphics chips and operating systems; it can also migrate from a low-cost system that uses software rendering to a more expensive system that uses a 3D acceleration chip. Better yet, code developed in OpenGL ES can subsequently migrate to a high-end system that uses full OpenGL. Read More...
