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.Its a fact of life embedded systems need human interaction. With some systems, so much work is invested in the HMI that its 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.

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.

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.

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.

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.

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.

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.

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.

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.
