Tech Focus: Designing for connectivity and accessibility

HIGHLIGHTS

Ballmer predicts new era in computing, entertainment, smartphones in final Microsoft CES keynote

Mobile Internet basics: Transport layer mobility challenges

Consumer electronics turn to MEMS for gesture control, precision location

Gesture recognition–first step toward 3D UIs?


Editor's Note

Amidst the cornucopia of new designs and devices introduced last week at the Consumer Electronics Show two trends I noticed were the emphasis on connectivity and accessibility. The connectivity was in the form of ubiquitous wireless and mobile networking and the accessibility was in the form of a variety of touch and gesture interface schemes to make average non-desktop computer users comfortable with the new consumer computing devices.

Connectivity introductions that caught my attention include: Wilocity's WiGig wireless system, LG's nextgen Android 4G smartphone, Broadcom's 5G Wi-Fi chips, Celeno's home Wi-Fi multimedia system, and connected TVs . Consumer devices and technology pushing the touch and gesture accessibility design envelope included Freescale's multi-touch resistive touchscreens , Atmel's nextgen touchscreen MCUs, LG's 3D TV touchscreens , the Invensense 9-axis motion tracker and Greenpeak's motion-sensing remote control units.

At the core of all these cutting-edge consumer devices is a wealth of embedded hardware and software technology, some of which is discussed in the design articles and white papers collected here. My Editor's Top Picks on accessibility topics include:

Gesture recognition: first step toward 3D UIs
The challenges of multi-touch gesture interfaces
Adapting UIs to multiple embedded device display needs.

My Editor's Top Picks for nextgen connectivity in mobile/embedded designs include a six part series on Mobile Internet basics , recent articles on M2M web services on the Cloud , and designing smart sensors for an “Internet of things .

As exciting and revolutionary as the designs exhibited at CES were, I am sure this is only the tip of the creative iceberg and I look forward to contributions from you on both of these exciting areas of development.

Design How-Tos

Mobile Internet basics: Transport layer mobility challenges

In this series, the authors of “Building the Mobile Internet” provide a tutorial on extending Internet connectivity into mobile networking by using extensions of protocols such as IPv4 and IPv6 as well as mobile specific protocols such as DSMIP, IKEv2 and MoBIKE. Part 1: Dealing with transport layer mobility.

Web services puts M2M in The Cloud

Web services are one way to connect devices and sensors to the extended Internet, where objects talk to other objects. Here's a primer on how Web services work for machine-to-machine applications.

Expanding the Embedded Universe: Migrating From IPv4 to IPv6

With the imminent exhaustion of IPv4 address space, and a mounting number of embedded devices pushing the limits, it is time to move to IPv6. Here's how IPv6 corrects three problem with IPv4 and what you need to know to make the shift.

Designing intelligent sensors for use in an “Internet of Things” – Part 1

In this two part series, the author describes how an “Internet of Things” consisting of ubiquitously connected intelligent sensors would work and the MCU and DSP hardware needed to achieve it. Part 1: Basics of sensor design.

How to Internet-Connect your low cost consumer retail embedded design

In this Product How-To design article, Arrayent's Harshy Wanigasekara describes the advantages of Internet connectivity in a wide range of consumer products and how to use Arrayent Inc.'s turnkey end-to-end system to Internet-connect low cost products sold at retail to the World Wide Web.

Designing Wi-Fi connectivity into your embedded “Internet thing”

In this Product How-To, Redpine Signals' Narasimhan Venkatesh provides some basic guidelines to consider when adding Wi-Fi connectivity to an embedded design using a combination of a Cypress PSoC and Redpine-supplied components, including its Wi-Fi Expansion Board kit.

Adapting UI designs to multiple embedded/mobile device display needs

The key elements and approaches needed to build user interfaces to meet the varying display requirements of mobile devices and any embedded system with a display and GUI.

Gesture recognition–first step toward 3D UIs?

Gesture recognition is the first step to fully 3D interaction with computing devices. The authors outline the challenges and techniques to overcome them in embedded systems.

The challenges of multi-touch gesture interfaces

The key to understanding multi-touch touch panels is to realize that a touch is not the same thing as a mouse click.

Using projected capacitive displays to create durable gesture-based touch screen interfaces

How projected capacitive technology can be applied to touch screens in embedded apps where the harshness of the environment might wreak havoc on older resistive touch screens.

Waking up a capacitive touch-sensing device with an MCU peripheral

When a capacitive touch screen goes into sleep or standby mode to save energy, how can you design the system to wake up quickly without degrading its performance or burning a lot of power. Here are two options: a traditional method and a new MCU-based method.

6LoWPAN: The wireless embedded Internet – Part 1: Why 6LoWPAN?

Part 1 of an excerpt from the book “6LoWPAN: The Wireless Embedded Internet” reviews the concept of the Internet of Things – and its subset, the wireless embedded Internet – and answers the question “Why 6LoWPAN?”
