Eye Tracking the iPad With Tobii Glasses July 21, 2010

With the recent launch of two great products, the iPad and the Tobii Glasses, we have of course received huge volumes of enquiries about combining the two. Tobii themselves have posted a video online of the Wired app being tested, so we thought why not have a look at a couple of sites ourselves. There is no specific test in the example video below, more of a general browse of the website using the glasses but you get the idea of how flexible the Glasses can be. Holding the device can be natural, no stand or clamp required, and I can orientate the device as I see fit. The unique interface of the iPad, including its pinch zoom functionality is a far different browsing experience than on a PC (not to mention ‘Flash-less!’) and something that more clients and UX consultants are aware of and are building and designing with in mind. For more information on the Tobii Glasses you can check out our new page on our website (http://www.acuity-ets.com/products_glasses.htm) which gives you an overview (although mostly about shopper interaction) or give us a call on 01189 000795 or drop us an email at sales@acuity-ets.com where we will happily answer any questions, discuss your options and arrange a demo.

Technical Tip For Studio – Audio Synchronisation July 13, 2010

We have had some isolated reports of issues with audio sync problems within certain operating system / set-up combinations, and although many of them are fixed by altering drivers or settings this little tip fr0m Guy at Simple Usability (www.simpleusability.com) is more generic and should be an easier fix for most people. Thanks to Guy for bringing it to our attention.

What is Audiodg.exe?

The audiodg.exe file made its appearance in Microsoft Vista, which explains why I haven’t seen this file before. When I viewed the properties of the file, the description stated Windows Audio Device Graph Isolation, which doesn’t help explain what it does.

After doing a little research I found out that the audiodg.exe file hosts the audio engine for Vista, and from what I hear Windows 7 as well. All the DSP and audio processing is performed within this file. Vendors are able to install their own DSP and audio effects into the audio pipeline, which will then be processed by audiodg.exe.

Unfortunately, this can also lead to some problems, as I experienced. Some audio effects can consume CPU and memory if not properly coded. How do we fix the problem? Lets take a look.

Disabling Audio Effects

In order to fix the high CPU usage, I disabled the audio enhancements processed by the audiodg.exe file. To disable the audio enhancements, use the following steps:

  1. Right-click the speaker icon in the lower right corner.
  2. Select Playback Devices from the menu. A list of devices should appear on the screen.
  3. Double-click the device that has a green checkmark. The properties windows for that device should open.
  4. Click the Enhancements tab at the top.
  5. From the list of enhancements, uncheck all of them, or click the Disable all enhancements checkbox.
  6. Click the OK button to save your changes and close the window.
  7. Click OK to close the Playback Devices window.

We often get asked what resources are available for getting the latest news on eye tracking and usability, so I thought I would add a couple of items here that I look at regularly, although Twitter is of course a great minefield of information to sift through…

From our friends over in Australia we have the very active blogger and social media lover James Breeze of Objective Digital, there are a couple of feeds here, one eye tracking, one more general UX and the other a link to his very active Twitter feed : http://objectivedigital.com/blog/our-blog.html 

Of course Tobii have their own blog which is updated by the training team guys and is here : http://tobii.posterous.com/ 

If Whitepapers and academic reports are your thing there is a list of over 200 here using Tobii systems : http://www.diigo.com/list/tobiieyetracking

On Linkedin there are a large number of groups to join, the Eye Tracking Group, MR groups and so on – these are great forums for posting questions, getting feedback from other users and more.

If videos are your thing then YouTube has a huge resources of eye tracking related videos, look for the AcuityETS page, or search for Tobii and you will probably find something to demonstrate what you are looking for!

And finally for this (ongoing) list is a Twingly channel set-up by our friend James in Sweden…. Twingly is a news feed and this collects blogs, post and news on eye tracking in one resource : http://www.twingly.com/eyetracking

Feel free to add any suggestions for more – drop me a mail at jon@acuity-ets.com

Just a quick line to all customers with a valid support contract the Studio 2.1.14 is released, and tested by us here at Acuity and we recommend you install it now! Simply go to CHECK FOR UPDATES, from the HELP menu in Studio and download the file. Recent Studio releases improved the video export functionality with an additional codec that saves time and has smaller output sizes and tweaked the audio sync amongst other things.

If you don’t have a valid support contract contact sales@acuity-ets.com or give us a call on 01189 000795 to discuss your options to ensure you don’t miss any new features and functionality.
