The Eye Tracking Laptop Video Presentation

 Yesterday I briefly talked about the Laptop that integrates eye tracking.

Today I found an 'official' video that shows the eye tracking in action. Here it is.

 

 

The video certainly is interesting. Some of the things I briefly mentioned in yesterday's post are demonstrated.

I enjoyed the demonstration and I honestly think it has potential. However, I don't know if I could really get used to letting my eyes substitute my hand/mouse movements. The reading/scrolling looked promissing and that certainly would be a valuable tool for all you readers.

 

So, are you convinced?

Eye Tracking comes to the laptop

 Eye tracking has been around for more than 100 years and the technique and technology have come a long way since then.

Soon enough, it will evolve once more.

The idea had been around for a while but it appears that the 'Eye Tracking Laptop' has finally arrived. 

 

Tobii partnered up with Lenovo and created a laptop with integrated eye tracking control capabilities. They believe that the functionality will work hand-in-hand with the traditional keyboard and mouse...without necessarily killing them. 

 

The eye tracking laptop will be able to track and analyze a person's eye movements and elaborate suggestions based on where the user looks. They exemplify with the possibility that if a person looks to the bottom of the screen, the task bar could appear. Or, if the eye tracker notices that a person is stumbling around a certain word, a definition of that same word could appear. They also sepak of the possibility of interacting with characters in games using eye movements. These are two of the many possible capabilities.

 

Pricing? Yet to be disclosed. 
Current Tobii Eye Trackers are valued at around €20.000, give or take a couple thousand. Barbara Barclay of Tobii states that the laptop eye tracker could be much cheaper.

 

In short, this little piece of technology sounds great. One can only wait to launch an FPS and start killing some aliens with their eyes!

Portugal's Political Crisis

During the last two weeks, over here on Europe's western frontier, the Portuguese political class has done nothing but talk of the PEC and the PPC.

The 'PEC' - 4th of its kind -, an acronym for 'Programa de Estabilidade e Crescimento' or a 'complicated' translation for 'austerity plan', was rejected yesterday by the portuguese parliament. Keeping his promise, the prime-minister José Sócrates resigned, defending the idea that without the PEC, he wouldn't govern the country. His 'abandoning ship' has opened doors to the PPC - Portugal's Political Crisis.

I could go on and on... and on and on... and on and on some more about what I think of Sócrates' decision; how irresponsible it was for all government opposition to merely reject the austerity plan without proposing any valid solutions; how much the opposition's eyes glowed with the idea that FINALLY they could regain power.

I don't like to think that I support a particular political force. I like to listen, observe, reflect and then decide... as well as criticize if I feel I need to.

I don't want to make a habbit of bringing politics to this little corner but after all, this political crisis affects us all. Well, mostly the Portuguese citizens... but I'm sure there are other countries that do share some interest in what's happening over here.

So why am I reflecting on PPC? Simply put, because it looks like once again, the country is in a mess and as concerned citizen, a student, a researcher, a person who wants to build a life here... things don't look promising.

Unfortunately this isn’t a game where we can hit the reset button and start from the beginning. Too bad, huh? It kind of feels like we’re in the middle of one of those ‘horror’ movies… struggling for air, trying to stay alive. Maybe I’m being too pessimistic. But you know what they say: when you’re a pessimistic person, any news is good news.


Do they say that?

'Strenghts' and 'Weaknesses' of Eye Tracking

One of the many sections my thesis will focus on is - as the title indicates – the various ‘strengths’ and ‘weaknesses’ of eye tracking.

From my (hopefully) growing experience, all I can really say right now is that eye tracking has both ‘good things’ and ‘bad things’. In an interesting piece of work, Robert Jacob and Keith Karn [1] present a listing of several authors’ views on the ‘value’ of eye tracking. The common idea found: eye tracking is ‘promising’.

My search on the internet in attempt to find a few opinions on the subject was semi-productive. I did find a couple of interesting contributions:

Is Eye Tracking Worth It?’ by Jim Ross
http://uxmatters.com/mt/archives/2009/10/eyetracking-is-it-worth-it.php

Eye Tracking: Worth the Expense?’ by Jared Spool
http://www.uie.com/brainsparks/2006/06/13/eyetracking-worth-the-expense/

Eye Tracking the User Experience’ by Mark McElhaw
http://www.spotlessinteractive.com/articles/usability-research/eye-tracking-the-user-experience.php

 

Based on my brief analysis of each contribution, I developed this table why summarizes some of the main (not all) ideas that 'stood out'.


 

Description

Strengths

Help identify usability problems             

Show hard to articulate behavior

Visualizing data for observers

Provide compelling visualizations of usability problems

Video-based eye tracking equipment is becoming relatively inexpensive

Better visualization and analysis tools are becoming available

Evaluating efficiency of systems where visual-motor reaction time is crucial.

Analysis of tasks where traditional usability testing methods have indicated a problem that eye tracking might clarify

 

 

Weakness

Eye Tracking Can’t Track Peripheral Vision

Fixations don’t represent attention or understanding

Interactions between facilitator and participant change

Eye tracking Can Be Intrusive

Eye tracking Tests Take More Time

Eye tracking Is Expensive

Eye tracking Can Be Difficult to Learn

Eye tracking Is Subject to Technical Problems

Not Every Participant Can Work with an Eye Tracker

Labor-intensive data extractions

Difficulties in data interpretation

 

Hopefully this will be of some help for those who are working on the same subject.

If you’re just dropping by and happen to know where I (we) can find more valuable information on the subject, please let me (us) know J
