Technology Trends: Eye Tracking

Eye tracking is a technology that is becoming more and more popular for use in software evaluations. Eye tracking makes use of infrared and other types of sensors to detect and track where a user looks while working. Modern eye tracking equipment can be mounted underneath the computer screen to face the user, or can come in head-mounted configurations. Eye tracking studies typically involve task analysis of one type or another, with the goal of capturing what users saw while they were completing their work. Analysis of eye tracking data can reveal which parts of an interface a person spent the most time using, which parts they missed entirely, and which areas of an analytical graphic were studied the most to inform analytical conclusions.

One challenge associated with eye tracking is that it generates a tremendous volume of data in a very short amount of time, so often there is substantial effort involved with analyzing the results of eye tracking studies. Using eye tracking along with other common usability methods (talk aloud protocols in particular) is quite popular, as eye tracking can provide insight into what someone was looking at, while verbal reports and other methods can reveal what the user was thinking at the time.

The first video I'd like you to look at, Tobii 4C Eye Tracker Review, is a short demonstration on how eye tracking works and what some of the common outputs look like.

Welcome back to another review from kit guru tech I'm schlip and today I'm going to be taking you through the Toby eye tracker. So I'll do a slight unboxing and then what I'll do is I'll take you through the use of it and what it can do and my initial thoughts on it. There's also a feature and here where I'll show you where I went from some of the i60 and spoke to representative there. This is how I actually got my hands on this and she'll take you through with specs and so on. On to the unboxing.

 

Hey I have this snazzy little device. How good does this look? What wait, unbox it okay unless I have to. So let's get the cardboard out and right pup it to one side. It's the Tobi eye tracking Toby eye Tracker, which is the 4c edition. So obviously this slides out like this. There's the outer and this a little lip break so it's a lot of sticky seal. There it says void. Oh dear have I broken something? Nope, so it comes in a foamy packaging as you can see here. And this is the Tobi eye tracker itself, so the foam padding have to be tracker itself, with a 1 meter standard USB cable so I believe that's the only connection you have for it. Look at it itself, it does have two white lines here which I know are to sync up on the screen of your monitor.

So when you set it up using the software that we provide it gives you two lines at the bottom the screen which you match up so it can centralized itself. The rear of this is magnetic, and there is magnetic strips inside,they look like this. They can attach to different devices, you have the ability to attach them to two different devices, so if you have a laptop under your desktop monitor sorted. So they go for there, there's a simple instruction manual inside also, and the rest just requires you to download there the Tobi App.

 

So we're let's get started and move on to that. Now over to sign up and install in the device. So like I say it's as simple as plugging a USB to and in a magnetic strip to the bottom of your monitor or laptop. And then who can hold up. The setup process actually takes you through a tutorial where these lines here become more clear as to what their use is, because you have to centralize them at the certain point of the screen. So I won't go through that now but basically you just add the Tobii eye tracker device the bottom of the monitor, find a USB 2 port that's available, I have one on my keyboard luckily, and plug it in.

 

Obviously you can see the software at the right hand side doing this job, and you can set up profiles. So when I'm looking on this now, it's actually going to move for me so you can follow my finger to where I'm looking. So if I come on here and follow my finger down down down down there you go. So gauge trace so you should be able to click on gauge trace there we go. So I'll sit here so you can see and you should be able to see the gauge trace on the screen. There you go top left bottom, left bottom, right top. right well now you can see that or not. So obviously that little ball on the screen thar is everywhere I'm looking now. And hi you're allowed to experience turbulent tracking in gaming, There we go as you can see, I'm reading that the autopilot is on. Activated infinite screen so it has head and eye control. So I should be able to tilt my head in my eyes and move little bits and bobs and so on, but basically the aim of this is to destroy the asteroids before you cut into them. So obviously everywhere I look now, it's going to shoot.

 

And my opinion it's out about two millimeters, but when you're playing on games so on so forth it's not really that much of a difference . And it's not meant to replace a mouse say for instance, it's meant to be mouse assist. So say you're on two radi, and obviously in different games you have of body and head control movements. And this can control head movements more than body, but as you can see, there's a lot of asteroids here. And I'm trying to kill through and as I do find it difficult to maintain my Gaze, which is a key factor to play in This. And put there we go so no asteroids hitters we did a good job. There we go but that's pretty much all the ones available. And all of it there with Luke I press the spacebar. Pressing exit to leave so you go all the way to the right turn your head to look down press spacebar to exit. And there we go. So that's a simple setup and that's the simple were introduction to what it offers.

 

Moving on my opinions are obviously it's not bad to replace the mouse, but mouse assist is fantastic. And possibilities for people with some sort of disability, which doesn't allow them to play games, with the correct movements of the hands. It could progress into something like that, and it's a slight step into VR. And it's nothing to do with the vibe of the oculus or anything like that. An option like I say it's an option to step into the VR sort of style world . You don't get the full immersion but you get part of immersion. You can have an infinite display and you can just use your eyes to do things like that. And onto normal gamers and like I did say Tomb Raider and Lara Croft. When shooting and it does use AI assists so if I wanted to look in the direction, I could still use the mouse to move the body, and I still use the keyboard to move my feet, or if I wanted to move the gaze so it locks on to like an eagle, or locks on to and antelope,or a wolf ,or so on, I could just lock my gaze on click and it snaps to it it's fantastic. And it does make that process a whole lot easier and for the price point of150 euros around about. And it's not too bad. I can say if you want an introduction to VR there's other options out there, but this is just more of a new thing. You can also be using office tasks and so on. Obviously the game gaming marketers what they want to try to introduce it into. And there's the fact that it links with just a standard USB cable and it can be moved the peripheral can, and is amazing. They do offer this with in certain Dell Laptops, where it is integrated over to the laptop itself. Obviously you'll pay the premium for that. I think that the peripheral is a pretty good idea. I'd probably see it more of a bit a gift or something on their minds. Well I could say people with disabilities, say people don't have full control to their right or left hand and they don't want to use the mouse or can't use the mouse,this does offer an option to not use them. With everything else we'll just go through the clip now where I was at and so many I was talking a representative and let's take you through the CPU usage and so on.

 

So let's Go. So Christine explain to me what we got here on the bottom of the screen. ( Christine) Yes we have the Tobi Eye tracker in the Alienware 7 laptop. The tracks your eyes in current life, Just tell where you're looking has about a director has an eye tips and in it goes has about lumbers and CBO low it's really nice. We have a peripheral as well. And we have it in about 50 games, we have for example can we really hop through one? And we have it in ghost speaking violence, dying light, in greater, and more games coming soon. Tomb Raider give me panic attacks and she falls off everything, I feel like I am falling off with her.

 

On to the next bit, if I was to buy one, and I wouldn't say I'd stretch my ear of enthusiasm or stretch my attention span for very long, unless they keep coming up with new updates. And there is quite a few games to go under the bolts so game assists so on. And but I can't see this being something I'd be overly excited use on the daily day-to-day basis. More when I have friends around or I wanted to show it off so on, And that's just my opinion. If it's something that you can use creatively or you can use because you have a disability or you can find any use of it on a daily basis then fantastic. But the thing for you for me personally I can't see myself using it in that way to its max potential. And but on that note I've been Schnitz this is kick guru tech, and if you like what me and Leo do then please like and subscribe. And this should be a description below with a link in that goes direct our website. And please go over there and take a look any pictures you want to see or any more information made on this review otherwise like I say I will see you later, love you goodbye, [Music] English (auto-generated)

Next, I'd like you to look at another short video, Tobii Pro Website Usability test, describing how eye tracking can be used specifically for usability studies. Both videos this week are from marketing materials, so keep that in mind as you watch. Please note that there is no audio.

Video: Tobii Pro Website Usability Test (1:41)

Eye-tracking software is heavily used in cartographic research to understand how map readers visually interact with the map. An example of this research is discussed in this short article. And to see an eye tracking recording of map reading, see the video below.

Video: Providing Gaze History for the Orientation on Small Display Maps (3:10)

This video is silent. The images and text are described in the link below.

Click here for a description of the video.

Someone is scrolling and zooming and moving around a map on a phone. Text on screen says “Where is the nice place I have seen 2 minutes ago?”

Ever got lost on your mobile phone map? GeoGazemarks will show you where on the map you have looked at.

Person wearing a set of VR glasses and looking at a phone with his finger getting ready to touch the screen.

The eye tracker tracks where you spend visual attention. On high zoom levels fixation points will remind you where you have been looking at. When zooming out, these fixation points are clustered, providing you an overview of your map usage.

Screen captures of a high zoom-level map exploration Gaze recording Fixation computation. The size of the dots showing zoom level indicates fixation duration. The low zoom-level overview map has no gaze-recording but does include fixation clusters. Size of dot indicates the number of fixations. This is a circular process. You zoom in and retrieve previous fixations and zoom out and see cluster fixations.

User study = 40 participants within subjects design. GeoGazemarks vx. Panning and zooming without gaze history.

User study demo shows looking at phone with VR glasses and navigating around a map.

5 points navigation, from point A to point E passing several of the letters and a McDonald's icon. Finally, point E is reached.

Search task: find back to McDonald's.

The clusters are computed from the fixation points on the map. The fixation map is on the screen and you see the person with the VR glasses zooming in and out on the phone looking for McDonald's. They click on several of the fixation points until they find McDonald's.

Results:

The participants performed the search task with GeoGazemarks significantly faster and with significantly less interactions.
