This post is trying to answer some of the most common questions that we get asked – Why should I buy a Tobii? Why is it better? System “X” has a “better head box” and system “Y” is cheaper.
The answer from our point of view is simple, the eyetracking is more accurate than using other systems for more people over a longer timeframe.
This is a pretty grand claim, why are we so confident?
Let’s start at the beginning; Eyetracking itself is straight forward, there are several well documented methods to find and follow the pupil, Tobii uses a non-intrusive video based technique called “Pupil Centre Corneal Reflection” (PCCR). Essentially an IR illuminator is used to help differentiate between the pupil and the iris, it also creates a highlight or glint that we use as well. The Tobii systems use an improved version of this idea, the secret-sauce as it were being a combination of two things, illumination and data modelling. These two areas allow the remote and wearable trackers to monitor the respondents relative 3D position in space, adjust the calibration parameters in the 3D physiological model, and therefore afford a far greater range of movement than similar systems while keeping accuracy and precision.
(Figure below shows the native 3D data from the TG2)
Illumination: Tobii can use up to two different lighting techniques known as bright and dark pupil to optimise the illumination for the participant in that location, and crucially when they move we can adapt the illumination to keep track of them. This allows a Tobii to offer people greater freedom of movement while retaining the tracking accuracy without the need for constant drift correction from the system operator.
Data modelling: The Tobii method is different having typically used multiple cameras in their research grade eyetrackers and have done since the launch of the T and X series systems in 2007/8. The advantage of using multiple cameras is that we can physically describe the location of the eye in space. That is to say we know with a very high degree of accuracy where the centre of your eye is, and which eye it is, for every sample recorded. The slightly different images from the pair of cameras in an X2 for example allows the creation of a 3D physiological model of the eyes it is tracking during calibration. This approach allows Tobii to understand the movement of the eye or the eyetracker should one or the other move and adjust the calibration accordingly with a high degree of precision.
The net result is that the these systems can accommodate movement, even if the head leaves the area trackable by the hardware and can recover tracking when the eyes are visible again, this is one of the reasons people keep choosing Tobii for demanding applications like infant research and in-vivo commercial research. In a recent study Acuity Intelligence recruited 330 people as they were entering supermarkets and didn’t have to turn away a single participant because they could not be tracked – a first for any data collection exercise with this number of people regardless of the brand of technology they were using.
Don’t just take out word for it, please challenge us, whether it is onscreen, in the real world or in the emerging AR and VR application areas we can help.

As part of the evolution of the Tobii Glasses 2 software platforms we are happy to announce some new functionality released and available now!
Event Logging in the Tobii Pro Glasses Controller We have added the possibility to log live events in the Pro Glasses Controller software. This enables you to highlight interesting parts during the recording. The events can also be exported, together with all the other data collected, into the Tobii Pro Glasses Analyzer software.
Time of Interest Feature in the Tobii Pro Glasses Analyzer The latest release of the Pro Glasses Analyzer includes the option to segment data by creating custom portions of it. With the Time of Interest feature, you can choose a start event and a stop event to get a clearly defined set of data for a particular event. Also, we added the possibility to view logged live events, created in the Pro Glasses Controller, to be able to find the interesting parts of the recording and use these when creating Times of Interest.
Other improvements in this release:
- New quick-access menu
- Possibility to resume Real-World Mapping by storing all queued automatic mapping tasks when closing the program
- Major performance and stability improvements for big projects, where some operations are 10+ times quicker

The Tobii Glasses 2 have been a huge success, with the wide angled field of view, live wireless viewing and automatic slippage compensation thanks to the unique 4 camera binocular tracking more and more people are able to do some great fieldwork both unassisted and in a more traditional context. However as with all glasses based eye tracking platforms the analysis of the data is more time-consuming than with a screen based system as you need to code the user data onto reference images to create aggregated visual outputs and statistical metrics. This can be very time-consuming and depending on the type of interactions mapped (fixation or raw data) combined with the environment and task of the user (unboxing a product, retail purchases, driving and so on) can take anywhere from 10 to 20 times the duration of the recording to code – so 100 minutes of total recorded interactions could take upwards of 16 hours to code before you can begin the analysis.
Tobii Real World Mapping can help reduce this time considerably in many types of study by using advanced computer vision to automatically detect the gaze points based on the reference images you upload – meaning that 10x or 20x multiplier comes down to as little as 2-5x, and processing can be queued so the software can happily run along in the background freeing up valuable staff resources to focus on other tasks.Once the automatic process is completed you are presented with a chart plotting the automatically mapped points, alongside a confidence level in its accuracy and then any missed points (for example if there was a large amount of occlusion in the frame) or mapped points that need some adjustment can be manually corrected by a researcher.
This video has a brief overview of this exciting feature which will be part of next update of the Tobii Glasses Analyzer software.
Of course not every single study will be able to take advantage of the new functionality, for example very dynamic content such as sports science studies have few or no fixed reference points to work with, objects that are largely occluded constantly or are at extreme distances will not be viable but for a large number of shopper studies, product interaction, mobile and tablet applications, advertising and navigation tasks users should see a significant time savings to using the tool – and by running a pilot (see tip 28 on Tim’s Acuity Intelligence blog for a reminder of the importance of this : http://www.acuity-intelligence.com/blog/eye-tracking-tips-26-30) you can quantify this benefit and also ensure that your reference images are correct and work well – more about that another time!
The Real World Mapping is ready to demonstrate to customers now – so get in touch and we will be happy to walk you through it, and show how it can help you process your glasses based eye tracking data quicker!

Today Tobii and Acuity are proud to announce the next generation worn eye tracking system. The Glasses 2 platform succeeds the hugely popular Tobii Glasses and is the culmination of years of research and development, interviewing and understanding customer needs and takes advantage of the very latest technological developments.
There are several key issues raised when we discuss glasses based eye tracking systems with our clients :
- Does the frame feel natural and does it interfere with peripheral vision?
- What is the field of view of the system, can I track everything the customer looks at?
- What is the glasses slip or they move them?
- Can I read what they are reading?
- Can I watch what they do during the testing, like I do with my screen based eye tracker?
To answer question 1 take a look at the image below, showing the new Glasses 2 frame, the arms and design are very similar to a normal pair of spectacles, the lenses are clear, with no large frame to restrict vision or blinker you into looking forward. The eye cameras are mounted very discreetly in the arms reaching down from the bridge, so not only are they a clear and crisp design, they don’t obscure your field of view, don’t blinker your peripheral vision (essential in driving / sports / shopper studies) but the user will also be less conscious about wearing the frame in public, meaning more naturalistic behaviour.
So we move onto the field of view of both the scene camera and the eyetracking data. Until now mobile eye tracking platforms have used 1 or 2 cameras (either monocular or binocular) to track the users eyes, Tobii have gone with 4 cameras, two per eye and the benefits are immediately obvious. By having two cameras per eye you instantly have a much wider degree of movement on each eye that can be tracked, not only that but by using Tobii’s patented 3D eye modelling the system can also compensate for slippage of the frame – something that has been a curse of eye tracking studies when shoppers move the frame, sports people move quickly or when testing with children who interfere with the frame. Of course being able to track a wide range of movement is not good unless we can visualise the data on the scene camera video, and here we see a huge 675% increase in the number of pixels over the Glasses 1 platform, meaning that the camera is running at a HD resolution of 1920×1080 pixels. To ensure that the field of view that is tracked maximises the rest of the platform, the camera field of view has been vastly improved to give 90 degrees diagonal FOV, around 25-30% larger our competitors products, the un-obscured frame also means that users have a visual field of view of 160 degrees – so testing is more natural, across a wider field of view in every dimension!
With this increased field of view, high definition camera and dual camera binocular tracking mobile testing, packaging, reading studies and more all spring to life with the moderator being able to see every interaction, and this can also now be done live via either a cable or wireless connection to a Windows PC or tablet – opening up endless possibilities for testing, and the ultimate in flexibility. With the basic system allowing for post testing recording via the recording device the entry price point is incredibly attractive, and users can upgrade the system as their needs evolve.
So the 5 key questions we get asked are all ticked off and Tobii haven’t stopped there, there is a new gaze mapping platform allowing for aggregated data across multiple participants, visual and statistical outputs and A/B comparison testing. There is also of course a microphone to record user audio, the scene camera has been angled to ensure that close interactions are captured, a gyroscope and accelerometer embedded for future development and interactions and of course world class eyetracking accuracy and precision!
We are expecting to ship units in October so please contact us to arrange a demo or for more details or visit http://www.tobiiglasses.com.

Why 2013 Is Going To Be Even Better For Our Clients…. February 5, 2013Posted by Natasha French in eye tracking, Market Research, Shopper Research, Technology, Tobii, Uncategorized, Updates, Usability & UX.

It’s been a busy couple of years with exciting developments here at Acuity. Key to this was the launch of Acuity Intelligence just over a year ago and the addition of Technical Director Dr Tim Holmes. I’ve had a few clients contact me, curious to find out the difference between the two companies: Acuity ETS and Acuity Intelligence (ETS and AI for short!). Reflecting on 2012 and what it held for the group, I thought the New Year might be a good time to clarify the difference between both and explain why 2013 is going to be even better for our clients.
Most of you reading this will already be aware of Acuity ETS. You’ll know our Directors and hopefully come to us when you have an eye tracking sale / rental requirement. Alongside this, ETS also offer training and support, giving you the tools and ‘know how’ to complete your own independent research effectively and use scientific technology to answer difficult commercial questions.
Now, if any of you know our Directors well, you’ll also be very aware that they are technology geeks (this enthusiasm is a must for anyone that joins the Acuity team!). With a (slightly obsessive) thirst for new tech, it wasn’t long before other tools that could supplement gaze data were also found by the guys. Wanting to offer these to clients too – the idea of Acuity Intelligence began!
Customer tracking / counting technology, facial and emotional recognition solutions, non-intrusive biometric sensors, browser based eye tracking to name but a few, the supplementary offering expanded quickly along with the AI team.
The end of 2011 welcomed a new company Director and Vision Scientist, Dr Tim Holmes. Actively involved in scientific research as a university lecturer, Tim was the catalyst for AI offering additional research and consultancy services based on real science. Services which include education about why technologies such as eye tracking and galvanic skin response are important measures of consumer attention and emotional engagement; the design of rigorous and innovative research projects that maximise the value of client investment by using the right combination of methodology and technologies to answer client questions; and innovative analysis and presentation of results that are scientifically accurate, replicable and focus on the meaning of the data, rather than just the numbers themselves. With Matlab and E-Prime consultancy offerings, AI also supports experiment development and data analysis in a number of Universities in the UK and beyond and is actively involved in cutting edge research at a number of institutions. In addition to all this, AI now also has product integrators and software developers in house who are feverishly beavering away on some truly unique off-the-shelf solutions as well as bespoke solutions tailored to the needs of specific customers!
Working together for you in 2013
Both sister companies offer something very different but both work together seamlessly on your behalf to provide you with a more complete research solution for 2013; all equipment rental, technical support and analysis or simply the technology and knowledge that will enable you to complete your own independent research well. We hope that by extending our offering to you, we can offer a more flexible way to make use of new technologies that add real scientific value to your research.
