Game UX Summit 2016 – All Sessions Summary

This detailed post describes all the Game UX Summit 2016 sessions, one by one. This event brought together 15 renowned speakers from various UX-related disciplines, from game studios and academia. The keynote speakers were Don Norman and Dan Ariely.

On May 12th 2016, Epic Games hosted the inaugural Game UX Summit in Durham (NC) – which I had the immense pleasure and honor to curate – to discuss the current state of User Experience in the video game industry. This event brought together fifteen renowned speakers from various UX-related disciplines: Human Factors, Human-Computer Interaction, UX Design, User Research, Behavioral Economics, Accessibility, and Data Science. The keynotes speakers were the esteemed Dan Ariely, and Don Norman, who popularized the term UX in the 90s.

Below is my summary of all the sessions (with the edit help from Epic Games’ UX team members – special thanks to Ben Lewis-Evans and Jim Brown!). You can also watch most of the sessions here. The Game UX Summit will come back in 2017: Epic Games is partnering with Ubisoft Toronto who will be hosting next year’s edition on October 4-5, 2017. If you wish to receive updates about the event or if you would like to submit a talk, you can sign up here and be on the lookout for #GameUXsummit on Twitter.

1- Anne McLaughlin, Associate Professor of Psychology at NC State University 
“Beyond Surveys & Observation: Human Factors Psychology Tools for Game Studies”
Watch the video 

Anne McLaughlin kicked off the summit by talking about how a Human Factors method could be applied to measure and manipulate game experiences, without the cognitive biases that inevitably occur when we only use intuition or gut feeling. Signal detection theory, a classic of Human Factors, is one such method. Signal detection measures any game element you want – or don’t want – your players to attend to, such as elements of the HUD, the interface, or icons. Any time players have to make a decision under uncertainty is when signal detection theory can be used to help designers accomplish their goals. Signal detection theory is summarised in the figure below.

The Spy character from Team Fortress 2 offers an example where signal detection was made deliberately difficult (low salience cues) so players cannot easily spot a spy who has infiltrated their team. Anne went on to describe how to use Signal Detection Theory to test the impact of design decisions and shape player behavior. It is generally easy to detect hits and misses when a signal is present. For example, if a Spy has indeed infiltrated the team (signal is present), developers can easily analyze if the player’s decision was correct (hit – identify the spy and shoot) or wrong (miss – not recognizing a Spy is present).  

However, false alarms are harder to detect and design around (e.g. when players believe there is a Spy but there is none) and so are correct rejections, even though these measures are just as important to the game experience as the hits or misses. For example, when developers want to make sure that players do not miss a signal, the tradeoff will be an increase of the false alarm rate, which can lead to player frustration. On the other hand, developers can use false alarms to increase tension, such as in a horror game (e.g. Until Dawn). Therefore, developers should consider and measure false alarm rates to inform design decisions.

In video games, the overall design can drive players to make important decisions. For example, games that offer health restoration and no friendly fire will encourage a liberal response strategy, where almost anything is worth shooting at, thereby increasing the false alarm rate. In games like Counterstrike on the other hand, the design encourages a more conservative signal detection because of the peer pressure of not harming your teammates and the lack of health restoration.

Anytime a person has to make a decision under uncertainty – find a signal in the noise – Signal Detection Theory can be used. So, consciously or not, game designers are manipulating the four quadrants (hit, miss, false alarm, correct rejection) by associating benefits or penalties with each of them. This has also implications on the art direction, because, as explained by Tom Mathews in his 2016 GDC talk, the color of the environment can have an impact on how easy it is to detect enemies depending on what color team they are. Therefore, the blue team or the red team can be disadvantaged depending on how well they stand out.

Anne concluded her talk by pointing out that she is not suggesting that games should be made easier. Rather, the whole point of thinking in terms of Signal Detection Theory is to ensure that gameplay matches with designer’s intent. How easy or how hard is up to them: they control the signal and the payoffs.

 

2- Anders Johansson, Lead UI Designer at Massive Entertainment 
“My Journey of Creating the Navigation Tools for The Division: Challenges and Solutions” 
Watch the video 

Anders Johansson shared some UI design thinking from The Division; a third person co-op experience in an open world with a heavy focus on RPG elements, or – as Anders summed it up – a game where players run around a lot trying to find things. As such, Anders’ talk largely focused on the design iterations that were carried out on the navigational user interface elements in the game.

In early development, the team tried three different map prototypes: one with a top-down camera, one with a free camera, and one with a player-centric camera that used the character as the reference point. Initially they chose to go with the player-centric design because it gave the player a clear reference point to where they were in relation to the world around them through a direct camera-to-world camera mapping.

Johansson said that the UI team thought they had nailed the map prototype at that point, but it turned out to have critical UX issues. One of the reasons for this was that the game that shipped used a completely different camera system than the version that the map research was based on, and these camera differences left many of the map team’s decisions irrelevant or inadequate.

In order to address this, the UI team had to rework the map functionality, and learn to adjust it as the game progressed. As an example of how dramatic the changes were, the camera used to orient itself around the player, but in the shipping build, the map always orients North to avoid any directional confusion. The new map also has contextual  elements (such as buildings) to help the player orient themselves, and the camera can even detach from the character to allow a full-screen exploration of the map. The team decided to remove functionality that allowed the player to run around with the map open because with the new camera system, players could not see their feet anymore. Anders’s core message here was that as a game evolves, the UI has to evolve with it based on the changing results of UX data.

Another challenge Anders and the UI team faced was how to present overwhelming amount of information that was available on the map. There is a lot to do in the game, and without any filters the map would look like this:

To get around this, like in many other games, The Division uses filters on the map. At first, the UI team allowed players to filter each individual map element, but playtest data and eyetracking heatmaps revealed that most players were unaware of this feature, and the players who were aware of the feature reported feeling overwhelmed by the amount of options they had. The UI team tried to find solutions from other games, but didn’t find any that were suitable for their cases until they looked at solutionsoutside of games, specifically from Google Maps which automatically filters content based on the level of zoom. This revelation led to the idea of The Division’s adaptable filter system.

Division-mapfilter

After the core of the map was done and the main features were in, Anders noted that there were still some challenges left to solve. The most important being: what happens when players close the map? How can the game help players find their bearings without requiring them to continually open and close the map? To address this, the UI team tried to give players locational information, such as street names at intersections. Johansson noted that while players were able to read the signs, this method was perceived by players as a slow and cumbersome way to navigate. So the UI team tried adding key landmarks as points of interest (such as the Empire State Building), but this didn’t really work either because spatial awareness works differently in games (where players don’t look around that much and focus mainly on the reticule) than it does in real life. Next, the team gave the player an industry-standard 2D marker to follow on screen, but eye-tracking studies revealed that players did not really see the marker, or lost it quickly when they did see it, because it was not in a central position on the screen. Ultimately, the team decided to try a combination of ideas: they used an on-screen GPS marker that mirrored the marker on the mini-map, that was easier to see, and that included street names.

Anders said that they also added a “breadcrumb system” for indoor and in-mission navigation, that consisted  of a 2D pulsing icon (to draw players’ attention), that moved toward the objective, and that left a trail behind it as it moved.

Division-Breadcrumbs

To conclude, Anders and the UI team tested many UI prototypes for navigation and only kept the most elegant and functional solutions, proving that nothing is easy, and that everything can always be improved.

 

3- Andrew Przybylski, Experimental Psychologist, Oxford Internet Institute
“How we’ll Know when Science is Ready to Inform Game Development and Policy”
Watch the video

Andrew Przybylski presented a metascience perspective in his talk. He questioned how scientific research is carried out and the quality of scientific rigour, both in academia and the video game industry. Using scientific methodology implies that through a systematic view, observation and testing are rigorously conducted to understand the reality we live in and get closer to the truth. Having a hypothetico-deductive scientific process implies starting by generating hypotheses and research questions, designing a study to test the hypotheses, collecting data, analysing and interpreting the data against the hypotheses, and then publishing and sharing the results. This is the ideal of science and how it should work. Przybylski noted that in reality, however, published scientists are suspiciously successful at confirming their own hypotheses. Andrew pointed out that if you look at all these positive findings more objectively, you’ll find that in psychology, neuroscience, political science, cancer research, and many other research fields, studies suffer from a serious lack of replicability.

So why do we have this replicability crisis? According to Andrew, when looking at published work, many studies don’t have enough statistical power to accurately detect a signal in the noise, but often report one anyway. Scientists don’t necessarily do this on purpose though; humans have a natural tendency to perceive a pattern even where there isn’t one. There also isn’t any incentive to publish a research study in which the hypothesis is not confirmed, which biases researchers toward reporting positive findings, or even encourages them to generate the hypotheses AFTER data is collected.

Przybylski said that universities are also part of the problem, because the culture of academia tends to exaggerate research, and then the media exaggerates the findings even more. For example, when a correlation is found, the press (and University PR departments) often make the leap of attributing a causal direction.

Andrew went on to give some advice and guidelines regarding how to interpret “new findings”. For example, if a study has a great story component, Andrew said that it is probably not worth considering. He reminded the audience that scientists and researchers are fallible human beings, meaning that 50% of published findings are likely to be false. If the data from a study is not easily accessible, it is another red flag that the information is likely not valid.

To help improve science, Andrew proposed a special track in several media outlets for pre-registered research, as opposed to submitting an article for publishing only after the research has already been done. It consists of three stages: In Stage 1, researchers provide their theoretical background, hypotheses, research plan, methods and materials, and their analysis plan. Based on this information, a peer review occurs in Stage 2, which can lead to a conditional acceptance of the paper and the registration of the hypotheses. Lastly, in Stage 3, the reviewers follow through on the research. Throughout this process, the data and materials have to be open, and null findings do not prevent the researchers from publishing their study (as is often the case).

Andrew concluded by proposing a few things that everyone can do to improve the state of science:

  • Read Richard Feynman’s Cargo Cult Science,
  • Carefully pilot basic scientific research before investing,
  • Demand and support open science; for example demand not more but better science at GDC,
  • Bring open science into your projects and contribute (a lot of tools today allow you to do that easily).

 

4- Ian Livingston, Senior User Experience Researcher, EA Canada
“Working Within Research Constraints in Video Game Development”
Watch the video

Ian Livingston shared some techniques that he used to apply what he called “good enough” research processes in game development. These techniques focus on providing the highest value to a project, given the limitations of immovable constraints such as budget, resources, and tools.

Ian said that two constraints are particularly important to focus on, those being: can it be done quickly enough to be useful in the fast moving world of game development? and can it be done rigorously enough to be trustworthy? Livingston noted that while balancing these needs may be difficult, the process can be mitigated, and a good balance between these two constraints is what he called “good enough research”.

Doing “good enough” research is not about being lazy or cutting corners. Ian made it clear that “good enough” is about understanding the tools you have at your disposal. How do you decide whether or not to accept a conclusion? It’s all about risk and about how confident you are in the outcome. Once you honestly accept the risk of an outcome being wrong, you free yourself to adjust the level of risk that you are willing to run. If you’re too rigorous, Ian explained, the results are going to arrive too late for the game development team to actually act upon your results, but if your research is done too quickly it might lack rigour and leave too much room for interpretation. As a game user researcher, you want to find that middle ground where the research is done quickly, but also with enough rigour that you have confidence in the results you share with the team.

Ian went on to describe two tools that can be very useful for dealing with research constraints: confidence intervals and eliminating alternatives.

  • A confidence interval represents uncertainty, the grey area about the data you gathered. It helps define what level of uncertainty your team might be willing to accept. Confidence intervals can be calculated using the standard deviation (measured), your sample size (designed, heavily dependent on your constraints), and your chosen alpha (standard, traditionally 95%). Ian said that working in a grey area gives us the freedom to play with these parameters. In the made-up example below, imagine that the development team wants to know if something they changed made any significant difference, so they design a test to measure condition A vs.condition B. They look at the results in one case with an 80% confidence interval, and in the other case with a 95% confidence interval. At a 95% alpha they might not be confident enough to say that the two conditions are different, but at an 80% alpha they might take a riskier bet that the two conditions are in fact different.

  • Eliminating alternatives (rather than attempting to prove an outcome) is what Livingston called being efficient in your analysis. Let’s say a team comes to you to check if the game is too easy because they believe that players have too much health. You set up a test, bring players in, and after they have played, they also tell you that they find the game too easy. You could stop there and go back to the team to say “yes, the game is too easy so you should reduce health”. But this is a lazy way of doing research. If you spend more time researching prior to the test, you can design the protocol to test the different causes that may lead to the perception of the game being too easy. You need to identify a number of alternatives: too much health is one cause, but the players could also make too much damage, or have too few enemies, or have overpowered abilities, etc. so you can design a test that will explore these elements and eliminate the ones that don’t line up. Good research is about identifying alternatives and eliminating ideas that are not supported by data.

Ian concluded by saying that being a user researcher in the game industry is all about balancing rigor against the time it takes to conduct research. For Ian, doing “good enough” research is better than either of the extremes in a constrained environment.

 

5- Education Panel
Jordan Shapiro (Senior Fellow for the Joan Ganz Cooney Center, Sesame Workshop), Fran Blumberg (Associate Professor of Psychological & Educational Services, Fordham University), Matthew Peterson (Co-founder, CEO and Senior Scientist, MIND Research Institute), Asi Burak (CEO, Power Play)

This panel, moderated by Jordan Shapiro, was an informal discussion about using games for learning. Making a great game is tough enough already, so adding another complex layer, learning, usually with a much lower budget than commercial game studios, makes it a particularly challenging area.&
