CHI 2015

A summary of Microsoft researchers' papers from CHI 2015 are listed below.

About 70 Microsoft researchers are traveling this week to ACM CHI 2015, the premiere conference on human-computer interaction, to present research results and tools that can do everything from create an interactive, 3D map of your neighborhood to simply deliver you better web search results.

Microsoft’s researchers will be presenting papers, participating on panels, organizing the doctoral consortium and leading plenary sessions at this year’s conference.

The annual conference, which is being held this year in Seoul, comes as researchers at Microsoft and elsewhere are finding ways to make computing even more personal, catering to the very specific needs of surgeons in the operating room, CEOs in far-flung boardrooms and students attending online lectures.

That means figuring out what people need from technology, and also what they don’t.

Take blood pressure monitoring, for example. In one of the papers being presented at CHI, Microsoft researchers asked 34 people to monitor their blood pressure five times a day, in order to better understand whether it would be useful to have continuous blood pressure monitoring in a gadget such as Microsoft Band.

They found that while people were interested in their blood pressure, they didn’t necessarily understand what the data meant.

Dan Morris, a senior researcher who worked on the project, said some participants didn’t trust the readings if results went against their own perceptions of their health, or were really different from a previous reading.

Participants also were likely to draw conclusions about their blood pressures that weren’t necessarily accurate. For example, a person who got a high blood pressure reading might blame it on a recent salty meal, Morris said. While high salt intake in general could have an effect on blood pressure, it’s unlikely that one meal will cause an immediate spike.

Some participants also reported that just the act of monitoring their blood pressure made them feel stressed and anxious.

The reports’ findings reinforce the idea that even though technologies are evolving to the point that they can give us continuous health data about things like weight and blood pressure, that’s not necessarily the best thing for the user.

“It’s not the Holy Grail in and of itself,” Morris said.

Making search work better for you

In the field of search, researchers also are working hard to figure out how to understand a person’s intent when they make a search query, and provide the most relevant results.

“Although we have made tremendous strides in improving the quality and capabilities of search over the last decade, we are still just scratching the surface of what we can do,” said Susan Dumais, a distinguished scientist and deputy managing director of the Microsoft Research lab in Redmond.

In her CHI keynote, Dumais will describe how large-scale behavioral data, such as the queries that people give and the results they click on, are transforming the way in which researchers understand search behavior. That’s also allowing them to design and evaluate new search algorithms and interfaces.

Although behavioral data provides a great deal of information about what people are doing, it provides little insight about why they are doing it, or whether they are satisfied. Dumais said that’s why it’s important to use complementary methods such as field observations, laboratory studies and panels, to get a more complete understanding of, and support for, search.

The field of search also must evolve to be more responsive to new technologies, especially mobile devices. For example, a person typing a search query into a computer screen might use different language than someone who is speaking their request on a mobile phone. That’s because spoken queries tend to be longer, and people use more natural language than when they are typing. The search technology needs to understand they still might want the same thing.

At the same time, Dumais said, people have less patience for technology that doesn’t deliver the results they want right way.

“Today, people just expect search to work, and their expectations about what search can do are growing,” she said.

A more personal meeting

In some cases, making human-computer interaction more personalized means using technology to replicate the kinds of experiences we have when we don’t use any gadgets at all.

ImmerseBoard is a huge touchscreen for virtual collaboration

That’s part of the logic behind ImmerseBoard. It’s a Microsoft technology that uses huge touch screens called SurfaceHubs combined with Microsoft Kinect cameras to let two people standing hundreds of miles apart look at each other, virtually “shake hands” and even write on the same white board.

The interactive, 3D technology replicates the feeling two people have when they are standing next to each other in a conference room chatting about a project. That allows for much more natural interaction than the often-awkward conference call or video chat.

Of course, the technology also adds plenty of bells and whistles that your regular conference room white board can’t.

For example, if two people are in one room, it uses face and clothing recognition to figure out who is at the white board at any given moment, so it can later separate out who wrote what on the board. In addition, it can distinguish between right and left hands, so you can use one as a pencil and the other as an eraser, and it lets you do things like use your finger as a laser pointer from far away.

“We can make meetings more personalized,” said Yinpeng Chen, a senior research software development engineer at Microsoft who is helping to develop the technology.

Microsoft’s presence at CHI this week also includes the following papers and presentations

A framework for automatically generating interactive tutorials: Researchers at Microsoft, Cornell University and the University of Washington are presenting a system that would automatically create step-by-step tutorials, which could be used for things like educational games.
