Finding a home

The Luddy School provides a welcoming, diverse environment for learning, but you'll need a place to lay your head. IU Bloomington offers on-campus residence halls and apartments that will allow you to meet fellow classmates, students from other schools, and people from all over the world. Off-campus housing also is available. Find out more about options for living arrangements.

Find out about our Human Computer Interaction (HCI) program.

Description of the video:

HCI brings the human and the computer together and really focuses on how they interact with each other. So what goes on between the human and the computer? Sometimes it's individuals, sometimes it's groups, and in lots of different contexts. In the past, for example, we very much focused on OK, how do I make this technology more usable? Now the field for the last few decades has expanded largely to include also aspects of what we call user experience. Aspects of how people perceived technologies, how they can benefit from technologies in their lives, in their careers and so on. From the human side, you need social sciences, economics, behavioral investigations, anthropology, sociology, and from the computer side, obviously have computer science and mathematics and all kinds of things that go into technology building. That can also be thinking through what kind of institutional structures or what kind of policies do we need relating to these technologies to make sure that they're socially beneficial. The reason HCI is important in understanding the real role and place of technology in our society, is that technology is not just objects and artifacts. Technology is much more than that. And HCI essentially, among other things, provides that broad perspective in terms of what it means to people, what, how it changes and shapes our ways of life. We are living in the golden age of HCI research right now. In HCI, we have faculty across our departments not just within informatics, but across in computer science as well as engineering, information and library science who are working on HCI problems. We have like an extensive number of like health HCI researchers. We have some of the best design researchers in the field. We have people understand the society impact. We had people do privacy and robotic and different ways that people interact with technology. By bringing in a whole bunch of people from different backgrounds, different areas, different countries, different perspectives to try to solve problems together. That's when we learn the most from each other. I think it's an overall theme, also, in HCI and in our department also is thinking about these more ignored populations or marginalized populations. If you have an interest in changing the lives of the left behind populations and making an impact that way, there's no better place to do it. I think in Indiana we have very unique opportunities. The research that we are conducting has a direct reach to this people in rural communities. And they can reach the max impact because they are the people who need this kind of solution the most. In a lot of research I do, I study different subcultures. How's it changing the traditions they're used to, right? Technology might be disrupting their way of life. If the model with which the systems are built comes from the Western world, that may not necessarily fit how they're used outside of the Western world. So that's why we need research that looks at all of these things. The research questions in a sense are endless because I think both human computer interaction and human robot interaction are fields that are trying to invent the future as they go along. The research at IU is going to be very progressive and pushing the boundaries of what HCI is about. The next big technology that's going to emerge requires studying people, understanding what their needs are, what challenges they face. And from that, you can extrapolate and build the next big thing that's going to solve that problem or address that need. We can do things now that we would've never been able to do five or ten years ago just based on the technological savvy of the population and the technological capabilities of that continue to drop in our lap every single day. When I think about the future it's not so much in terms of what machines can do, you know, if machines are going to be able to do this and that and the other, rather, how we should be able to take control about the future of technology and our societies. We can empower people to change their own lives. And by doing that, we're going to be changing society.
Discover new research into Security and Privacy.

There isn't a day that goes by when privacy or security or something related to those aspects is not in the news. Things seem to be, you know, getting out of control for the average person with their identities being stolen and so on. How do we protect our country's networks from being exposed in foreign jurisdictions? There's growing recognition that this is an important problem. It's challenging and it's diverse because it affects not just individuals but societies. Security is classically considered confidentiality, integrity and availability. Confidentiality just means if it's secret, I can keep it secret. Integrity means making sure it's correct. And availability means making sure that I can get to it. We're just now starting to recognize the enormous challenges that we face in the cyber security domain. We have a truly holistic approach to computer security. One that is increasingly embraced, not only by the scientific community, but also by industry and government. I think we're one of the very few places and one of the top places in the country where if you're interested at the intersection of Human Factors and people and how they use systems and security. This is one of the places where we do that really well. Indiana University in security has been top ten for the past five or six years. So what's exciting for me is that I can work with, for example, psychologists to understand how do people make photo sharing decisions, can work with sociologists to understand what are the implications for privacy of people in our groups as we share photos on social networks? And I can work with computer vision researchers to understand ways in which we can identify sensitive content and photos and detect them automatically. The larger view of security as including organizational, human, and economic, as well as engineering, networking and mathematical components is what distinguishes us. We also have a mission to do cutting edge research on the most challenging and latest problems of today. The demand for cybersecurity professionals of all different kinds is just skyrocketing and we don't have enough cybersecurity professionals. Many of our students have gone on to work at a very respectable places, right? Like Microsoft research as an example, and Google and so on. It's an exciting time right now to be studying cyber security and privacy and security aspects of everyday technologies that everyone uses. As a security or privacy student and researcher, you have the opportunity to make a real difference in people's lives by making the world a safer place, but also a place that's more respectful of people's privacy. Whether your personal strengths are interviewing people, building devices or running the network, there are security questions that need your insights.
