Introduction to exploring HCI
Computers are finding their way into more and more devices, and as a result, HCI is becoming more and more ubiquitous. New technological developments are opening up new areas for exploration Were seeing really fascinating progress in area like virtual reality, augmented reality, wearable devices.
As we study HCI, were going to talk a lot about things youve already used. If youre interested in HCI, youll be designing for these new application areas. So were going to quickly preview some of these. Well divide them into three areas: technologies, domains and ideas.
Technologies are emerging technological capabilities that let us create new and interesting user interactions. Domains are pre-existing areas that could be significantly disrupted by computer interface like healthcare and education. Ideas span both of these: they are the theories about the way people interact with the interfaces and the world around them.
Virtual reality An immersive computer-simulated reality. VR is an entire new classification of interaction and visualization and were definitely still at the beginning of figuring out what we can do with these new tools. VR has application to dozen of spaces: Tourism, Education, Commerce, Art.
For example, there is a lab in Michigan that is using VR to treat phobias (VR therapy and counselling center, Grand Rapids, Michigan) They are creating safe space where people can very authentically and realistically confront their fears The possible applications of VR are really staggering
Augmented reality VR generally works by replacing the real worlds visual , auditory and sometimes every all factory or kinesthetic stimuli with its own input. AR on the other hand compliments what you see and hear in the real world. Devices that can integrate directly into our everyday lives enhancing our reality like Google glass.
Imagine systems that can automatically translate text or speech in a foreign language, or could show your reviews for restaurants as you walk down the street. The application of AR can be truly stunning, but it relies on cameras to take input from the world and that actually raises some interesting societal problems
Ubicomp and wearables Ubiquitous computing (pervasive computing) refers to the trend towards embedding computing power in more and more everyday objects It is deeply related to the emerging idea of internet of things Modern HCI means thinking about whether someone might use computer while theyre driving a car or going on a run
It means figuring out how to build smart devices that also some of the cognitive load from the user, like refrigerators that track their own content and deliver advice to the users at the right time. This push of increasing pervasiveness has also led to the rise of wearable technologies : exercise monitors, smart watches, Google glass, AR headsets, advanced hearing aids
Robotics A lot of the current focus on robotics is on their physical construction and abilities or on the artificial intelligence that underlies their physical forms. But as robotics became more and more mainstream, were going to see the emergence of a new sub-field of HCI : Human Robot Interaction
The first conference on human robot interaction took place in 2006 in Salt Lake City and several similar conferences have been created since then. As robots in the mainstream, were going to have to answer some interesting questions about how we interact with them. For example, how do we ensure robots dont harm humans through faulty reasoning? How do we integrate robots in our social live, or do we even need to?
How do we support humans in teaching things to robots not just programming? Can we create robots that can teach things to human?
Mobile One of the biggest changes to computing over the past several years has been the incredible growth of mobile as a computing platform. This has introduced some significant design challenges Screen is now far more limited Input methods are less precise Distracted users
Mobile computing is deeply related to fields like context-aware computing, ubiquitous computing and AR as it possesses the hardware necessary to complement those efforts.
Ideas
Idea: context-sensitive computing To build good interface between humans and computers, we must equip computers with some understanding of context thats where context-sensitive computing comes in. Context-sensitive computing : equipping user interfaces with historical, geographical and other forms of contextual knowledge. Example: Google maps indicating time to get work during work days Travel reminder .
Idea: gesture based interaction We communicate naturally with gestures everyday, we even have an entire language built out of gestures. So, wouldnt it be great if our computers can interpret our gestures as well? Thats the emerging field of gesture based interaction Example: Microsoft Kinect which has far ranging application from healthcare to gaming
Finger movements can support an incredible number of interactions
Idea: Pen-and-touch based interaction A powerful technique for creating simple user interfaces because it shortens the distance between the user and the tasks theyre trying to accomplish
Idea: information and visualization One of the biggest trends of the information age is the incredible availability of data Scientists and researchers use data science and machine learning to look at lots of data and draw conclusions. But often times, these conclusions are only useful if we can communicate them to ordinary people. Thats where information visualization comes in. Computers give a powerful way to represent data in complex, animated and interactive ways.
Idea : CSCW Computer-supported cooperative work: using computers to support people working together. Distributed teams are just one example of CSCW among others. We can think of design as whether or not were designing for the users in the same time and space or different time and place.
One goal of our good interface is to match the users mental model to the reality of the task at hand in the same way the foal of information visualization is to match the readers mental model of the phenomenon to the reality of it. (a visualization is just a representation of data)
Idea: Social computing Social computing is the part of HCI that is interested in how computers affect the way we interact and socialize From online gaming and wikipedia to social media to dating websites Social computing is really interested in all areaswhere computing intersects with our social life.
Domains
Domain: special needs One of the most exciting application on HCI is helping people with special needs: disabilities, injuring, aging.. Think of robotic prosthetic for example: of course, part of that is engineering, part is neuroscience, but its also important to understand how the person intend to use such a limb and the tasks they need to perform. Thats HCI intersecting with robotics.
Think also about communicating data to blind people: Dr. Walker Sonification lab works in communicating data using sound. A lot of emerging areas of HCI technologies could have extraordinary significance for people with special needs.
Domain: Education A huge portion of designing educational technology is really just straightforward HCI: You might use HCI to introduce some desirable difficulties. Some learning experiences for students. The worst thing you can do in HCI is to raise the students cognitive load because theyre too busy thinking about your interface instead of the subject matter itself.
Domain : Healthcare A lot of current efforts in healthcare are about processing the massive quantities of data that are recorded everyday. There are numerous applications of HCI to personal healthcare like Fitbit for exercise monitoring or myFitnessPal for tracking your diet . Those interfaces succeed if theyre really usable for users.
Domain : Security Weve found people have very little patience for instance where security measures get in the way of them doing their tasks For security to be useful, it has to be usable. If it isnt usable, people wont use it CAPTCHAs are forms to ensure users are humans HCI can make security more usable by visualizing and communicating the need
Domain : Games Games are one of the purest examples of HCI We discuss the need for logical mapping between actions and effects. The actions that the user takes with the controller should feel like theyre actually interacting with the game world. We discuss the power of feedback cycles. If you read about a video game reviews, youll find that most of the criticisms are about bad HCI
