Human Computer Interaction in the year 2020 and its Impacts:

Human Computer Interaction in the year 2020 and its Impacts Presented by; Navneet Kaur

Why learn about HCI?:

Why learn about HCI? Utilizing computers had always begged the question of interfacing The methods by which human has been interacting with computers has travelled a long way The journey still continues and new designs of technologies and systems appear more and more every day

Meaning of HCI:

Meaning of HCI Human-Computer Interaction (HCI) is a term used to refer to the understanding and designing of different relationships between people and computers HCI is a design that should produce a fit between the user, the machine and the required services in order to achieve a certain performance both in quality and optimality of the services

Human Computer Interface:

Human Computer Interface Human the end-user the others in the organisation Computer hardware software

History of HCI:

History of HCI Mc Carthy – Father of Artificial Intelligence who invented LISP programming language used HCI for the first time in 1955 The dawn of personal computing in the early 1980s The study of Human-Computer Interaction (HCI) finally took center stage in the mid 1990s World Wide Web, e-mail, and Windows 95 burst upon the scene.

Importance of HCI:

Importance of HCI Productivity individual (e.g. installations, word processing) organisational (changing job content, satisfaction, working environment, power and influence) Safety (e.g. nuclear plants, flight control)

Disciplines, contributing to HCI:

Disciplines, contributing to HCI Computer science Cognitive psychology Social & organisational psychology Ergonomics Artificial intelligence Linguistics Philosophy, sociology, anhtropology

Existing HCI Technologies :

Existing HCI Technologies The existing physical technologies for HCI basically can be categorized by the relative human sense These devices are basically relying on three human senses: vision, audition, and touch .

Vision :

Vision Input devices that rely on vision are the most used kind and are commonly either switch-based or pointing devices The switch-based devices are any kind of interface that uses buttons and switches like a keyboard E xamples are mice, joysticks, touch screen


Audition The devices that rely on audition are more advance devices that usually need some kind of speech recognition Beeps, alarms, and turn-by-turn navigation commands of a GPS device are simple examples.

Haptic Devices :

Haptic Devices The most difficult and costly devices to build are haptic devices These kinds of interfaces generate sensations to the skin and muscles through touch, weight and relative rigidity

Recent Advances in HCI:

Trends in Technologies:

Trends in Technologies Changing Computers GUI to Gestures Smart Fabrics Robots

Changing Computers:

Changing Computers There have been various computer driven revolutions in the past: the widespread introduction of the personal computer(PC) was one, the invention of the graphical browser was another, and the Internet yet another. There have also been computer eras where one type of computer has dominated, having straight forward implications for whether the computers were shared or personal, and for whether they were specialised commodities or not .

PowerPoint Presentation:

Audiovox’s Digital Message Center is designed to be attached to the refrigerator, letting families scribble digital notes and leave audio and video messages for each other.

GUI to Gestures:

GUI to Gestures Used on computers first by Apple Macintosh, and afterwards by Microsoft. The memory and file management are done by the operating system while applications are running – Multi-Tasking. A mouse is used to point and click on icons instead of typing in a command. Dialogue boxes, menus, icons, toolbars etc form the window on the computer screen.

Playful piece of technology is the History Tablecloth, by the Interaction Research Studio (Goldsmiths College, University of London). It is designed to cover a kitchen or dining-room table. When objects are left on the table, the cloth starts to glow beneath them, creating a halo that expands very slowly. When items are removed, the glow fades quickly . :

The HotHand device: a ring worn by electric guitar players that uses motion sensors and a wireless transmitter to create different kinds of sound effects by various hand gestures.

PowerPoint Presentation:

Electronic sensing jewelry(a concept from Philips design) is based on stretchable, flexible electronic substrates that integrate energy supply , sensors,actuators , and display. By changing colour or even shape according to your mood, it explores how wearable technology can be playful , sensual, moodaffected , bio-activity stimulated .  Talk to the hand…From the first mobile phone ‘brick’ to the latest Apple iPhone:as the size reduces, the potential expands

PowerPoint Presentation:

The Reactable : a multitouch interface for playing music. Performers can simultaneously interact with it by moving and rotating physical objects on its surface. Reactable was developed by Sergi Jordà and colleagues at the Universitat Pompeu Fabra , Barcelona. Icelandic songstress Björk used one on her 2007 tour. Sony’s EyeToy being played by grandpa. A camera on the TV projects his image on to the playing screen, allowing him to interact with the game using arm movements and gestures.

Smart Fabrics :

Smart Fabrics Clothing manufacturers have started experimenting with how to embed computer systems using BlueTooth technology. Highend running shoes have sensors in them that talk to portable music players and other mobile devices providing information about how far the wearer has run, and at what speed, helping to update a training log. Medical monitoring devices that can be worn on the body are also beginning to appear that provide dynamic readouts, reporting and alerting us to the status of various bodily functions ( eg glucose level, cholesterol level). Silicon and biological material will be knitted in new ways, enabling new forms of direct inputs and outputs implantable in our bodies.

PowerPoint Presentation:

Animated Textiles developed by Studio subTela at the Hexagram Institute , Montreal, Canada.These two jackets ‘ synchup ’ when the wearers hold hands , and the message scrolls from the back of one person to the other


Robots Robots have been with for us for some time, most notably as characters in science fiction movies, but also as part of assembly lines, as remote investigators of hazardous situations ( eg nuclear power stations, bomb disposal sites),and as search and rescue helpers in disasters ( eg fires) or far away places ( eg Mars). More recently, domestic robots have begun appearing in our homes as autonomous helpe rs.

PowerPoint Presentation:

The Rovio robotic webcam is wirelessly connected to the Internet. It roams around the home providing an audio and video link to keep an eye on family or pets when you’re out. Emotional kitty: a robot hardware platform called iCAT uses a set of logical rules to convey emotional states as it makes decisions, with the goal of improving human-robot interaction. It looks confused if it’s in trouble , smiles if it gets something right…

Extending the Research and Design Cycle :

Extending the Research and Design Cycle

Case Studies:

Case Studies Case study1: Trading versus trafficking content Investigation of the design of services and applications for mobile TV is a case study of how one might use the extended HCI approach . Case study 2: Tracking versus surveillance in families This study looks at the home and considers new kinds of technologies that could be used to enrich family life. The left hand image shows the states that the Windows Mobile device goes through, first showing the file in the process of being received and second, once the file has been received. The right hand image shows the same states on a Symbian device. The Whereabouts Clock: the lefthand image shows the clock in its case; the middle image is a close-up of its interface; and the righthand image shows what happens when you touch on a text message .

Case study 3:The‘value’of augmenting human memory . :

Case study 3: The‘value’of augmenting human memory . This study considers the human values associated with a research topic more generally; namely, how to design new technologies that can augment human memory The Digital Shoebox,by designer Richard Banks of Microsoft Research Cambridge UK, is an attempt to make the storage of digital photos more tangible. Photos can be sent wirelessly to the box, and users can browse through them by running their finger across the top of the box.

Applications of HCI:

Applications of HCI Multimodal Systems for Disabled people Emotion Recognition Map-Based Applications Human-Robot Interface Applications


Conclusion HCI has various applications like Multimodal System for Disabled people, Emotion Recognition,Map -Based Applications , Human-Robot Interface Applications etc. HCI needs to move forward from concerns about the production and processing of information toward the design and evaluation of systems that enable human values that enable human values to be achieved. Quality of system depends on how it is represented and used by user Therefore, enormous amount of attention has been paid to better designs of HCI.
