From the book “Interactivity by design – Creating & Communicating with New Media”, Ray Kristof & Amy Satran

1. Remove obstacles

– Let people interact with the content as directly as possible
– Give them simple routes to the information they are looking for

2. Minimize effort

– Keep related controls close together
– Put frequently used buttons in places that are easy to reach in relation to other items on the screen

3. Give feedback

– Feedback should be both appropriate and immediate (for example, responding to mouse clicks with a sound and highlighting items that have been selected)

4. Be explicit

– Make it obvious what is clickable on the screen and what is not. Objects that look like buttons should act like buttons. If images have hot areas, make sure they are distinct from the rest of the image

5. Be flexible

– Make all media (sounds, movie , animation) interruptible
– Make it easy to quit at any time, from anywhere, by using the computer’s standard keyboard shortcuts for quitting

6. Be forgiving

– Don’t create conditions where users have to “do the right thing” before they can move on

interaction_continuum.jpgThis continuum represents the range of possible user interaction and specifies the kinds of things that users can control. It’s a vocabulary of interaction that can help you express your goals in basic terms.

Rich interaction: Moving towards a more natural interaction through the use of intuitive actions to manipulate digital information.

Gesture-based communication in Human-computer Interaction

Integrating “disappearing” computers and multi-modal interfaces into a natural environment

Physical participation and experience in the human-machine interaction process

Gestural Human-Computer Interaction: Moving towards intuitive experiences for the manipulation of digital information


The way people use and interact with a product is as important as what the product can do or what it looks like. The current state of human-computer interaction (HCI) is confined to traditional Graphical User Interfaces (GUI). The interactions with these GUIs are limited to keystrokes and mouse clicks. Limiting man-machine interaction to keyboard/mouse input and text/graphical output means employing only a small fraction of the overall interaction bandwidth that is available to us. My approach is to use multi-modal interfaces that will allow the artificial system to engage in a similar dialog with the user, with the objective of exploiting the richness, robustness and flexibility of face-to-face conversation.

Secondary research already conducted in the fields of augmented reality and interaction design reveals the need to broaden Human-Computer Interaction by exploring more communication channels and the use of intuitive human actions. Further studies will be undertaken in the form of observations of how humans interact with seven applications ranging from low to high degree of interactivity. By the use of video capture, three variables will be measured: physical kinesthetic, temporal dimension and responsiveness. Following the interactive experience, a survey will be undertaken so that users can describe their experience in terms of ease of use, learnability, system adaptability, etc. From my research I hope to understand the unmet needs of users when it comes to communicating with digital systems.

My approach will focus on an integrated design of real and virtual worlds. The resulting hybrid environment provides and requires new forms for interacting with information. The idea is to augment everyday places and objects with information processing capabilities. I believe that augmenting the physical environment with computer-based devices providing new functionality will provide a much richer multi-sensory experience of digital information. The proposed project explores the use of intuitive actions to manipulate information. The idea is to move towards a more fluid and natural interaction. The concepts presented will also demonstrate new potentials in navigating content without the fear of information overload associated with it.
