Topic 2: Interaction Types
Dear Readers,
Welcome back to our
blog J !!!
Last week have seen the
good and bad examples of applications based of usability goals and objective.
To ensure this usability goals user interface plays a major role because that
is where the end- user interact with your application/system. This week we are
going to focus on different interaction types in the user interface.
There are four different
interaction types, namely
- Instructing
- Issuing commands and selecting
options
- Conversing
- Interacting by as if having a
conversation
- Manipulating
- Interacting with objects by
manipulating them
- Exploring
- Moving through a virtual
environment or a physical space
1. Interaction Type:
Manipulating
Manipulation
type of interface allows user to manipulate objects presented to
them, using actions that correspond to manipulation of physical objects.
An example of manipulation is re sizing a graphical shape, such
as a rectangle, by dragging its corners or edges with a mouse, dragging,
selecting, opening, closing and zooming actions on virtual objects. By which
users will get a feel like doing the activities with their hand themselves.
Also having real-world metaphors for objects and actions can make it
easier for a user to learn and use an interface and incremental feedback
allows a user to make fewer errors and complete tasks in less time, because
they can see the results of an action before completing the action, thus
evaluating the output and compensating for mistakes.
But it
has few drawbacks ,like few tasks and actions can’t be performed directly(spell
check), sometimes moving a mouse around the screen can be slower than
pressing function keys to do the same actions and it won’t be suitable for
small screens.
Example
Application: IKEA Catalogue (Android mobile application)
IKEA
Catalogue is an
augmented reality mobile app that projects an item into a real-time photograph
image of the user's room. The augmented reality app also provides an indication
of the scale of IKEA objects in relation to the user's living environment.
Let’s see the features available in this app.
Place furniture in your room:
Users
can drag and drop furniture into their living room and visualize how the room
looks after they placed that furniture. They can also zoom in and Zoom out the
furniture size. Since the user can manipulate the furniture and fix it in their
room directly, this app falls under manipulating interaction type.
Scan
and Discover Catalogue:
2. Interaction Type:
Exploring
This conceptual model is
based on the idea of allowing people to explore and browse information,
exploiting their knowledge of how they do this with existing media like books,
magazines, TV, radio, libraries, etc.. It allows people to search, browse and find
different kinds of information.
This involves users
moving through virtual or physical environments. Some examples of virtual
environments include 3D virtual worlds for education, socializing, business,
gaming, etc.. Some examples of physical environments include augmented
reality, location-based services and sensors in the environment.
Exploration is usually
good for open-ended tasks or when goals are unknown or changing.
Example Application:
Google googles (Android mobile application)
Google Googles, a visual
search application for android phones is one among the first efforts to make
use of augmented reality technology on Android. This helps us to do a web
search by taking a photo or scan various objects and google search will try to
identify what it is for us.
This works well for
search book titles, get landmark information, scan business cards to store or
call the contacts, figure out title and artists of a painting, text translation
for unknown languages, etc.. However, visual search technology being in the
booming stage now, we could expect it to even suggest a move in a chess game in
near future.
Below are the pictorial
representations of some benefits of the app.
