There is no “best”
conceptual
model
YOUR VIEWS?

3. DM is good for “doing” types of tasks –
e.g designing, drawing, flying, driving
Instructions good for repetitive tasks

4. Interface metaphors
 Interface designed to be similar to a physical entity but
also has it's own properties
 – e.g desktop metaphor, web portals

5. Pros/Cons of interface metaphors
 Helps users understand the underlying conceptual model
 Makes learning of new systems easier
 Cons
 Makes learning of new systems easier
 Any other?

6. Interaction Styles
 Command
 Speech
 Data entry
 Form filling
 Query
 Pen
 Augmented reality
 Gesture ....
 Graphical

7.  What is difference VR and AR?

8. Which interaction style to choose ?
 YOUR VIEWS?
 Need to determine requirements and user
needs
 Take the budget and other constraints into
account
 Also will depend on suitability of technology
for activity being supported

9. Interaction paradigms
 From the desktop to ubiquitous computing (embedded in the environment)
Examples of new paradigms
 Ubiquitous computing
 augmented reality
 Transparent computing ..

Knowledge in the head and in
the world
Travel through a city without being able to describe the route precisely

11.  Information in the world
 Great precision is not required
 Natural constraints are present
 Cultural constraints are present

12. Knowledge and constraints
 Declarative knowledge : knowledge “of” – Stop at red lights
 Screws (clockwise, counterclockwise)
