HUMAN COMPUTER INTERACTIONS(HCI)

Q2. Early implementations of touch and gestural systems often suffered from input errors.
Unfortunately, they also did not provide sufficient user feedback to allow users to associate
input with system output. Answer the following questions about what you might consider when
designing a user interface that uses touch or gesture-based input techniques.

A.Drawing on the HCI core readings list three important considerations that arise for designers
of user interface technologies that rely on touch-based UIs as opposed to mouse-based UIs.

B.What considerations should designers of touch-based UIs take into account when designing
input techniques?

1)To answer this question, describe (or propose) at least two design goals related to
preventing or eliminating input errors in single or multi-touch-based systems.

2) What are the challenges you might face in realizing each goal?

C.What considerations should designers of in-air gesture-based UIs take into account when
designing input techniques?

1)To answer this question, describe (or propose) one design goal related to preventing or
eliminating input errors in gesture-based systems.

2) What are the challenges you might face in realizing the goal?
