Module 2… Talking with computers

2. Making things easier Communication:
1 a the act of imparting, esp. news. b an instance of this. c the information etc. communicated.
2 a means of connecting different places, such as a door, passage, road, or railway.
3 social intercourse (it was difficult to maintain communication in the uproar).
4 (in pl.) the science and practice of transmitting information esp. by electronic or mechanical means.
5 (in pl.) Mil. the means of transport between a base and the front.
6 a paper read to a learned society.

3. Making things easier human–technology communication
communication between people and ICT systems
explores the vital role of the human interface in the success of ICT systems
some of the most basic issues in human–technology communication,
an overview of how the thinking in HTC has evolved in the past two decades
some of the changes in the modes and devices of human–technology interaction

4. ICT everywhere ATM—for money Credit cards Video recording
If we have to know details of how everything actually works we will not be able to use technology
Human interface may prevent access to ICT of people who have different abilities

5. Basic design issues Usability Efficiency Ease of use Accessibility
Should be simple and easy to use
Accessibility

6. Basic design issues Usability
ISO defined the term usability as the ‘effectiveness, efficiency and satisfaction with which a specified set of users can achieve a specified set of tasks in a particular environment’.
usability has become an important concept not only where an end product is concerned, but also to the whole design process

7. Integrating knowledge, ideas and experiences
user interface, originally known as the man–machine interface (MMI),
during the technology explosion in the 1970s.
if they could somehow improve the physical appearance of the user interface, they would have better chances of commercial success.
User-friendly

8. Integrating knowledge, ideas and experiences
HCI,
set of processes, dialogues and actions through which a human user employs and interacts with a computer’ (Baecker and Buxton, 1987, p.40).
‘human–computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of the major phenomena surrounding them’ (ACM SIGGHI, 1992, p.6).

9. Integrating knowledge, ideas and experiences
Human–Computer Communication (HCC)
Human–Technology Interaction (HTI)
Person–Computer Communication (PCC).
Human–Technology Communication (HTC)
Technology as a whole and not just the computer
The field is common to computer scientists and engineers

10. HTC

11. The changing face of technology
Input devices—keyboard and mouse, microphone device, foot mouse, eye movement typing
Line interface
Form-based interface
GUI

12. Speech based interfacing
Speech-based interfacing is becoming increasingly more common
speaking feels more natural than typing on a keyboard,
However, it involve a number of very complex processes that can be considerably difficult to get machines to emulate.
business-like considerations such as productivity
to more social-minded worries such as accessibility by impaired users. Application areas (current and potential) are also various.

13. Making things better Limitation for speech based system
People pronounce differently– it is not robust
Other modes of interacting with machines are considered
It can be a complimentary way of interfacing with technology
Multimodal architecture– more than one way of interfacing
It may be inappropriate to speak like in office
May be confidential information
May cause fatigue

14. Virtual reality

15. Article 1: A brief history of human computer interaction technology
The industry is driven by academic research
The article talks and give dates to how the academia's have developed the technologies we use today

16. Article 2: Taming recognition errors with a multimodal interface
How multimodal interfaces are better
Recognition errors
