The document suggests ideas for using sound properties effectively in an interface. It discusses how sound can convey substantial information but is rarely used to its full potential in interfaces, usually only for warnings. However, the ear can differentiate subtle sound changes and recognize familiar sounds without focusing attention. This means sound could be used more in interfaces to provide information on the system state. Some ideas presented are using speech sounds to convey information, which is useful for visually impaired users or when attention needs to be divided. Non-speech sounds could also be used for getting attention, conveying status information continuously, or providing confirmation.

ACTIVITY

Create an essay and suggest ideas for an interface which uses the properties of sound effectively. You might approach
this exercise by considering how sound could be added to an application with which you are familiar. Use your
imagination. (100 words)

As we know, sound can convey a remarkable amount of information. It is rarely used to its potential in interface
design, usually being confined to warning sounds. However, the ear can differentiate quite subtle sound changes and
can recognize familiar sounds without concentrating attention on the sound source. This suggests that sound could be
used more extensively in interface design, to convey information about the system state. The next suggested ideas for
an interface is Worked exercise which uses the properties of sound effectively. This is a good subject for a literature
survey. Speech sounds can obviously be used to convey information. This is useful not only for the visually impaired but
also for any application where the user’s attention has to be divided. Just for example, in power plant control, flight
control and many more not only this.
If there is speech sounds, there is also we called the Non-speech sounds. It’s uses includes the attention, for
example is to attract the user’s attention to a critical situation or to the end of a process; the status information, which is
continuous background sounds can also be used to convey information; also include the confirmation, and navigation.

ASSESSMENT
1. What is the 5 major of senses? And explain each and make a situation that are uses a sense.
Answer:
SIGHT – It is a power seeing. Like you wanted to see an object, our eyes plays a vital role.
HEARING- is used to listen sounds. Just like listening musics.
TOUCH – provides us with vital information about our environment, lifting an object. Provide us with
feedbacks. Like touching hot or a cold water. Though touching can easily identify.
SMELL, TASTE – This two major senses is still unused in computing. Though it plays a role in a human
body.

ANSWER:
SHORT TERM MEMORY

10. Define what is HCI?


ANSWER:
HCI means Human-computer interaction. It is a multidisciplinary field of study focusing on the design of
computer technology and, in particular, the interaction between humans(the users) and computers. While initially
concerned with the computers, HCI has since expanded to cover almost all forms of information technology
