it 505 HCI Q2

it is a structured record of facts, concepts and skills that we have acquired. long memory. Semantic memory. overloaded.

it represents our memory of events and experiences in a serial form. long memory. Semantic memory. Episodic memory.

Just as vision begins with light, hearing begins with. vibrations in the air. the auditory nerves. the light.

The ear receives these vibrations and transmits them, to. the auditory nerves. vibrations in the air. the light.

It is the visible part of the ear. The outer ear. the middle ear. the inner ear.

The pinna and auditory canal serve to. amplify some sounds. increase some sounds. reduce some sounds.

Sound waves pass along. middle ear. the auditory canal. the inner ear.

The human ear can hear frequencies from about. 10 Hz to 15 kHz. 30 Hz to 45 kHz. 20 z to 15 kHz.

it performs some filtering of the sounds received. The auditory system. the inner ear. middle ear.

it ignores background noise and concentrate on important information. the inner ear. the middle ear. The auditory system.

it can be used to convey information. perception of colour. Speech sounds. Optical illusions.

the non-speech sounds include. Attention. Speech sounds. Optical illusions.

Using continuous background sounds to convey status information is example for. sound Attention. Brightness. Intensity.

monitoring the progress of a process without the need for visual attention is for example. Brightness. sound attention. Intensity.

a sound associated with an action to confirm that the action has been carried out is. sound attention. sound confirmation. brightness.

associating a sound with deleting a file is example for. Optical illusions. sound confirmation. sound attention.

the limited capacity of sensory and mental processes is feature of. long memory. Sensory memory. short memory.

Information received is quickly passed into a more permanent memory store or overwritten and lost within. long memory. Sensory memory. short memory.

If we did not selectively attend to the stimuli coming into our senses, we would be. long memory. downloaded. overloaded.

using changing sound to indicate where the user is in a system is. sound attention. sound confirmation. sound Navigation.

using sound to support navigation in hypertext is example for. sound attention. sound confirmation. sound Navigation.

The third and last of the senses is used in interaction of computer. Touch. eye. ear.

it is an important means of feedback. Touch. light. Sight.

it is an important part of the task of pressing the button. Feeling buttons depress. vision. light.

the important considerations in the design of interactive systems for movement are. Speed and accuracy. Speed and performance. size and accuracy.

Movement time = a + b log2(distance/size + 1) the constants in this equation are. a and b. a and size. a and distance.

Movement time for mouse depends on. performance and accuracy. distance and size. accuracy and size.

the number of types of memory which is. 5 types. 4 types. 3 types.

A model of the structure of memory starts with. short memory. sensory memory. long memory.

A model of the structure of memory ends with. sensory buffers. long-term memory. working memory.

it is passed from sensory memory into short-term memory by attention. Information. memory. processing.

it is the concentration of the mind on one out of a number of competing stimuli or thoughts. memory. Attention. Information.

sensory memory is. high. slow. quick.
