IT- 505 (HCI) Q1

Experiments have shown for reading that standard font sizes of................. 9 to 12 points. 12 to 14 points. 13 to 15 points.

the line lengths are equally legible which are between. 2.3 and 5.2 inches. 2 and 3 inches. 1 and 4 inches.

The eye moves backwards over the text as well as forwards, in what are known as. Regressions. vibrations. transmits.

visual perception is. perception of colour. the perception of brightness. Optical illusions.

Colour is usually regarded as being made up of three components. hue, intensity and saturation. luminance and illusion. luminance and brightness.

It is a physical characteristic and can be measured using a photometer. Luminance. Brightness. Intensity.

During reading, the eye makes jerky movements called. optical vision. the visual pattern. saccades.

it effects on page symmetry. Optical illusions. visions. the visual pattern.

If the text is complex, there will be more. Transmits. vibrations. regressions.

language processing includes. interface. the visual pattern. operations on phrases or sentences.

Language processing includes. Interface. syntactic and semantic analysis. the visual pattern.

it is removed which is detrimental to reading speed and accuracy. letters of word. the word shape clues. the real words.

it is reflected from objects in the world and their image is focused upside down on the back of the eye. light. Touch. Sight.

it plays a part too in that you will feel the keys moving or the orientation of the mouse, which provides vital feedback about what you have done. Touch. vision. light.

it does not play a direct role in sending information although they may be used to receive information. Sight and hearing. Touch. light.

it is in fact a subjective reaction to levels of light. Optical illusions. Contrast. Brightness.

it is determined by the spectral wavelength of the light. saturation. intensity. Hue.

it is the brightness of the colour, and saturation is the amount of whiteness in the colour. Intensity. Hue. saturation.

it is dependent on the amount of light falling on the object's surface and its reflective properties. Brightness. The luminance of an object. Intensity.

it highlights the differences between the way things are and the way we perceive them. graphic design. Optical illusions. brightness.

it is a function of the luminance of an object and the luminance of its background. Optical illusions. brightness. Contrast.

it is a mechanism for receiving light and transforming it into electrical energy. the finger. The eye. the ear.

It plays the primary role, through typing or mouse control. eyes. fingers. legs.

information is received and responses given via a number of input and output, itis one of them. haptic channel. memory. processing.

it has a graphical interface, with menus, icons and windows. an application. HCI. vision.

it does not currently play a significant role in HCI. hearing and touch. Taste and smell. sight and hearing.

Adults read approximately. 150 words a minute. 200 words a minute. 250 words a minute.

information is received and responses given via a number of input and output, it is one of them. Memory. auditory channel. Eliminate quotas principle.

Information is received and responses given via a number of input and output, it is one of them. Memory. processing. visual channel.
