Such basic features include colors, closure, line ends, contrast, tilt, curvature and size. These simple features are extracted from the visual display in the preattentive system and later joined in the focused attention system into coherent objects. Preattentive processing is done quickly, effortlessly and in parallel without any attention being focused on the display.|[Treisman, 1985, Treisman, 1986]}}<br /> <br /> {{Quotation|Typically, tasks that can be performed on large multi-element displays in less than 200 to 250 milliseconds (msec) are considered preattentive.|[Healey, 2005]}}<br /> <br /> Taking advantage of preattentive processing in [[information visualization]] can greatly improve intuitiveness of representations yielding in a faster and more natural way of acquiring information.<br /> <br /> {{Quotation|Visualization is so effective and useful because it utilizes one of the channels to our brain that have the highest bandwidths: our eyes. But even this channel can be used more or less efficiently. One special property of our visual system is preattentive processing.|[Kosara, 2002]}} <br /> <br /> {{Quotation|One very interesting result of vision research over the past 20 years has been the discovery of a limited set of visual properties that are processed preattentively (i.e. without the need for focused attention). Typically, tasks that can be performed on large multi-element displays in 200 milliseconds or less are considered preattentive.This is because eye movements take at least 200 milliseconds to initiate. Any perception that is possible within this time frame involves only the information available in a single glimpse. Random placement of the elements in the displays ensures that attention cannot be prefocused on any particular location. Observers report that these tasks can be completed with very little effort.|[Healey et al., 1996]}}<br /> <br /> == Preattentive Features==<br /> <br /> [[Image:Features.jpg]]<br /> <br /> A partial list of preattentive visual features, together with references to research that showed they were preattentive.[Chipman, 1996],<br /> <br /> ----<br /> <br /> [[Image:Preattantive_1.jpg]] <br /> <br /> Detecting the Red Object preattentively.[Healey et al., 1996] One visual variable and very easy to find it. <br /> <br /> <br /> <br /> <br /> <br /> <br /> [[Image:Preattantive_2.jpg]]<br /> <br /> Detecting the Circle preattentively.[Chipman, 1996] It is more difficult but still preantentiv.<br /> <br /> <br /> <br /> <br /> <br /> [[Image:Preattentive_4.JPG]]<br /> <br /> Examples of two target detection tasks: (a) target can be detected preattentively because it possess the feature “filled”; (b) target cannot be detected preattentively because it has no visual feature that is unique from its distractors.[Healey et al., 1996]<br /> <br /> <br /> <br /> <br /> <br /> [[Image:Preattentive_3.JPG]]<br /> <br /> Region segregation by form and hue: (a) hue boundary is identified preattentively, even though form varies randomly in the two regions; (b) random hue variations interfere with the identification of a region boundary based on form.[Healey et al., 1996]<br /> <br /> ==Conclusion==<br /> Any visual processing of that item prior to the act of selection can be called “preattentive”.[Wolfe, Treisma, 2003]<br /> <br /> Preattentive processing can help to rapidly draw the focus of attention to a target with a unique visual feature (i.e., little or no searching is required in the preattentive case).

Such basic features include colors, closure, line ends, contrast, tilt, curvature and size. These simple features are extracted from the visual display in the preattentive system and later joined in the focused attention system into coherent objects. Preattentive processing is done quickly, effortlessly and in parallel without any attention being focused on the display.|[Treisman, 1985, Treisman, 1986]}}<br /> <br /> {{Quotation|Typically, tasks that can be performed on large multi-element displays in less than 200 to 250 milliseconds (msec) are considered preattentive.|[Healey, 2005]}}<br /> <br /> Taking advantage of preattentive processing in [[information visualization]] can greatly improve intuitiveness of representations yielding in a faster and more natural way of acquiring information.<br /> <br /> {{Quotation|Visualization is so effective and useful because it utilizes one of the channels to our brain that have the highest bandwidths: our eyes. But even this channel can be used more or less efficiently. One special property of our visual system is preattentive processing.|[Kosara, 2002]}} <br /> <br /> {{Quotation|One very interesting result of vision research over the past 20 years has been the discovery of a limited set of visual properties that are processed preattentively (i.e. without the need for focused attention). Typically, tasks that can be performed on large multi-element displays in 200 milliseconds or less are considered preattentive.This is because eye movements take at least 200 milliseconds to initiate. Any perception that is possible within this time frame involves only the information available in a single glimpse. Random placement of the elements in the displays ensures that attention cannot be prefocused on any particular location. Observers report that these tasks can be completed with very little effort.|[Healey et al., 1996]}}<br /> <br /> == Preattentive Features==<br /> <br /> [[Image:Features.jpg]]<br /> <br /> A partial list of preattentive visual features, together with references to research that showed they were preattentive.[Chipman, 1996],<br /> <br /> ----<br /> <br /> [[Image:Preattantive_1.jpg]] <br /> <br /> Detecting the Red Object preattentively.[Healey et al., 1996] One visual variable and very easy to find it. <br /> <br /> <br /> <br /> <br /> <br /> <br /> [[Image:Preattantive_2.jpg]]<br /> <br /> Detecting the Circle preattentively.[Chipman, 1996] It is more difficult but still preantentiv.<br /> <br /> <br /> <br /> <br /> <br /> [[Image:Preattentive_4.JPG]]<br /> <br /> Examples of two target detection tasks: (a) target can be detected preattentively because it possess the feature “filled”; (b) target cannot be detected preattentively because it has no visual feature that is unique from its distractors.[Healey et al., 1996]<br /> <br /> <br /> <br /> <br /> <br /> [[Image:Preattentive_3.JPG]]<br /> <br /> Region segregation by form and hue: (a) hue boundary is identified preattentively, even though form varies randomly in the two regions; (b) random hue variations interfere with the identification of a region boundary based on form.[Healey et al., 1996]<br /> <br /> ==Conclusion==<br /> Any visual processing of that item prior to the act of selection can be called “preattentive”.[Wolfe, Treisma, 2003]<br /> <br /> Preattentive processing can help to rapidly draw the focus of attention to a target with a unique visual feature (i.e., little or no searching is required in the preattentive case).

{{Quotation|'''Preattentive processing''' of visual information is performed automatically on the entire visual field detecting basic features of objects in the display. Such basic features include colors, closure, line ends, contrast, tilt, curvature and size. These simple features are extracted from the visual display in the preattentive system and later joined in the focused attention system into coherent objects. Preattentive processing is done quickly, effortlessly and in parallel without any attention being focused on the display.|[Treisman, 1985, Treisman, 1986]}}<br /> <br /> {{Quotation|Typically, tasks that can be performed on large multi-element displays in less than 200 to 250 milliseconds (msec) are considered preattentive.|[Healey, 2005]}}<br /> <br /> Taking advantage of preattentive processing in [[information visualization]] can greatly improve intuitiveness of representations yielding in a faster and more natural way of acquiring information.<br /> <br /> {{Quotation|Visualization is so effective and useful because it utilizes one of the channels to our brain that have the highest bandwidths: our eyes. But even this channel can be used more or less efficiently. One special property of our visual system is preattentive processing.|[Kosara, 2002]}} <br /> <br /> {{Quotation|One very interesting result of vision research over the past 20 years has been the discovery of a limited set of visual properties that are processed preattentively (i.e. without the need for focused attention). Typically, tasks that can be performed on large multi-element displays in 200 milliseconds or less are considered preattentive.This is because eye movements take at least 200 milliseconds to initiate. Any perception that is possible within this time frame involves only the information available in a single glimpse. Random placement of the elements in the displays ensures that attention cannot be prefocused on any particular location. Observers report that these tasks can be completed with very little effort.|[Healey et al., 1996]}}<br /> <br /> == Preattentive Features==<br /> <br /> [[Image:Features.jpg]]<br /> <br /> A partial list of preattentive visual features, together with references to research that showed they were preattentive.[Chipman, 1996],<br /> <br /> ----<br /> <br /> [[Image:Preattantive_1.jpg]] <br /> <br /> Detecting the Red Object preattentively.[Healey et al., 1996] One visual variable and very easy to find it. <br /> <br /> <br /> <br /> <br /> <br /> <br /> [[Image:Preattantive_2.jpg]]<br /> <br /> Detecting the Circle preattentively.[Chipman, 1996] It is more difficult but still preantentiv.<br /> <br /> <br /> <br /> <br /> <br /> [[Image:Preattentive_4.JPG]]<br /> <br /> Examples of two target detection tasks: (a) target can be detected preattentively because it possess the feature “filled”; (b) target cannot be detected preattentively because it has no visual feature that is unique from its distractors.[Healey et al., 1996]<br /> <br /> <br /> <br /> <br /> <br /> [[Image:Preattentive_3.JPG]]<br /> <br /> Region segregation by form and hue: (a) hue boundary is identified preattentively, even though form varies randomly in the two regions; (b) random hue variations interfere with the identification of a region boundary based on form.[Healey et al., 1996]<br /> <br /> ==Conclusion==<br /> Any visual processing of that item prior to the act of selection can be called “preattentive”.[Wolfe, Treisma, 2003]<br /> <br /> Preattentive processing can help to rapidly draw the focus of attention to a target with a unique visual feature (i.e., little or no searching is required in the preattentive case).
