This is one of those minor annoyances that shouldn&#8217;t bother anyone but it just seems weird that all the amazing technological advances in television (high-definition picture, thousands of channels to choose from) should come at the cost of the &#8220;crispness&#8221; in performance that I remember from the old analog broadcasts.<\/p>\n<p>The lack of responsiveness really becomes noticeable during casual browsing. The two- or three-second pause between channel clicks appears to be much longer than the amount of time the average human needs to evaluate the onscreen content. This sets you up for a lot of waiting and really has a negative impact on the user&#8217;s experience. If you have cable, you can use the guide feature, of course, but it just doesn&#8217;t provide the same satisfaction as a good, old-fashioned, rapid-fire channel surf.<\/p>\n<p>In a recent\u00a0<a href=\"http:\/\/www.useit.com\/alertbox\/response-times.html\" target=\"_blank\" rel=\"nofollow noopener\">article<\/a>, Jacob\u00a0Nielsen revisited the topic of website response times and noted that delays of even a few seconds can contribute to an unpleasant user experience. He highlights three basic response speeds and how they relate to the human attention span:<\/p>\n<p><strong> <\/strong><\/p>\n<p><strong> <\/strong><\/p>\n<ul>\n<li><span style=\"font-weight: normal;\"><strong>0.1 seconds<\/strong> provides a user with the fee<\/span><span style=\"font-weight: normal;\">ling of an\u00a0instantaneous response \u2014 a level of responsiveness that is essential to supporting the feeling of\u00a0direct manipulation.<\/span><\/li>\n<li><span style=\"font-weight: normal;\"><strong>1 second<\/strong> keeps the user&#8217;s flow of thoug<\/span><span style=\"font-weight: normal;\">ht\u00a0seamless and still allows them to feel in control<\/span><span style=\"font-weight: normal;\">. This degree of responsiveness is needed for good navigation.<\/span><\/li>\n<li><span style=\"font-weight: normal;\"><strong>10 seconds<\/strong> keeps the user&#8217;<\/span><span style=\"font-weight: normal;\">s\u00a0attention but they are starting to feel that they are <\/span><span style=\"font-weight: normal;\">at the mercy of the computer and wish it was faster. After 10 seconds, their mind starts to wander.<\/span><\/li>\n<\/ul>\n<p>These limits would apply equally well to an established technology like television.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>As I was flipping through the stations on the TV the other day, I became particularly aware of the slight delay between the time I pressed the button on the remote and&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[18,106,12,108],"class_list":["post-121","post","type-post","status-publish","format-standard","hentry","category-design","tag-channel-surfing","tag-tv-remote","tag-usability","tag-user-experience"],"jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/ideasillustrated.com\/blog\/wp-json\/wp\/v2\/posts\/121","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ideasillustrated.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ideasillustrated.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ideasillustrated.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/ideasillustrated.com\/blog\/wp-json\/wp\/v2\/comments?post=121"}],"version-history":[{"count":1,"href":"https:\/\/ideasillustrated.com\/blog\/wp-json\/wp\/v2\/posts\/121\/revisions"}],"predecessor-version":[{"id":2168,"href":"https:\/\/ideasillustrated.com\/blog\/wp-json\/wp\/v2\/posts\/121\/revisions\/2168"}],"wp:attachment":[{"href":"https:\/\/ideasillustrated.com\/blog\/wp-json\/wp\/v2\/media?parent=121"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ideasillustrated.com\/blog\/wp-json\/wp\/v2\/categories?post=121"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ideasillustrated.com\/blog\/wp-json\/wp\/v2\/tags?post=121"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
