Introduction

웹 어플에서 새로운 정보를 사용자에게 알려줄 경우, 사용자의 주목을 끌어야함

•팝업이 가장 많이 쓰이는데, 사용자의 주목 끄는데 효과적이지만, 결국엔 짜증나서 무시하게 됨

•여러가지의 attention grabber presentation 들 중 어떤 것이 가장 효과적이고 매력있는 visual

techniques 인지 알아 볼 필요가 있음

Definition

Attention Grabber (AG)

• Any user interfce element that tries to get the user to attend to it

•NOT “notification” - includes unrelated visual elements like advertisement

EXPERIMENT DESIGN

Page 13: Getting User's Attention in Web Apps in Likable, Minimally Annoying Ways

Experiment Design

Goal: Quantify varying visual presentations of AGs

•Independent Variable = AG style

•Dependent measures = Participant’s Reaction Time, Recall of AG content, Responses to survey questions

•Between subject design - each participant only seeing 1 AG during their session

Independent Variable: Attention Grabbers

Interruption, Reaction, Comprehension

Interruption Reaction

Comprehension

•Low interruption, reaction, and comprehension

•High Interruption

•High comprehension

•High reaction

•High interruption and reaction

•High interruption and comprehension

•High comprehension and reaction

Page 15: Getting User's Attention in Web Apps in Likable, Minimally Annoying Ways

Indepedent Variable: Attention Grabbers

High

•Interruption - fast pulse

•ex. color pulse fast, glow pulse fast, message pulse fast

•Comprehension - marquee

•ex. scrolling marquee, fading marquee

•Reaction - g chat pop up

SNU UX _ Lab Meeting

•Interruption + Reaction - pop up

•Interruption + Comprehension - slow pulse

•Comprehension + Reaction - message badge

Dependent variables: Perforance, Reaction Time, Survey, and Recall

Experiment Context - Set Game

Set Game 의 환경으로 한 이유?

•Between subject design - each participant only seeing 1 AG during their session

SNU UX _ Lab Meeting

•(1) Engaging 하며, 집중력을 요구하기 때문에

•(2) 성과에 따른 보상을 지급 할수 있어서

•(3) (하기) 쉽고, 리쿠르팅하기도 쉬워서

•I noticed a (AG)

•As soon as the (AG) appeared, I saw it immediately

•The (AG) grabbed my attention

Component Analysis: Likability

•The (AG) was asethetically pleasing

•I liked the (AG)

•I wish that other sites would use a smiliar (AG) when they needed to get my attention

Likability by attention grabber type

Annoyance by Attention grabber type

•Likable: Message icon with Badge —> glow pulse

•Least Likabe: pop up —> marquee

Page 29: Getting User's Attention in Web Apps in Likable, Minimally Annoying Ways

Recall

SNU UX _ Lab Meeting

Recall: whether people remembered the icon

•의외로... 소수의 사람들이 맞췄음 (최고로 33%...)

•많은 사람들이 메세지 아이콘을 기억 못함

•percent of participants who remembered the icon correctly

Design

SNU UX _ Lab Meeting

DR 1. For immediate attention, use pulsing shadows

•pulsing shadows (glow pulse slow + fast)

•pop-up 이랑 비슷하게 noticeable 하지만, more likable + less annoying

DR 2. For less- critical info, use an icon with a badge

•message boy with a badge = most likable/ least annoying 하지만 noticeability 가 낮음

DR 3. If something must pop up, make sure it integrates well with the page

•pop-up - quick reactions but significantly annoying

•if integrated within the page, it is perceived as part of the page

Summary

배경

SNU UX _ Lab Meeting

목표

방법

결과

키워드 #User Interface Design #Attention #Alerts #Notifications

1) glowing shadow UI element가 가장 호감을 얻을수 있고, 효과적으로 사용자의 주목을 끔 2) less- critical 한 정보를 제공 할 경우, badge 가 있는 아이콘들이 좋다

1505 명의 사용자들의 reaction time, noticeability, annoyance, likability, recall 을 알아봄으로,

15개의 attention grabbers 들 중 어떤 테크닉이 가장 효과적으로 1) users’ attention 2) likability 3) recall

of information을 획득할수 있는지 비교

사용자들의 “attention”을 끌기위해, pop- up 이 많이 사용됨.

그러나 popup은 사용자의 이목을 끌지 못하고 불쾌감을 유발하여 오히려 역효과를 냄

Attention grabbers presentation에 대해서 살펴봄

이 논문에서는 웹페이지에서 어떤 “효과적이고, ” “매력적인” 디자인 가이드라인이 사용자의 이목을 끄는지 알아봄

“언제” “어떻게” 새로운 정보를 시각적으로 보여주는게 좋은지에 대한 선행 연구가 있음

Page 32: Getting User's Attention in Web Apps in Likable, Minimally Annoying Ways

?•프로포절 주제 | 뉴스 카테고리 재배치의 뉴스 읽기 연구를 더 구체화 하는데 도움 될 것같음

•Attention Grab을 하기위해, 각기 다른 UI elements와 배치 위치 (replacement)를 통해, 어떤 조합이 사용자들에게

notieable, annoying, likable 한지 알아본것이 흥미로움

•실험을 정교하게 설계함 --> 실제 실험을 진행 할때 참고해볼 수 있을것임

SNU UX _ Lab Meeting

+

-

•독립 변수와 종속 변수에 대한 관계를 명확하게 명시

•논문 쓸때, 어떻게 정교하게 실험을 설계 할지 참고 할 수 있을것

•survey - based measure로만 하고, 사후 인터뷰를 하지 않음

•web application 뿐만 아니라 다른 플랫폼 (모바일)에서도 적용하면 좋았을것 같음

나의 후기...
