Animated virtual agents to cue user attention: comparison of static and dynamic deictic cues on gaze and touch responses

This paper describes an experiment developed to study the performance of virtual agent animated cues within digital interfaces. Increasingly, agents are used in virtual environments as part of the branding process and to guide user interaction. However, the level of agent detail required to establish and enhance efficient allocation of attention remains unclear. Although complex agent motion is now possible, it is costly to implement and so should only be routinely implemented if a clear benefit can be shown. Pevious methods of assessing the effect of gaze-cueing as a solution to scene complexity have relied principally on two-dimensional static scenes and manual peripheral inputs. Two experiments were run to address the question of agent cues on human-computer interfaces. Both experiments measured the efficiency of agent cues analyzing participant responses either by gaze or by touch respectively. In the first experiment, an eye-movement recorder was used to directly assess the immediate overt allocation of attention by capturing the participant’s eyefixations following presentation of a cueing stimulus. We found that a fully animated agent could speed up user interaction with the interface. When user attention was directed using a fully animated agent cue, users responded 35% faster when compared with stepped 2-image agent cues, and 42% faster when compared with a static 1-image cue. The second experiment recorded participant responses on a touch screen using same agent cues. Analysis of touch inputs confirmed the results of gaze-experiment, where fully animated agent made shortest time response with a slight decrease on the time difference comparisons. Responses to fully animated agent were 17% and 20% faster when compared with 2-image and 1-image cue severally. These results inform techniques aimed at engaging users’ attention in complex scenes such as computer games and digital transactions within public or social interaction contexts by demonstrating the benefits of dynamic gaze and head cueing directly on the users’ eye movements and touch responses

A study of effective Web advertising design to maximize click-through and brand awareness

Technological developments provide important opportunities to advertisers and marketers can now reach large masses of people more efficiently through a variety of media. Web advertising has become widely known as an efficient and effective communication tool, and it is fast becoming the medium for mass communication in the advertising industry. Despite the Web\u27s capability to be a potentially powerful medium for advertising, few research studies have been conducted regarding the effectiveness of visual communication in Web advertising compared to other advertising media. Generally, there are two main purposes for Web advertising: (a) build a brand, or (b) conduct direct marketing. Brand advertising associates the positive qualities or emotions with a company\u27s product or service, while direct marketing attempts to stimulate a direct sale. Visual design elements need to be formulated that specify exactly which advertising objectives are being targeted. The primary objective of this study was to develop a method to analyze the components of Web design elements and communication styles in banner advertisements to enable Web advertising designers to maximize the effectiveness of Web advertising. The research found that click-through and brand-reinforcement design elements have both a comparative and inverse relationship. The findings demonstrate that a higher level of click-through ad design is associated with lower brand-reinforced ad design. Similarly, a higher level of brand-reinforced design is associated with lower click-through. The researcher presented a typology to be used as guidelines to determine the effectiveness of Web advertising design to maximize click-through and brand-reinforcement. Most studies on Web advertising have been conducted primarily on click-through behavior. Since many demands are based on the importance of brand-reinforcement in Web advertising, this study does provide some groundwork in this field. Therefore, further study in this area is strongly recommended

The Meaning of Movement: Using Motion Design to Enrich Words for Deaf and Hard of Hearing Children

This thesis aims to address challenging areas of vocabulary for deaf and hard of hearing children by developing an open resource for students, parents, teachers, and content creators that utilizes motion to enhance written words for deaf and hard of hearing children. This research seeks to study the means of nonverbal communication such as body language expression and paralinguistic prosody (i.e., tone, intonation, volume, and pitch) qualities within the framework of graphic design through motion design. Body movement and expression are essential during face-to-face communication, but written language lacks such context clues. Additionally, the hard of hearing may not fully detect prosody within their range of hearing. This lack of information gathered through body language and paralanguage can be replicated with animated movement, which adds greater context to otherwise static text, enhancing insight into the meaning or use of a word. Seeing how a word in written form correlates with enhanced meaning through movement provides greater understanding and retention. This enhancement promotes improved communication in the world through graphic design. Motion design, specifically kinetic typography, offers a promising tool to help aid with language learning for continued exploration and development

Kindertivity: Usability and Communicability Strategies for Interactive Surfaces and Pre-Kindergarten Children

Tesis por compendio[ES] La tecnología multi-táctil se ha convertido en una de las más emergentes tras experimentar un enorme crecimiento desde sus pasos iniciales en los años ochenta hasta su amplia aceptación y uso en la actualidad. Por una parte, la tecnología multi-táctil se basa en el estilo de interacción de manipulación directa el cual proporciona a los usuarios la ventaja de ver los objetos y las acciones de interés, sustituir comandos escritos por acciones de señalado y, además, permite la realización de acciones rápidas, reversibles e incrementales evitando el uso de instrucciones complejas. Por otra parte, diversos trabajos han evaluado las virtudes derivadas de utilizar conjuntamente la manipulación directa con el toque directo mostrando que es posible evitar los problemas inherentes a otras técnicas de interacción como el ratón y el teclado. Por lo tanto, aprovechando la interacción natural e intuitiva proporcionada por la tecnología multi-táctil, ésta parece una forma ideal para dar soporte a la creación de escenarios educativos dirigidos a niños en edad preescolar. Sin embargo, a pesar de la existencia de diversos estudios que evalúan la idoneidad de utilizar el estilo de interacción de manipulación directa, existe una falta de trabajos abordando el uso dispositivos basados en superficies táctiles con niños de una temprana edad. Asimismo, en la actualidad existe una creciente tendencia a diseñar aplicaciones educativas y lúdicas dirigidas a niños en edad preescolar utilizando dispositivos multi-táctiles como los teléfonos inteligentes o las tabletas. Además, diversos informes señalan que los niños son usuarios frecuentes de este tipo de dispositivos y los utilizan incluso antes de ser capaces de hablar. Sin embargo, a pesar de este crecimiento en el uso de la tecnología multi-táctil y su aparente idoneidad para ser utilizado en el desarrollo de aplicaciones educativas para niños en edad preescolar, no existen unas interacciones universales y estandarizadas para preescolares a la hora de utilizar dispositivos táctiles ya que habitualmente sólo se utilizan dos gestos básicos (básicamente, el toque con un dedo para seleccionar y el arrastre con un dedo para el movimiento). Por lo tanto, existe una clara necesidad de llevar a cabo estudios empíricos para contribuir y avanzar en el diseño de aplicaciones que den un soporte adecuado y encaje con las habilidades de los niños en su temprano desarrollo. Por tanto, esta tesis propone, diseña y evalúa diversas estrategias de usabilidad y comunicabilidad adaptadas a los niños en edad preescolar para establecer la base para el diseño y desarrollo de futuras aplicaciones basadas en dispositivos táctiles dirigidas a preescolares. Estas estrategias llevarán a la adecuada definición de guías de diseño que permitirán a los niños aprovechar al máximo la tecnología multi-táctil, harán posible el desarrollo de nuevas y atractivas aplicaciones y, eventualmente, también podrán ayudar al desarrollo cognitivo y motor de los niños.[CA] La tecnologia multi-tàctil s'ha convertit en una de les més emergents després d'experimentar un enorme creixement des dels seus passos inicials als anys vuitanta fins l'actualitat on es àmpliament acceptada i utilitzada. D'una banda, la tecnologia multi-tàctil es basa en l'estil d'interacció de manipulació directa, el qual proporciona als usuaris l'avantatge de veure els objectes i les accions d'interès, substituir comandos escrits per accions d'assenyalament i, a més, permet la realització d'accions, ràpides, reversibles i incrementals evitant l'ús d'instruccions complexes. D'altra banda, diversos treballs han avaluat les virtuts derivades d'utilitzar conjuntament la manipulació directa amb el toc directe mostrant que és possible evitar els problemes inherents a altres tècniques d'interacció com el ratolí i el teclat. Per tant, aprofitant la interacció natural i intuïtiva proporcionada per la tecnologia multi-tàctil, aquesta sembla una forma ideal per donar suport a la creació d'escenaris educatius per a xiquets en edat preescolar. No obstant això, malgrat l'existència de diversos estudis que avaluen la idoneïtat d'utilitzar l'estil d'interacció de manipulació directa, existeix una manca de treballs abordant l'ús de dispositius basats en superfícies tàctils amb xiquets d'edat primerenca. Així mateix, en l'actualitat existeix una creixent tendència a dissenyar aplicacions educatives i lúdiques dirigides a xiquets en edat preescolar utilitzant dispositius tàctils com els telèfons intel¿ligents o les tauletes. A més, diversos informes assenyalen que els xiquets són usuaris freqüents d'aquests tipus de dispositius i els utilitzen fins i tot abans de ser capaços de parlar. Malgrat aquest creixement en l'ús de la tecnologia multi-tàctil i la seua aparent idoneïtat per a ser utilitzada en el desenvolupament d'aplicacions educatives per a xiquets en edat preescolar, no existeixen unes interaccions universals i estandarditzades per a preescolars a l'hora d'utilitzar dispositius tàctils ja que habitualment només s'utilitzen dos gestos bàsics (bàsicament, el toc amb un dit per a seleccionar i l'arrossegament amb un dit per al moviment). Per tant, hi ha una clara necessitat de dur a terme estudis empírics per a contribuir i avançar en el disseny d'aplicacions que donen un suport adequat i s'ajusten amb les habilitats dels xiquets en el seu primerenc desenvolupament. Per tant, la tesi proposa, dissenya i avalua diverses estratègies de usabilitat i comunicabilitat adaptades als xiquets en edat preescolar per tal d'establir la base per al disseny i desenvolupament de futures aplicacions basades en dispositius tàctils dirigides a preescolars. Aquestes estratègies portaran a l'adequada definició de guies de disseny que permetran als xiquets aprofitar al màxim la tecnologia multi-tàctil, faran possible el desenvolupament de noves i atractives aplicacions i, eventualment, podran també ajudar al desenvolupament cognitiu i motor dels xiquets.[EN] Multi-touch technology has become one of the most emergent technologies and has had an enormous growth since its initial steps in the eighties to be widespread accepted and used in the present. On the one hand, multi-touch technology relies on the direct manipulation interaction style which gives users the advantage to view the objects and actions of interest, replace typed commands by pointing actions and to perform rapid, reversible and incremental actions avoiding using complex instructions. On the other hand, several works have evaluated the virtues when joining direct manipulation with direct-touching showing that it solves the problems inherent in other interaction devices, such as those involving mouse or keyboard. Hence, taking advantage of the intuitive and natural interaction provided by multi-touch technology it seems an ideal way to support educational scenarios targeted to kindergarten children. Although several works have assessed the suitability of using the direct manipulation style with children, there is a lack of works addressing the use of touchscreen devices by this specific type of users. Moreover, there is a growing trend of designing educational and playful applications targeted to kindergarten children based on touchscreen devices such as smartphones and tablets. In addition, several reports point out that children use touchscreen devices even before they are able to speak and they are frequent users of devices such as smartphones and tablets. However, despite this growth in the use of multi-touch technology by children and its apparent suitability to be used to develop applications targeted to young children, there is a lack of standardized and universally accepted interactions for young children when using touchscreen devices since only two basic gestures are commonly used (basically, consisting of only one-finger touch for selection and one-finger drag for movement). Hence, there is a need of carrying out empirical studies to help and advance in the design of applications that adequately support and fit with children's development and skills. Therefore, this thesis proposes, designs and evaluates several usability and communicability strategies tailored to children in their early development stage to establish the design and development of future applications targeted to kindergarten children. These strategies will lead to define appropriate design strategies that enable infants to take full advantage of multi-touch technology, would make it possible to develop attractive new applications and, eventually, could also aid children's cognitive and motor development.Nácher Soler, VE.

Brand Identification and Advertisement Appreciation of Online, Print, and TV Advertisements

This study explores the effects of media type (including online, print, and TV), advertisement shape, and online animation level on advertising responses such as recall, recognition, attitude, and purchase intent. The study examined a set of 1636 surveys, each collecting consumer responses to an individual advertisement, conducted by the consumer research and consulting firm OTX Research. The findings showed that underlying the considered measures were two factors, brand identification and advertisement appreciation, and that media type and advertisement shape produced significant differences in these factors. While online advertisements had the highest brand identification, TV advertisements had the highest advertisement appreciation. Additionally, the three advertisement characteristics were able to effectively discriminate between high and low levels of these factors. The findings allow for intuitive explanations of how consumer engagement and sought experiences may be producing the comparative effects of online, print and TV advertisements

Passive visual behavior modifiers and consumer psychophysiology online.

Through an examination of the electroencephalography (EEG) data collected from 27 university students, this study examined the efficacy of three known passive visual behavior modifiers -- color, layout, and motion -- in an e-commerce environment. These three variables have significant scholarly support in the context of traditional media, but their effect online is still largely unsubstantiated. Using EEG readings taken from regions of interest Fp1 and Fp2, the researcher attempted to measure and compare sustained evoked response upon exposure to six fictitious e-commerce web pages, each exhibiting a different passive visual behavior modifier. It was hypothesized that (H1) a product in a subtle state of motion, (H2) a greater proportion of image to text, and (H3) a color system with a dominant wavelength of approximately 650nm would evoke higher average levels of amplitude (μV) and frequency (Hz) in the ventromedial prefrontal cortex compared to stimuli exhibiting inverse properties: a static product image, a greater proportion of text to image, and a color system with a dominant wavelength of approximately 490nm. The biofeedback measurement was supplemented by a qualitative interview. Participant responses were analyzed for key words, phrases, and trends related to consumer attitude and product preference. While no significant differences were found between the visual stimuli, this study provides insight, limitations, and direction for future psychophysiological research relating to e-commerce.--Abstract
