Liveboard: a large interactive display supporting group meetings, presentations, and remote collaboration

Este artigo remonta ao ano de 1992 e apresenta uma aplicação que visa dar suporte a reuniões de grupo e apresentações usando um quadro de grandes dimensões interactivo.

Apresenta como dispositivo de entrada uma caneta, é assim limitado na medida em que não existe qualquer aproveitamento do espaço que rodeia o quadro sendo toda a interacção realizada sobre o plano de visualização.

Interaction Techniques for 3D Modeling on Large Displays

Após alguns estudo preliminares sobre interacção com objectos 3D e uma contextualização dos problemas inerentes ao uso de large displays no contexto da industria automóvel, neste artigo Bill Buxton apresenta uma protótipo para construção de modelos 3D no contexto de ambientes de visualização de larga escala usando dois dispositivos multi sensores.

O artigo aponta a necessidade de este tipo de ambientes possuírem uma interactividade mais rica e assim tenta transpor a metáfora do “tape drawing” usada no passado da industria automóvel para a criação de modelos 3D em escala real. O artigo apresenta assim uma aplicação interactiva em ambientes de visualização de larga escala usando como dispositivos de interacção: “Ascension Flock-of-Birds six degree-of-freedom tracker”

Large Displays in Automotive Design

Outro artigo interessante do Bill Buxton, que analisa o uso de Large Displays no contexto da industria automóvel.

A industria automóvel possuir requisitos muito próprios no que diz respeito ao desenho e validação de novos automóveis, várias técnicas foram usadas no passado como esboços, desenhos, plantas etc…

Com o desenvolvimento tecnológico é hoje possível tirar partido de grandes superfícies de visualização muitas vezes interactivas de forma a visualizar modelos muitas vezes em tamanho real.

O artigo apresenta ainda uma analise de vários ambientes deste tipo, apresentando uma aplicação real deste tipo de cenários.

GEdit: a test bed for editing by contiguous gestures

No seguimento do artigo anterior onde se faz um estudo exploratório sobre o uso de interfaces gestuais, este artigo expõe já uma aplicação das metáforas apresentadas, sugerindo metáforas como:

• Círculos em torno de objectos para selecção de um ou grupos de objectos
• Uso do drag para movimentar objectos
• Traçar uma linha sobre objectos para apagar os mesmo

O artigo remonta o ano de 1991.

É interessante perceber de que forma é que estes conceitos poderão ser aplicado no contexto de visualização de larga escala para enriquecer as possibilidades de interacção com cenas 3D.

CONTINUOUS HAND-GESTURE DRIVEN INPUT

Encontro-me neste momento a ler alguns artigos do Bill Buxton referentes ao seu trabalho na área de interacção, o primeiro artigo que me merece destaque é este que vos apresento, escrito em 1983 expõe um estudo sobre interacção através de gestos usando um sketch-pad.

O estudo procura perceber de que forma é que o uso deste tipo de gestos pode melhorar tarefas como selecção e movimentação de objectos propondo algumas metáforas que já encontrei em outros trabalhos.

“In everyday life, physical gestures are a powerful means of communication. A set of physical gestures may constitute an entire language, as in sign languages. They can economically convey a rich set of facts and feelings. For example, waving one’s hand from side to side can mean anything from a “happy goodbye” to “caution”. Use of the full potential of physical gesture is also something that most humancomputer dialogues lack.

Experimentation with gestures and their composition is essential. For this, powerful programming environments are required. These environments do not currently exist, and consequently gesture-driven dialogues can be unreasonably difficult to implement. Future programming environments must facilitate experimentation with gesture-based dialogues with the same simplicity and efficiency that parsergenerators currently permit with command languages, and User Interface Management Systems permit with menus.”

Usability evaluation considered harmful (some of the time)

I found out a great article in the proceeding of ACM CHI 2009 conference about how usability evaluation can be considered harmful in the development of HCI.

This article defend that usability evaluation is now a standard in research and in academia but many times this evaluation can limit new ideas since they often cannot be tested with the available metrics.

Although in most f the cases this evaluations can accomplish their objectives is not clear that they can do it in all the cases especially in the cases where we have a clear lack of quantitative metrics.

“Within HCI research and academia, researchers employ usability evaluation to validate novel design ideas and systems, usually by showing that human performance or work practices are somehow improved when compared to some baseline set of metrics (e.g., other competing ideas), or that people can achieve a stated goal when using this system (e.g., performance measures, task completions), or that their processes and outcomes improve.

Clearly, usability evaluation is valuable for many situations, as it often helps validate both research ideas and products at varying stages in its lifecycle. Indeed, we (the authors) have advocated and practiced usability evaluation in both research and academia for many decades. We believe that the community should continue to evaluate usability for many – but not all – interface development situations. What we will argue is that there are some situations where usability evaluation can be considered harmful: we have to recognize these situations, and we should consider alternative methods instead of blindly following the
usability evaluation doctrine. Usability evaluation, if wrongfully applied, can quash potentially valuable ideas early in the design process, incorrectly promote poor ideas, misdirect developers into solving minor vs. major problems, or ignore (or incorrectly suggest) how a design would be adopted and used in everyday practice.

ACM CHI 2008 Guide to Successful Submissions states:
“does your contribution take the form of a design for a new interface, interaction technique or design tool? If so, you will
probably want to demonstrate ‘evaluation’ validity, by subjecting your design to tests that demonstrate its effectiveness.

ACM CHI publications: evaluations are dominated by quantitative empirical usability evaluations (about 70%) followed by qualitative usability evaluations (about 25%).”
