Multimethod UX triangulated approach for multiuser interface evaluation

用户界面的开发和测试通常只考虑单个用户。然而，很大一部分界面经常被两个或更多的用户同时使用！例如，在家庭环境中，许多重要的购买（例如，根据益普索的数据，在交易之前，多个用户通过一个界面进行在线搜索（车辆、房屋、旅行安排），这占在线家庭购买的53%。由于2018年电子商务在加拿大是一个价值42.6亿美元的行业，因此加拿大零售商在多用户界面（MUI）评估领域推进知识和方法至关重要。鉴于其重要性，MUI环境中的用户体验（UX）主题尚未得到充分研究，改进的MUI设计可能会对多个部门产生巨大的生产力影响。 这个计划是基于我在过去几年中作为NSERC工业研究主席（IRC）在UX方面取得的巨大进步。我的研究项目专注于了解真实人机交互（HCI）环境中用户的认知和情感状态。为了准确地捕捉用户的状态，我使用与神经科学和心理生理学领域相关的方法，以获取和分析多模态神经生理数据。我的研究在学术界和工业界都有很大的影响，因为它可以通过考虑用户的实际体验来对新软件界面进行UX评估。因此，这项建议提出了一个研究计划，将重点放在开发新的方法，工具和措施，用于测试范围广泛的多用户界面，涉及两个或两个以上的个人在享乐和工具的情况下。为此，该计划提出了几个研究方向，以进一步加深我们对这一现象的了解，同时也提高了多用户体验测量和可视化的有效性，可靠性和诊断性。该研究项目主要依赖于蒙特利尔HEC世界一流的、由CFI资助的Tech 3Lab（T3 L），我是该项目的联合创始人和联合负责人。该研究计划依赖于一系列实验，这些实验将在位于Tech 3Lab的实验室进行。在实验过程中，将使用广泛的神经生理测量来捕捉受试者的认知、情绪和注意力状态。 这笔研究资金将使我们能够为发现铺平道路，使我们能够保持长期的科学领导地位，除了在我们领域的领先期刊上发表。这些进步将直接使加拿大工业受益，加拿大工业需要在数字化转型的最前沿建立自己的地位，特别是在电子商务的关键领域。我希望我的博士和硕士学生的100%就业率将保持在学术和研究实验室，其中绝大多数在加拿大的组织和大学。

User interfaces are generally developed and tested with a single user in mind. However, a significant portion of interfaces are very often simultaneously used by two users or more! For example, in a household context, many important purchases (e.g., vehicle, house, travel arrangements) involve an online search by multiple users through a single interface prior to the transaction, which account for up to 53% of online household purchases according to Ipsos. As e-commerce is a $4.26 billion industry in Canada in 2018, it is crucial for Canadian retailers to advance knowledge and methods in the field of multi-user interface (MUI) evaluation. Given its importance, the subject of user experience (UX) in a MUI context is understudied and improved MUI design could have massive productivity implications across multiple sectors. This program is based on the considerable advancements that I have been able to achieve as the NSERC Industrial Research Chair (IRC) in UX, over the past few years. My research program is focused on understanding the cognitive and emotional states of users in authentic human-computer interaction (HCI) contexts. To accurately capture the user's states, I use methods associated with the fields of neuroscience and psychophysiology in order to acquire and analyze multimodal neurophysiological data. My research has a strong impact in academia and industry as it makes it possible to perform a UX evaluation of new software interfaces by taking into account what the user actually experiences. This proposal thus puts forward a research program that will focus on developing new methodologies, tools and measures for testing wide range of multi-user interfaces involving two or more individuals in both hedonic and instrumental contexts. To do so, the program proposes several research directions to further our knowledge of this phenomenon, but to also improve the validity, reliability and diagnosticity of the measurement and visualisation of multi-user experience. This research program relies primarily on HEC Montréal's world-class and CFI-funded Tech3Lab (T3L), which I co-founded and co-direct. The research program relies on a series of experiments that will be undertaken in an experimental group room located in the Tech3Lab. During the experiment, a wide range of neurophysiological measures will be used to capture the subjects' cognitive, emotional and attentional states. This research funding will allow us to pave the way for discoveries that will enable us to maintain our long-term scientific leadership, in addition to being published in leading journals in our fields. These advances will directly benefit Canadian industry which needs to establish itself at the forefront of the digital transformation, especially in the critical sector of e-commerce. I expect that the 100% placement rate of my PhD and MSc students will be maintained in both academic and research labs, the vast majority of them in Canadian organizations and universities.
