Multimethod UX triangulated approach for multiuser interface evaluation

用户界面的开发和测试通常考虑到单个用户。然而，很大一部分接口经常同时被两个或更多的用户使用！例如，在家庭环境中，许多重要的购买（例如，车辆，房屋，旅行安排）涉及多个用户在交易前通过单个界面进行在线搜索，根据Ipsos，这占在线家庭购买的53%。2018年，电子商务在加拿大是一个价值42.6亿美元的产业，加拿大零售商在多用户界面（MUI）评估领域提升知识和方法至关重要。考虑到它的重要性，用户体验（UX）在MUI上下文中的主题还没有得到充分的研究，改进的MUI设计可能会对多个部门产生巨大的生产力影响。这个项目是基于我在过去几年里作为NSERC工业研究主席（IRC）在UX方面所取得的巨大进步。我的研究项目集中在理解用户在真实人机交互（HCI）环境中的认知和情感状态。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来获取和分析多模态神经生理学数据。我的研究在学术界和工业界都有很大的影响，因为它使得通过考虑用户的实际体验来对新的软件界面进行用户体验评估成为可能。因此，本提案提出了一个研究计划，该计划将专注于开发新的方法、工具和措施，以测试涉及两个或更多个人的多用户界面，包括享乐和工具环境。为此，该计划提出了几个研究方向，以进一步了解这一现象，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。这个研究项目主要依赖于HEC montracimal的世界级技术实验室（T3L），该实验室由cfi资助，由我共同创立并指导。该研究计划依赖于一系列实验，这些实验将在位于Tech3Lab的实验小组室内进行。在实验过程中，将使用广泛的神经生理学测量来捕捉受试者的认知、情绪和注意力状态。这笔研究经费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，并在我们领域的主要期刊上发表论文。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在学术和研究实验室都能保持100%的安置率，其中绝大多数是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.
