The ability to observe and measure rapid changes in behaviour is the key to understanding many of the most significant problems in both civil engineering and human interaction. In Canada the civil engineering community faces pressing challenges in how to assess the risk associated with (i) climate change driven landslides, (ii) aging reinforced concrete infrastructure and (iii) deteriorated railway foundation systems. As recent events across Canada and around the world have illustrated, landslides can have a devastating effect on surrounding populations and transportation networks. And yet there is little understanding of the key drivers of these rapid events including the effect of increasingly severe weather events associated with climate change. Many reinforced concrete structures that were built in the mid-twentieth century are approaching the end of their design lives but cannot all be replaced. Instead a better understanding of their performance is required so that they are repaired or replaced only when necessary without compromising the safety of the Canadian public. Similar issues exist on Canadian railways where a wholesale replacement of tracks is impossible and so localized repairs must be used. However detecting which areas of track require repair and ensuring that these repairs are effective is difficult to do. What links each of these areas is the need for robust dynamic data sets that will allow engineers to better understand and predict behaviour. A similar need exists in psychology where dynamic and subtle changes in facial expressions are the key to understanding this aspect of human interaction.

观察和衡量行为快速变化的能力是了解土木工程和人类互动中许多最重要的问题的关键。在加拿大，土木工程社区面临着如何评估与（i）气候变化驱动的滑坡相关的风险，（ii）衰老培养基混凝土基础设施以及（iii）恶化铁路基金会系统的挑战。正如加拿大及世界各地的最近事件所说明的那样，滑坡可能会对周围人口和运输网络产生毁灭性影响。然而，对这些快速事件的关键驱动因素几乎没有理解，包括与气候变化相关的日益恶劣天气事件的影响。二十世纪中叶建造的许多钢筋混凝土结构正在接近其设计生活的尽头，但不能全部取代。取而代之的是，需要更好地理解其性能，以便仅在必要时就在不损害加拿大公众安全的情况下进行维修或更换。在加拿大铁路上存在类似的问题，在加拿大铁路上批发更换轨道是不可能的，因此必须使用本地化的维修。但是，检测到哪个轨道需要维修并确保这些维修有效。这些领域中的每个领域的联系是需要强大的动态数据集，这将使工程师能够更好地理解和预测行为。在心理学中存在类似的需求，即面部表情的动态和微妙的变化是理解人类相互作用这一方面的关键。
