优步的历史可以追溯到2008年在巴黎召开的一次会议。卡兰尼克和坎普这两个孩子经常在讨论出租车的问题时，这个突破性的想法出现在巴黎的灰色云层下(Stone, 2015)。最初，加勒特带头设计了应用程序，这将彻底改变世界。截至2010年，优步已经在纽约和旧金山推出了自己的汽车。正如今天所看到的，该公司估值高达170亿美元，是一个值得分享的成功故事。这家以科技为基础的初创公司传播快乐的面孔，让人们以比以前更快的速度、更简单的方式、更便宜的方式做事。这是问题的核心，因此技术团队有能力使用它以多种方式解决问题。然而，研究清楚地表明，有时需要一些其他模式来解决问题的某些分支(Smith, 2011)。这是问题的理性答案，因为它提供了可用性问题的答案。该属性具体描述了哪些方面需要改进，哪些方面需要更改。这是需要立即注意的最后也是最重要的细节，因为这个属性讨论了概念的实际应用和可用性。
以Uber app为例，它被广泛设计为创造高品质的用户体验。谈到每个人的私人驱动程序的概念，这个应用程序把这带到一个新的层次。这可以帮助用户更多地了解司机，知道谁会送他们去目的地，他们甚至可以询问他们要乘坐的汽车。这个应用程序可以选择了解驱动程序的一些更全面的细节，并优先考虑这些细节(Taylor, 2015)。现在，下次用户使用应用程序时，服务器将搜索优先级驱动程序及其位置，从而为问题提供有利的解决方案。然后是理解和概念化交互的问题。任务是正确理解设计空间概念化的问题，从而开发概念模型(Kurosu, 2014)。Johnson和Henderson提出的概念模型描述了如何组织和操作一个系统，并对其进行了详细的高层描述。概念化空间有很多好处。
Uber dates back to 2008 to a conference in Paris. The two kids Kalanick and Camp were usually cribbing over the issues of cabs when the breakthrough idea emerged under the grey clouds of Paris (Stone, 2015). Initially, Garrett took the lead and designed the applications, which would revolutionize the world. As of 2010, Uber was already rolling cars in the city of New York and soon after in San Francisco.As seen today, the company is highly valued at $17 billion and is a successful story to share. Spreading happy faces, this tech-based startup allows people to do things at a faster pace, in easier ways and a lot cheaper way than before. This is the core of the problem, and the technical team thus has the power to use this to solve the problem in numerous ways. However, the studies clearly show that sometimes, there are some other patterns needed to solve some branches of the problem (Smith, 2011).This is rational answer to the problem as it provides answers to the problems of usability. This attribute specifically describes which aspect needs improvement and which of these needs to be changed.This is the last and the foremost detail which needs immediate attention, as this attribute talks about the real life applicability and usability of the concept.
Considering the example of Uber app, it is widely designed to create quality user experience. Talking about the concept of everyone’s private driver, this app takes this to a next level. This helps the user to know more about the driver who is going to give them a ride to their destination, and they can even enquire about the car they are going to travel in. This application gives the choice to know some more comprehensive details of the driver and also prioritize them for later (Taylor, 2015). Now the next time the user is going to use the application, the servers search up the prioritized driver and their location and thus offer favourable solutions to the problem.Then comes the problem of understanding and conceptualizing interaction. The task is to properly understand a problem of conceptualizing the design space, and hence developing a conceptual model (Kurosu, 2014). A conceptual model according to Johnson and Henderson describes how to organize and operate a system with a detailed high level description of it. There are various benefits of conceptualizing the space.
