Since the adoption of portable devices like smartphones or smartwatches, the usage of applications has rapidly increased for supporting diverse daily activities from connecting with friends to measuring running distance. Since the Apps are an ubiquitous tool in everyday life, it is also an opportunity for a new digital business model. However, there are legacy applications implementing the core business process and rules that are not designed to run properly on new mobile devices. The migration of legacy applications by developing a new version from scratch introduces risk and uncertainty. This study proposes an approach to assist the migration of legacy Apps so that available functionality is prioritized, the experience of User Interface is re-thought, and the new design is evaluated with a preliminary running version of the legacy app. The proposed method is based on a Markov chain model. An experiment on ten participants shows that a dynamic user interface that implements the Markov model provides the users with a better usability. This work suggests that the heuristics make possible a smart and proactive interface design.

自从采用智能手机或智能手表等便携式设备以来，应用程序的使用量迅速增加，可支持从与朋友联系到测量跑步距离等各种日常活动。由于应用程序是日常生活中无处不在的工具，因此它也是新的数字业务模型的机会。但是，有一些遗留应用程序在实施核心业务流程和规则，而这些规则和规则不能在新的移动设备上正常运行。通过从头开始开发新版本来迁移旧版应用程序会带来风险和不确定性。这项研究提出了一种有助于迁移旧版应用程序的方法，以便优先考虑可用功能，重新考虑用户界面的体验，并使用旧版应用程序的初步运行版本评估新设计。所提出的方法基于马尔可夫链模型。对十个参与者的实验表明，实现马尔可夫模型的动态用户界面为用户提供了更好的可用性。这项工作表明，启发式技术使智能和主动的界面设计成为可能。
