A Case Study on the Context-based UI Design in the Women’s Fashion Mobile Shopping Mall

Increasing demands on user interface (UI) usability, adaptability, and dynamic behavior drives ever-growing development and maintenance complexity. Traditional UI design techniques result in complex descriptions for data presentations with significant information restatement. In addition, multiple concerns in UI development leads to descriptions that exhibit concern tangling, which results in high fragment replication. Concern-separating approaches address these issues; however, they fail to maintain the separation of concerns for execution tasks like rendering or UI delivery to clients. During the rendering process at the server side, the separation collapses into entangled concerns that are provided to clients. Such client-side entanglement may seem inconsequential since the clients are simply displaying what is sent to them; however, such entanglement compromises client performance as it results in problems such as replication, fragment granularity ill-suited for effective caching, etc. This paper considers advantages brought by concern-separation from both perspectives. It proposes extension to the aspect-oriented UI design with distributed concern delivery (DCD) for client-server applications. Such an extension lessens the serverside involvement in UI assembly and reduces the fragment replication in provided UI descriptions. The server provides clients with individual UI concerns, and they become partially responsible for the UI assembly. This change increases client-side concern reuse and extends caching opportunities, reducing the volume of transmitted information between client and server to improve UI responsiveness and performance. The underlying aspect-oriented UI design automates the server-side derivation of concerns related to data presentations adapted to runtime context, security, conditions, etc. Evaluation of the approach is considered in a case study applying DCD to an existing, production web application. Our results demonstrate decreased volumes of UI descriptions assembled by the server-side and extended client-side caching abilities, reducing required data/fragment transmission, which improves UI responsiveness. Furthermore, we evaluate the potential benefits of DCD integration implications in selected UI frameworks.

Bodily Movements

Designing embodied playfulness has been explored as a method for problem-solving. However, when thinking about deploying such an approach in public space activities, we often face many limitations regarding safety and ambiance, especially for bodily movements and behavior. To explore and address the challenges of deploying playfulness with restrained bodily movements in public spaces, we present a case study of an escalator augmented with auditory and visual feedback. An escalator in a public shopping mall has many limitations that require careful consideration in the design to maintain safety and avoid mistakes. We describe the challenges of our design strategy in order to complete the installation of a public escalator over five days. The results show that our approach significantly encouraged people to use the escalator, and also improved their manner of using it. Our work presents a successful method of treating the balance of social limitations and enjoyment that can affect human behavior in positive ways.

New Facility

In view of the problem of competitive facility location in urban planning, the response of competitors to the new facility is considered. We use Huff’s probability model to describe the market share of all facilities which depends on its service quality and its distance from customers. To maximize the market share of facilities, a two-stage method (quality decision stage and location decision stage) is adopted, which takes into account the responses of competitors. In the stage of quality decision, the competitive decision-making process is simulated as a game process and solved by Nash equilibrium. The solution of the quality decision process can be expressed as a function of the new facility’s location which can be obtained by polynomial approximation. In the location decision stage, we apply the interval analysis based on branch and bound algorithm to determine the optimal location of new facility. Then, we use the randomly generated numerical experiment to verify the effectiveness of the model and algorithm. Finally, we apply this model and algorithm to the location of a new shopping mall in Putuo district, Shanghai.

Easy Integration

We analysed four Rational Unified Process (RUP) projects in Switzerland that identified themselves as following a user-centred approach. Grounded theory served for analysis of 12 interviews with software developers, project managers, and UI specialists. For each professional group we analysed their work context, motivations, work practices, and strategies used to overcome the obstacles to user-centred design. Results show that end users did not participate in the projects. Instead of working directly with end users, participants used data from marketing research or consulted colleagues from other departments. Prototypes played an important role. We suggest the following remedies: (1) developing methods for easy integration of existing company knowledge about products with usability features, (2) professionalising UI design by educating project stakeholders in standard UI design, (3) creating an approved pool of company's personas for UI specialists' work, and (4) educating customers on their right to get good user interfaces.
