How to Develop Adaptable JavaScript User Interface

Resilience is endogenous to the website and so for the web developers. This guide finds out how graceful watchful coding, perceptibility, and a positive viewpoint towards failures better strengthens us before, during, and post an issue occurs.

Adapting the fragility of the web equips us to develop User Interfaces able to adapt the functionality they can provide whilst still offering quality to users.

Stuff on the web can crash – the issues are piled up against us. Several things can go wrong: a server request can get failed, a JavaScript feature can become unsupported (presuming JavaScript is even accessible), a third-party library crashes, a CDN may go down, user behavior may get unexpected (user can double-click on a submit button), and the list is ongoing.

Luckily, software engineers can cast aside or at least minimize the effect of crashes in the web apps they develop. However, this needs a conscious attempt and mindset to focus on thinking about unexpected cases just as much as expected ones.

The UX doesn’t require to be what is usable. This area, called graceful degradation, enables a system to sustain functioning when elements of it are dysfunctional. It is more like an e-bike becomes a basic bike at the time its battery dies. So, if something fails just the functionality incumbent on that should be affected.

Thus, UIs should embrace the functionality they can provide while offering as much quality to end-users as possible.

Why Be Resilient?

It is because resilience is intrinsic to the website.

Web browsers avoid unsupported CSS properties and invalid HTML tags. This generous attitude is called Postel’s Law, which is delivered very well by Jeremy Keith in the Resilient Web Design field.

Whilst JavaScript is a little forgiving, and resilience is extrinsic. We direct JavaScript for what to do if something unannounced happens. If an API request fails, the responsibility falls on the web developers to find the error and afterward decide what to do. And the decision has a straight impact on users.

Adaptability develops trust with users. An errorful experience impacts poorly on the brand. As per Kim and Mauborgne, ease of use (availability, convenience) is one of the six features allied with a powerful brand, which makes graceful degradation selfsame with brand sensibility.

A powerful and trustworthy UX is a hint of value and reliability, both of which are put into the brand. If a user is unable to do a task due to something that went wrong they will eventually face disappointment. They could be allied with your brand.

Usually, system failures are mentioned as “corner cases.” It often refers to the things that barely happen. Though, the web has several corners. Distinct web browsers are functioning on different platforms and devices, concerning our user choices web and browsing modes, being served to geo-locations. They get served with fluctuating latency, and intermittency raises the possibility of something not functioning as supposed.

Proposed Method

To study and build resilient and adaptable user interfaces to assure safety and ecosystem sustainability in a regular daily living space, socialization, a new way of a collective and adaptive user interface is introduced to support the structuring of information concerned to the user and the context of the communication to produce singular user profiles.

This implements the definition and building method of holistic and adaptive user interfaces to satisfy the various utilization contexts/profiles and user skills/requirements. The main aim of this task is the development of new ways for human-machine communication and user interfaces, as per the “design for all” paradigms. The UIs will be resilient, which means they will be simple to use and user-friendly, including the weak and elderly population. The novel UIs will react according to human behavior and communicate as per the environmental conditions tracked by local sensors. The adaptation management feature is dependent on the information given by three information models: The User Model, the Domain Model, and the Interaction Model.

The User Model information feature details the user’s profile pattern, as per its physical and cognitive structure, status, and choices. The user’s profile pattern is drawn under the instructions given by the International Classification of Functioning, Disability, and Health (ICFDH).

Whilst, the Environment Model (EM) delivers the information pattern crucial to explain the ecosystem of the human-machine interaction. This information is concerned with its peripheral characteristics (such as typology of an interactive machine, existing means of interaction, etc.) as to its workings (for instance, supported tasks or activities) and its logical characteristics (like knowledge concerns to management of the system working done by the adaptive interface).

At last, the Interaction Model (IM) is the main part of the entire adaptive process. The interaction model is dedicated to handling the user and environmental data management. This model needs to identify the user and collect its requirements and preferences. Furthermore, it has to be capable of fetching human-computer communication data, offer accurate logical and task interpretation. Plus, it allows a much more adaptive environmental usability and explains the task activation schedule. Such complex adaptive features need evaluation and inference mechanisms, which require learning and communication with the local ecosystem.

The Adaptive mechanism doesn’t offer any direct access to the entire domain reality; the machine to be built must perform within a range of indefinite information: unreliable, lost, and improper data. And incorrect environmental information may increase inaccuracy. However, probabilistic theories offer ways to deal with improper data systems, resulting in less domain knowledge accurately. The Bayesian method gives a strong theory that blends various technologies.

Self-learning is based on the thought that experience may enhance the “agent” potential behavior and forthcoming events, offering the capability to automatically upgrade users’ profiles and estimate users’ behavior.

Resilience and Resilient System Architecture

Depending on the model, a basic view of the layout for handling the user interfaces deployment has been conceived as given.

The system layout depends on 3 primary units, seamlessly communicating with each other: the core engine, the database, and the user interface.

A Database Management System is developed to accomplish a huge stack of aligned data inputs and processes the requested data by thousands of users. The DBMS unit is dedicated to storing the data coming from the various inputs of the system. In addition, the data is aligned in four semantic segments like User Features Profile, User Use Profile, Log Adaptation Actions, and Context Data.

Whereas, User Features Profile comprises the user’s personal data as explained in the user identification. Then comes the User Use Profile, which consists of the user model context data: user’s choices, previous communication history, and information requirements. Thereafter, Log Adaptation Actions comes, which shows the storage of all adaptation actions done by the interface. Log Adaptation Actions fetch the data each time that the device performs an adaptation action.  This information is crucial to monitor and control the device’s adaptation degree and, at the same time, the user’s skills enhancements in the process. At last, Context Data comes, upon which all concerned data is collected for the context user definition of the device. It shall track the data derived from environmental sensors allied with temporal coordinates.

The main module shows the whole adaptive system pivot. It is made up of two adaptive mechanisms and a tracking system of variations. Adaptable Engine is supposed to make the system adaptable as per the user profile. As resilience is based on quality and choices that are known at the very first interaction, they are supposed to remain static when a single interaction session is ongoing.

This engine receives as input the stored data in the User Profile Features to embrace the graphical UI features, such as text, type of font, and font size. Resilience is based on change mechanisms. This mechanism involves all dynamic features, like information contents, interaction story-based preferences, icons, structures, and so on. The functioning systems take advantage of the Bayesian Network adaptation mechanism with the help of the software called Netica. It is dependent on the data by User Features, User Use, and Context Data database sections, and implements improvements on the Interface level, which are contents and graphics (dynamic).

Change monitoring feature lets you produce two alert types such as User Preferences Changes and User Abilities Changes. User Preferences Changes consider the user preferences changes in terms of both content and graphics. Whereas User Abilities Changes allow the interface changes, collect them, and generate an alert if they frequently change, both positively and negatively, going to upgrade the User Features Profile. At last, the interface module lest you are enabling device interaction with the user.

The system recognizes two kinds of users. First, the consumer, who is the target user and whom the adaptation support process is applied on. The specialist who represents the connection point among ICT feature and health condition analysis of the consumer. The interface layout can be broken into two given aspects. Graphics can be avail of regular features, i.e., standard features surprisingly related to a disability such as color blindness and other visual disorders. These features are concerned with the lack of proper body functionalities and sustainability with available guidelines.

Whereas advanced tools show all dynamic features of embraced interface stuff as per the particular residual work result to a particular disorder and are developed on a single user.

Contents include all interface stuff editable as per the user and actions the user performs on an interface, own choices, and requirements. For example, assuming a kitchen, if the user wants to enter the oven area, the system will provide evidence of a more used process. At last, Configuration Wizard is a feature that can let you modify the User Preferences and the Clinical Evaluation. It offers a high-level questionnaire to clinical parameters configuration.
