Human Centred Interface- A new thinking
In the era of technology, HCD is a process used across industries and sectors. It is inspired by behaviours rather than Demographics, takes place in natural contexts instead of controlled settings and relies on dynamic conversations rather than scripted interviews. However, the conventional methods are failing to provide the efficient design.
The success of any product is determined by end user but now-a-days many users are increasingly concerned with social impact and environmental issues. All these elements must be kept in mind while choosing product design.
Approach to human centred interface:
- Design thinking and HCD - Design thinking for the utilization of HCD approach is a wide range of Fields, not just a design. It applies the principles and techniques that form the core of Design Thinking to fields as diverse as corporate strategy, service planning, product planning/development, market creation, business process improvement and research planning. Design thinking has set forth a methodology comprised of five steps: “Understanding” “Observation”, “Visualization”, “Evaluation”, “Revision” and “Implementation” using tools for fieldwork, prototyping, user testing, and brainstorming.
- Utilizing Design Thinking - The creative design approach requires a different set of assumptions rather than conventional approaches, or rather it requires abandoning those assumptions altogether. The key to this is what is called "reframing."
- Reframing Approaches - In reframing from a user design perspective, Design team needs to perform reframing by taking advantage of a HCD with a different frame on their own. For example, if the design team has to design Toothbrush for children, they can’t think from the perspective of adults as a child holds their toothbrush differently. Now the design team would develop their plans by shifting perspective to that of a child.
- Axis of various users - Reframing is also possible by shifting to the viewpoints of various users and cultures. For instance, the Lead User method can be seen as reframing approach that uses a user’s view point. Conception while understanding with users using the Personality method is also reframing from the viewpoint of various users.
- SCD and HCD - The HCD methods focuses on the users while designing any product both user and business are taken into consideration. In the past few years, society and environment have come to exert a greater effect on customers and businesses, not only shaping their values, but imposing various restrictions or demands upon them. To deal with these changes, HCD approaches have been modified to take account of the social environment.
- Positioning of SCD - Studies has shown that the SCD(Social Centered Design) is now achieving prominence as a powerful solution-based approach capable of dealing with today’s most urgent issues. The Vision-Proposal Design methodology for future proposals is composed of a user’s viewpoint, business viewpoint and a structural scenario method part (which is the core of this design Methodology). There is no positioning or society and the environment in this methodology rather, it is included in the user’s viewpoint or positioned in the business viewpoint.
- SCD Approach - When society and environment are included in the beginning process, the social environment perspective is added to a business model, conscious of customer value.The Business Model enables easy-to-understand utilization of a business model with separate templates each from a different standpoint - user, business, and profit/cost.The values of customers and businesses relevant to society and the environment, as well as social and environmental trends can be described in the social environment design.
- Social Experience Approach - When taking an SCD approach to Design Thinking, a social experience perspective is required. The HCD approach requires two proposals; one from a user’s viewpoint (proposition of UX) and another from a business viewpoint (proposition of a business model). The SCD approach adds on another two propositions also from a user’s viewpoint and a business viewpoint; the former is “proposition ofSX” and the latter is “proposition of social environmental business(Business + SE) model.”
Design thinking and SCD based on HCD can propel innovation in a fast-changing world. Techniques such as reframing from the viewpoint of UX, social environment business models, and SX are also essential to achieve Design Thinking and SCD, which are powerful and effective tools for implementing solution-based concepts to solve problems and develop new products.
