Design methodologies in Human-Computer Interaction (HCI) differ from their various design perspectives and circumstances. Several methodologies have carried out in HCI design and their role of activities are distinct. For user-centric interaction and user interface design, the methodologies indicated to holistic manner. Modern technologies have grown faster and the user connections with modern equipment have comprised brightly. In HCI the methodologies are user concerned, depended on task, user values and experiences. The methodologies are set of process, logical approaches, and instructions which follow in developments. The broadly used HCI design methods, models or approaches are Activity Theory (AT), User-Centered Design (UCD), Value Sensitive Design (VSD) and the Mental Model applied on interaction design. The modern aspects of technology have switched into extensive digital phenomena as touch and sensor-based technology from GUI and Physical user interfaces into Natural user interfaces. In this paper has been analyzed the existing design methodologies in HCI and extended advanced and simultaneous conceptual approach which referred to as future HCI design approach for next-generation application design.
