Abstract

The incorporation of requirements and recommendations derived from task studies into the graphical interface design process has been characterized by a tendency to overlook task mental load. The inclusion of mental load in the constraints of the conceptualization stage of the design process is gaining more relevance with the rise and democratization of intermediary-free digital exchanges of valuable user data. The pressure of time demands, effort, performance, and frustration in decision-making affects usability and, consequently, the conceptual decisions of the visual and functional design of the interfaces where these decisions take place. This pre-experimental research article provides a descriptive analysis of the task sequences involved in digital information exchange through electronic contracts on the Chia Network (a blockchain platform). First, feasible measurement instruments applicable in these contexts were selected, followed by a simulation to observe the mental workload indices of the tasks of creating and accepting exchange offers. It is proposed to incorporate mental workload measurements into the relevant characteristics used for ergonomic recommendations during the conceptual phase of the digital graphical interface design process, enabling designers and engineers to make more informed decisions.

Keywords: sequences, usability, offer, cognitive ergonomics, NASA-TLX, Human-Computer Interaction (HCI), blockchain.
