  • Ergonomic soft mouse and armrest mouse pad

    In this paper, it is shown that a teddy bear skin spongy mouse is a better option than a conventional plastic mouse design and that a portable arm rest mouse pad platform is far better than the conventional mouse platform placed to the side of the keyboard tray. Both designs help reducing arm abduction and related discomfort, pain, fatigue and soreness. Ten people voluntarily participated in the task and completed a series of psychophysical questions (Borg RPE [Rate of Perceived Exertion] Scale was used to evaluate). Results indicate a much smaller perception of pain and discomfort on palm and wrist with the spongy mouse rather than conventional designs, especially to palmar aponeurosis and ulna muscles. The mouse pad greatly reduced all the pressure points of hand and added comfort on wrist and forearm (e.g. flexor retinaculum (FR) and palmaris longus muscle area).

  • Interfaces for staying in the flow
    Psychologists have studied "optimal human experience" for many years, often called "being in the flow". Through years of study, the basic characteristics of flow have been identified. This paper reviews the literature, and interprets the characteristics of flow within the context of interface design with the goal of understanding what kinds of interfaces are most conducive to supporting users being in the flow. Several examples to demonstrate the connection to flow are given.
