Physical Interaction Costs (PIC), including complex navigation, dense instructions, unconventional mental models and interaction patterns, etc. 1) Attention and memory The two most important components of Mental Interaction Cost (MIC) are attention executive email list and memory. When a task requires too much attention or memory to complete, it will have a high Mental Interaction Cost (MIC), reducing usability. Some common elements that add to the attention cost or distraction include small pop-ups, content module divisions, eye-catching visuals, executive email list and animations that are unrelated to the user’s current task. Users are easily distracted by these elements. Make sure they don't take their attention elsewhere when they're trying to get things done. 2)
Assess attention An eye-tracking study (ETS) may be considered if an interface is to assess the level of attention paid to Mental Interaction Cost (MIC). Use ETS to infer not only the user's location, but also their thoughts. Two eye-related motor indicators of ETS: "fixation" and "saccade". Gaze occurs when the user's pupil stays on an interface element long executive email list enough. A "saccade" movement occurs when the eye moves - jogging between areas within the interface. If ETS reveals many task-independent jumpy trajectories, it may be because executive email list the interface is distracting. ETS results can help you understand what distractions and unnecessary things are causing users to miss key information in the interface. 3)
Working memory There are broad categories for different types of memory. Working memory (part of short-term memory) is the most relevant in terms of designer roles and responsibilities. The shortest type of memory is called working memory, which executive email list usually lasts only a few seconds during the task. In other words, our working memory is responsible for the information we can grasp while we engage in other cognitive processes. Miller's executive email list Law states that the average person can only keep 5-11 items in their working memory at a time. The working memory required to complete a task in a product is proportional to the mental interaction cost (MIC) burden imposed on the user.
