The premise for this is twofold: 1. Throughput cannot be calculated on a single trial. 2. A sequence of trials is the smallest unit of action for which throughput can be attributed as a measure of performance. how far is shoreline from kent wa

WebNumerous independent variables appear in Fitts' law experiments, such as device (e.g., Card, English, & Burr, 1978; Epps, 1986; MacKenzie, Sellen, & Buxton, 1991), transfer function (Jellinek & Card, 1990; MacKenzie & Riddersma, 1994), or system lag (MacKenzie & … Fitts's law (often cited as Fitts' law) is a predictive model of human movement primarily used in human–computer interaction and ergonomics. The law predicts that the time required to rapidly move to a target area is a function of the ratio between the distance to the target and the width of the target. Fitts's law … See more The original 1954 paper by Paul Morris Fitts proposed a metric to quantify the difficulty of a target selection task. The metric was based on an information analogy, where the distance to the center of the target (D) is … See more The formulation of Fitts's index of difficulty most frequently used in the human–computer interaction community is called the Shannon … See more Not long after the original model was proposed, a 2-factor variation was proposed under the intuition that target distance and width have separate effects on movement time. … See more Fitts's law deals only with targets defined in space. However, a target can be defined purely on the time axis, which is called a temporal target. A blinking target or a target moving … See more A movement during a single Fitts's law task can be split into two phases: • initial movement. A fast but imprecise movement towards the target • final movement. Slower … See more An important improvement to Fitts's law was proposed by Crossman in 1956 (see Welford, 1968, pp. 147–148) and used by Fitts in his 1964 paper with Peterson. With the adjustment, … See more Extensions to two or more dimensions In its original form, Fitts's law is meant to apply only to one-dimensional tasks. However, the … See more WebDay 1, soak the seeds (this experiment uses Peas, Little Marvel) overnight in water.
