    Fitts' law Fitts's law (often cited as Fitts' law) is a predictive model of human movement primarily used in human-computer interaction and ergonomics. This scientific 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[1].

The theoretical basis for Fitts' law is developed and extended. Several modifications are claimed to improve the model's prediction power in general, and to extend its applicability to movement tasks common on today's interactive computer systems.

Home Browse by Title Theses Fitts' law as a performance model in human-computer interaction Fitts' law as a performance model in human-computer interaction January   Summary This chapter examines Fitts' law beginning with its introduction in and extending to contemporary use of the law in human‐computer interaction.

Fitts' original experiments are reviewed and follow‐on modifications to the law are explained. Fitts' law as a performance model in human-computer interaction. Doctoral dissertation. University of Toronto: Toronto, Ontario, Canada.

Fitts’ law states the log-linear relationship between the amplitude of the movement (A), the target width (W), and the mean movement time (MT). Fitts believed that a person has Fitts law as a performance model in human-computer interaction book adapt to a difficult Fitts law as a performance model in human-computer interaction book of A and W by increasing the MT or by becoming less accurate, because the amount of information a human neuro-motor system can process is limited.

Fitts's Law is basically an empirical model explaining speed-accuracy tradeoff characteristics of human muscle movement with some analogy to Shannon’s channel capacity theorem.

Today, with the advent of graphical user interfaces and different styles of interaction, Fitts’ Law seems to have more importance than ever before. Fitts’ Law is an intensively used theory in Human-Computer Interaction. It can be used in assisting interface designs (the invention of pop-up menus) and in interface evaluation (e.g., “embedded model” in).

Another prevalent use of Fitts’ Law is File Size: KB. Douglas J. Gillan, Kritina Holden*, Susan Adarr^, Marianne Rudisil^ and Laura Magee* The paper challenges the notion that any Fitts' Law model can be applied generally to human-computer interaction, and proposes in- stead that applying Fitts' Law requires knowledge of the users' sequence of movements, direction of movement, and typical move- ment amplitudes as Cited by: • A model of human movement • Paul Fitts, a (before HCI existed!)

Abstract According to Fitts' law, human movement can be modeled by analogy to the transmission of information. Fitts' popular model has been widely adopted in numerous research areas, including kinematics, human factors, and (recently) human-computer interaction (HCI).Cited by: Fitts’ particular interest was rapid‐aimed movements, where a human operator acquires or selects targets of a certain size over a certain distance.

Fitts law as a performance model in human-computer interaction book proposed a model—now “law”—that is widely used in fields such as ergonomics, engineering, psychology, and human‐computer interaction. Fitts Law is a model of human movement primarily used in human–computer interaction that predicts that the time required to rapidly move to a target area is a function of the distance to the target and the size of the target.

Fitts’s law is an unusually successful and well-studied model. Fitts' Law Models One of the most robust and highly adopted models of human movement is Fitts' law [4,5]. The model is, arguably, the most successful of many efforts to model human behavior as an information processing activity. (For detailed reviews, see [10,12,20].) Fitts was interested in applying information theory to measure the difficulty.

Abstract Fitts’ law is a performance model of human movement especially the act of pointing which is widely used in Ergonomics and Human-Computer Interaction. The. Fitts's law is a predictive model of human movement primarily used in human–computer interaction and ergonomics.

This scientific 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 is used to model the act of pointing, either by physically touching an object with a. Fitts’ law states that the amount of time required for a person to move a pointer (e.g., mouse cursor) to a target area is a function of the distance to the target divided by the size of the target.

Thus, the longer the distance and the smaller the target’s size, the longer it takes. Human Performance Haptic Input 14 September, Buxton Chapter 8: HUMAN PERFORMANCE Introduction As you will find in this book, computer input device design, and use, reflects a variety of choices in multiple dimensions.

Fitts' law is only one of the many theoretical products of decades of human motor control studies. 1 Introduction Since its proposal inFitts’ law [ 1] has became probably the most studied performance model in the area of Human-Computer Interaction.

Both techniques were accurately modeled by Fitts' law in all gain settings except for when there was a significant amount of clutching. From our results, we derive a usable range of CD gain settings between thresholds of speed and accuracy given the capabilities of a pointing device, display, and the expected range of target widths and by: Human performance in selection tasks is frequently described by Fitts' law, which states that the average time needed to move to a target and select it is linearly related to the index of difficulty for the task, which is the logarithm of the task characteristic C=A/W, where A is the target distance and W is the target width.

The coefficients in this linear relationship can vary across Cited by: 2. According to Fitts' law, human movement can be modeled by analogy to the transmission of information.
