Compute Similarity Between Scanpaths

This function computes the similarity between two scanpaths using a specified method.

Usage

# S3 method for class 'scanpath'
similarity(
  x,
  y,
  method = c("multimatch"),
  window = NULL,
  screensize = NULL,
  ...
)

Arguments

x

A scanpath object containing the first scanpath.

y

A scanpath object containing the second scanpath.

method

A character string specifying the method to compute the similarity (default is "multimatch").

window

A numeric vector of length 2 specifying the time window to restrict the fixations in the input scanpaths (default is NULL, which considers all fixations).

screensize

A numeric vector of length 2 specifying the dimensions of the screen (e.g., c(1000, 1000)). Required for the "multimatch" method.

...

Additional arguments passed to the similarity computation method.

Value

A numeric value representing the similarity between the two input scanpaths.

Examples

# Example usage of the similarity.scanpath function
scanpath1 <- # first scanpath data
scanpath2 <- # second scanpath data
similarity_value <- similarity.scanpath(scanpath1, scanpath2, method = "multimatch", screensize = c(1000, 1000))
#> Error in similarity.scanpath(scanpath1, scanpath2, method = "multimatch",     screensize = c(1000, 1000)): could not find function "similarity.scanpath"
