They also both have a feature I haven't heard about called "Gesture Lock," which allows you to wake the phone and go directly to a menu or other item depending on the gesture you draw.
In our regression analysis, these values vary from item to item depending on the predictor variables.
On the other hand, IRT gives different point to each item depending on the difficulty of the question [ 14]. i.e., IRT allows the responses (raw scores) from different items representing different severity.

Confusion over the nature of LSI arises because items forming scales have to covary [ 2] and this can imply some stochastic dependence; in other words, that variance in one item depends on the variance in another.
Elsewhere are presented statistical models for user preferences, where the frequency of an item depends on the user preference and item accessibility.
This is an advantage of IRT, since estimations of the person and item parameters are invariant to each other and can be scaled together so that the probability of a correct response to an item depends on the item difficulty and the test-taker's ability level only (Gonzalez and Rutkowski 2010).
One of the models associated to Item Response Theory is the Rasch model, according to which the probability of a person responding correctly to an item depends on the difficulty of the item and on the person's ability regarding the latent trait (Rasch, 1980).
Traditional approaches to measurement scales rely on averages or a simple summation of the test scores; IRT models instead reflect the assumption that the probability of solving an item depends on the test taker's latent trait or ability (i.e., θi = person parameter), combined with the item difficulty (i.e., δi = item parameter).
