  • Publication number: 20240086514
    Abstract: The purpose of the present invention is to provide a portable terminal and an application software start-up system whereby the application software that is started up is limited depending on the state of a user, thereby providing an improved ease of use. For this purpose, an application software start-up method for an information processing device comprises: performing identity authentication based on static biological information; determining the state of the user by comparing dynamic biological information acquired from the body of the user with previously measured dynamic biological information; and limiting the application software that is started up in accordance with the determined state of the user and on the basis of a permission level that is set in advance for each application software item.

  • Patent number: 10883880
    Abstract: An optical characteristic evaluation method evaluates unevenness of an optical characteristic in an optical film based on analysis of a polarized state of light transmitting through an optical film and an analyzer. The method includes the following, measuring a phase difference and an orientation angle in a plurality of positions; and quantifying and evaluating the unevenness of the optical characteristic based on a parameter of a vector of output light calculated by a formula 1 using a vector showing a polarized state of input light and a matrix showing a polarizing characteristic of the optical film and the analyzer. The formula 1 is as follows, formula 1: F2=M×F1, F1: Stokes vector or Jones vector of input light, F2: Stokes vector or Jones vector of output light, M: Mueller matrix or Jones matrix of the optical film as the evaluation target and the analyzer.
