Cognitive load scoring of a visual stimulus

A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processing device causes the at least one processing device to perform steps of:

• obtaining an information density matrix for an input visual stimulus, the information density matrix characterizing information density of feature points in the input visual stimulus;
• identifying one or more clusters of feature points in the input visual stimulus by performing spatial clustering of the feature points utilizing the information density matrix;
• determining a cognitive load score for the input visual stimulus based at least in part on the identified one or more clusters of feature points, the cognitive load score characterizing cognitive energy required to mentally process the input visual stimulus;
• and
• modifying a design of the input visual stimulus to adjust the cognitive load score of the input visual stimulus.

A method comprising steps of:

• obtaining an information density matrix for an input visual stimulus, the information density matrix characterizing information density of feature points in the input visual stimulus;
• identifying one or more clusters of feature points in the input visual stimulus by performing spatial clustering of the feature points utilizing the information density matrix;
• determining a cognitive load score for the input visual stimulus based at least in part on the identified one or more clusters of feature points, the cognitive load score characterizing cognitive energy required to mentally process the input visual stimulus;
• and
• modifying a design of the input visual stimulus to adjust the cognitive load score of the input visual stimulus;
• wherein the method is performed by at least one processing device comprising a processor coupled to a memory.
