Iwu Fitts na-ekwu na ka ihe mgbaru ọsọ na-adị anya ma dịkwa obere, otú ahụ ka ọ na-ewe ogologo oge iji kụọ ya. N’afọ 1954, Paul Fitts gosiri na oge ahụ na-abawanye n’ahịrị kwụ ọtọ ka “ọnụọgụ ihe isi ike” nke ihe mgbaru ọsọ si dị, a na-atụkwa ya na bit [1]. Taa, a na-edekarị ya dịka log2(distance / width + 1) [2]. Ndị na-emepụta ihe na-eji ya eme bọtịnụ ndị dị mfe ịpị.
