The display monitor presents the set of alphanumerical characters in a spatial configuration of three parallel horizontal rows or three parallel vertical columns. The “left”-button and the “right” button of the directional buttons of the user-interface control the selection of a group of alphanumerical characters, one of each of the three parallel arrays and positioned in the same column. The “up”-button and the “down”-button of the directional buttons and the “OK”-button, sitting in between, are used to select a specific one of the alphanumerical characters from the selected group."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"User-interface for entering alphanumerical characters","description":"An information processing system has a display monitor and a user-interface for text entry.
