Abstract: The present invention provides a handheld sweeping and mopping structure, comprising a handle and a body shell, wherein a sweeping and mopping module, a water tank module, a driving module, a garbage collection module, a control module and a power supply module are provided inside the body shell. The handheld sweeping and mopping structure of the present invention can sweep the floor and also mop the floor, has higher efficiency and better effect than the conventional sweeping and mopping mode; and meanwhile, a disposable garbage box which is convenient to replace is used, and it is unnecessary to clean the garbage box repeatedly.

Abstract: An input device has four control points corresponding to four fingers of a human hand. The first three control points provide means to traverse a ternary tree. Each node of the ternary tree contains a set of 27 related characters. The fourth control point provides means to enter the chosen node, and the input device uses the corresponding character set. The character set is divided into three subgroups, and the user can use one of the first three control points to choose one group. The divide-and-choose process continues until the desired character is unambiguously chosen. Then the process starts again from the complete 27 characters. The fourth control point provides means to switch among character sets and escape into the ternary tree navigation mode. Furthermore, each control point is associated with a musical note.
