Abstract: An input module includes a substrate, at least two bio-keys and a control unit. The substrate has at least two bio-leads and switches. Each of the bio-keys has a key surface, at least one conductive elastic piece and a protrusion. The conductive elastic piece is electrically connected and conducted to the key surface and the bio-leads. The control unit has an input-signal generating element and a biological-signal generating element. The input-signal generating element is configured to generate a first input signal and a second input signal by using the protrusion to toggle the switch. The biological-signal generating element is configured to generate a bioelectric signal through the electrical conduction between the bio-key and the bio-lead. The present invention further provides an electronic device, in which the bioelectric signal is analyzed by an operational unit to generate a biological function index.

Abstract: A method for determining the number of fingers on a sensing device, which has a plurality of scanlines, includes the steps of: identifying the scanlines that generate a detecting signal, which has a value greater than a threshold value; finding adjacent ones of the scanlines; forming at least one group from the adjacent ones of the scanlines thus found; and counting the number of the scanlines in the at least one group thus formed in order to determine the number of fingers on the sensing device.

Abstract: A touch sensing method includes: scanning a plurality of first and second sensor lines, aligned in two different directions, of a touch sensor board; generating first and second indications based on the scan result, the first/second indication carrying information of at least one group of the first/second sensor lines that are adjacent to one another on the touch sensor board and that have detected a user's touch on the touch sensor board and of a number of the first/second sensor lines in the group; and generating a status signal that corresponds to a predetermined finger gesture at least based on a comparison result determined by comparing the number of the first sensor lines indicated by the first indication with the number of the second sensor lines indicated by the second indication. An electronic device that implements the touch sensing method is also disclosed.

Abstract: An input device includes a contact sensing surface having at least one key region and a controller. The controller includes: a position-detecting unit configured to detect the position on the contact sensing surface contacted by an object, a memory unit configured to store at least one functional data each corresponding to a key function, a key-triggering unit configured to read out the functional data in the memory unit and activate the corresponding key function without a sliding into the key region, a key function setting unit configured to change the functional data based on the direction and distance of the object sliding within the key region. With this arrangement, the key function setting unit can reduce the number of the keys regions virtually provided on the contact sensing surface, thereby providing an intuitive operation of key functions for a user.
