A method of manufacturing a hidden type shoe with a replaceable vamp mainly includes a plurality of seal elements disposed in advance on a lower side of an upper mold of the shoe. The dual opposing peeling blades are relatively widely spaced apart at approximately {fraction } to allow the peeling element to cut through the tough, thick skins of a green banana or plantain. A controller controls the vertical arraying device, the vacuum absorbing device, the guiding and pressing device, and the first and second loaders to mount the plurality of spacers on the panel. The vertical signal lines extend along the columns of unit cells, respectively, each for receiving a electric data item corresponding to the electric charge accumulated in the charge-accumulating section of any unit cell of the associated column. The deceleration characteristic can be predefined or can be selected from an array of deceleration characteristics in dependency on an operating behavior of an accelerator pedal. In some variations, the control takes the shape of a compass rose with at least two opposite axes, the activation of which cause the information displayed within the software application to become coarser or more granular depending on which of the two axes is selected.
