Patent ID: 8564574

Claim:
An input apparatus with multi-mode switching function, comprising: a body for holding; an arc surface touching module, arranged on surface of said body and fully surrounding a side surface of said body, capable of detecting two-dimensional position data via at least one contact; and a control module, coupled to said body, capable of switching said input apparatus to a first input mode based on said two-dimensional position data, and generating a control signal based on said first input mode and said two-dimensional position data, wherein said arc surface touching module provides a continuous touching surface, which can be bent and conform to a surface of said body held by hand and said input mode can be automatically launched and further at least an operation command can be input, wherein said surface of said body held by hand has a circular symmetric surface with respect to a longitudinal central line of said body, and said arc surface touching module is disposed on said circular symmetric surface, wherein a holding pattern of a user's hand remains without change when said body is under rotation shift with respect to said longitudinal central line.
