 The chapter begins with a familiar button that we can picture it in our head, something like switching on/off a light, a kettle and many other electronic devices. A button is "seductive" (ref: pold p. 34), indicating a potentiality of interaction and generating a desire to press it, and usually it comes with an immediate feedback. Similarly in software and platforms like Facebook, a button indicates a call for actions, inviting a user to click and and interact with it in a binary state: on or off, like or (not)like, accept or cancel. Further with the capability to customize wordings on a button, Pold suggests that a button is developed with distinct functionality and signification (ref: pold p. 31).

Then it will further discuss different modes of capture in contemporary culture.
