A computer is adapted for changing one or more of the application, security, or user contexts based on the orientation of a component, such as a monitor. Changing the context responsive to the reorientation allows two or more users to use the same hardware to complete a transaction requiring at least two perspectives, for example, buyer and seller. In the background, transaction end points may be changed as well as establishment of a secure channel for supporting confidentiality of a user and their personal information. The computer so equipped may be applicable to many situations involving two parties, such as hospitals, personnel/human relations, banking, government benefits, and retail.
