1. An input device comprising:
- a flexible hinge having an axis, a connection portion, and communication contacts, the connection portion configured to form a physical coupling to a side of a computing device sufficient to secure the input device to the computing device using a plurality of magnetic coupling devices spaced along the axis that do not support a communicative coupling with the computing device, the communication contacts spaced along the axis and configured to form a communicative coupling between the computing device and the input device; and
an input portion having a writing surface configured to perform a change in optical states that is viewable by the user, the change in the optical states performable without use of electronic computation, the writing surface comprising a protective surface, one or more sensors, and a display state change material disposed directly between the protective surface and the one or more sensors.

Abstract
Input device writing surface techniques are described. In one or more implementations, an input device includes a connection portion configured to form a communicative and physical coupling to a computing device sufficient to secure the input device to the computing device. The input device also includes an input portion having a writing surface configured to perform a change in optical states that is viewable by the user, the change in the optical states performable without use of electronic computation.

14. A system comprising:
-
a computing device having a display device that supports touch functionality sufficient to detect one or more gestures and a first side generally perpendicular to the display device that defines an axis; and an input device having a second side, the second side removably coupled physically to the first side of the computing device along the axis, the input device having a writing surface configured to perform a change in optical states that is viewable by the user, the change in the optical states performable without consuming electricity, the writing surface comprising a protective surface, one or more sensors, and a display state change material disposed directly between the protective surface and the one or more sensors, the input device further having a connection portion along the second side having a plurality of magnetic coupling devices that are spaced along the axis. - View Dependent Claims (15, 16, 20)

17. An apparatus comprising:
-
an input device flexibly connected to a connection portion, the connection portion having a plurality of magnetic coupling devices spaced apart along an axis and configured to form a magnetic coupling to a computing device, the magnetic coupling sufficient to secure the input device to the computing device; and an input portion having a writing surface comprising a protective surface, a pressure sensing digitizing pad, and a display state change material disposed directly between the protective surface and the pressure sensing digitizing pad, the writing surface configured to; perform a change in optical states that is viewable by the user, the change in the optical states performable by the display state change material responsive to application of mechanical pressure by a stylus; and communicate data describing the application of the mechanical pressure via the connection portion to the computing device, the data output by one or more sensors of the pressure sensing digitizing pad that is configured from a plurality of membrane switches disposed on an opposing side of the display state change material with respect to a side that received the application of the mechanical pressure. - View Dependent Claims (18, 19)
