 We evaluated the users' ability to control the bending of FlexStylus, and compared it to pressure input~\cite{fellion17}.
 We found out that the participants of our studies were more precise with the flexible pen than with pressure input.
-Pressure pens are isometric devices, therefore it is unsurprising that they do not perform well with position control~\cite{zhai93,zhai93a}.
+Pressure pens are isometric devices therefore it is unsurprising that they do not perform well with position control~\cite{zhai93,zhai93a}.
 Flexstylus can be considered as an elastic device.
 Therefore position control can be an issue.
-However, the classification of an flexible pen between an isotonic or elastic device essentially depends on it flexural stiffness.
+However, the classification of a flexible pen between an isotonic or elastic device essentially depends on its flexural stiffness.
 A soft flexible pen is most likely to behave like an isotonic device while a hard one should act like an elastic or even isometric device.
 Therefore with the next generation of flexible styluses, HyperBrush, we wanted to compare different flexural stiffnesses.
 
 We built several prototypes of different flexural stiffness (\reffig{fig:flexuralstiffnesses}).
-The thickness is ajusted with the thickness of the flexible parts inner walls.

 The measure of flexural stiffness we used is the ratio of amount of force applied per unit of deflection.
 We measured it with a hollowed cylinder cantilever beam test.

 We compared the performance and subjective preferences between these different flexural stiffnesses and a pressure pen for pie-menu item selection and for brush stroke precision.
-The results does no show any clear better configuration.
-This suggest that the best is to provide users several interactive pens that provide different kinds of input vocabularies and haptic feedback.
