Gestural interactions are being deployed increasingly, in human-computer interaction, in an attempt to create more natural interfacing with the plethora of new digital environments. If these new applications are to successfully enter into use, in our day-to-day lives, their development must be underpinned in equal measure, by robust and intuitive interfacing methods. This research implementation looks at two-handed spatial gestures and moots the question that seeks to inherit the merits of isotonic gesture recognition on touch screens, in physical space.

The advantage of evolving unique gesture sets, from 2D isotonic interactions is that there exists the real possibility that the new styles will be easy to learn and intuitive to use. This research explores this possibility by building a prototype that responds to two handed gestures sets. The underling purpose is to construct manipulation styles to transform computer graphics. These styles are comprised of unique combinations of two-handed gesture inputs, location data and proximity information. To keep the system as intuitive as possible, this implementation draws from the extensive library of information available in two-handed isotonic gesture actions.

The prototype is evaluated in terms of gesture recognition and orientation, while its use is demonstrated with the execution of two object transformations: specifically, move and scale. Users will be tested on how successfully they manipulate the graphics using the prototype's predefined styles.
