Are Kindergarten Children Ready for Indirect Drag Interactions?

Several studies have shown the suitability of the direct manipulation style and the multi-touch technology for kindergarteners and, as a result, direct dragging has been established as the standard way of interaction when supporting drag manipulations for them. However, there are scenarios in which direct dragging is not appropriate. For example, when the object to be dragged has to move at a fixed speed or performing an animation independent of the actual direct movement speed or trajectory of the user's hand. However, nobody has yet explored the suitability of indirect dragging interaction mechanisms that allow designers to effectively implement these scenarios. This paper evaluates different mechanisms of indirect dragging manipulations (Tap-based, Accelerometer-based and Buttons-based) in order to identify those that could be used by kindergarteners in scenarios where the direct dragging is not suitable. The results show that even though kindergarten children are able to effectively use different types of indirect dragging techniques, some considerations in terms of completion time and precision must be taken into account.
