"When a respective view includes user interface objects of different sizes and/or shapes (or child views of different sizes and/or shapes), there are multiple ways to identify a user interface object that is closest to a contact. In some embodiments, a centroid-to-centroid distance, which is a distance from a centroid (e.g., 409-1) of a contact (e.g., 409) to a centroid of a user interface object, is used to determine a closest user interface object. In some embodiments, a shortest distance, which is a distance from a first point on a user interface object that is closest to the centroid (e.g., 409-1) of the contact (e.g., 409) is used. "

各ビューが異なるサイズ及び形状の少なくとも一方のユーザインタフェースオブジェクト（あるいは、異なるサイズ及び形状の少なくも一方の子ビュー）を含んでいる場合、接触に最も近いユーザインタフェースオブジェクトを識別する方法が複数存在する。いくつかの実施形態では、重心間距離、これは、接触（例えば、４０９）の重心（例えば、４０９−１）からユーザインタフェースオブジェクトの重心までの距離であり、最近接のユーザインタフェースオブジェクトを判定するために使用される。いくつかの実施形態では、最短距離、接触（例えば、４０９）の重心（４０９−１）に最も近いユーザインタフェースオブジェクト上の第１の地点からの距離であり、が使用される。

"In addition each atom data entity will broadcast its ‘I am here’ message to all other atom data entities. An atom data entity is aware of its own position, so it can calculate the distance to other atom data entities from the ‘I am here’ messages it receives. If an atom data entity that it is repulsed by is within the set tolerance level then a repulsion force acts. The repulsion force is proportional to 1/d where d is the calculated distance between the centers of gravity of the two atom data entities. The repulsion acts along the line which connects the centers of gravity of the two atom data entities."
