Mobile interaction is the study of interaction between mobile users and computers. Mobile interaction is an aspect of human computer interaction that emerged when computers became small enough to enable mobile usage around 1990 s. Goals Mobile devices , in particular, mobile phone s, PDA s and mobile Digital audio player music player are an essential part of life for billion users. The goal of mobile interaction researchers is to understand the requirements and needs of mobile users. Compared with stationary devices mobile devices have specific, often restricted, input and output requirements. A goal that is often named is to overcome the limitations of mobile devices. However, exploiting the special opportunities of mobile usage can also be seen as a central goal. History One of the first work in the mobile interaction discipline was the concept of the Dynabook by Alan Kay in 1968. However, at that time the necessary hardware to build such system was not available. When the first laptop s were built in the early 1980th they were seen as transportable desktop computers. Mobile interaction became more important when mobile phones and PDAs became more common. In 1998 Chris Johnson organized the first workshop on MobileHCI human computer interaction with mobile devices which focussed on mobile interaction.

Unreferenced date December 2009 In physics , interaction energy is the contribution to the total energy that is caused by an interaction between the objects being considered. The interaction energy usually depends on the relative position of the objects. For example, math Q 1 Q 2 4 pi epsilon 0 Delta r math is the electrostatics electrostatic interaction energy between two objects with charges math Q 1 math , math Q 2 math . Supermolecular interaction energy A straightforward approach for evaluating the interaction energy is to calculate the difference between the energies of isolated objects and their assembly. In the case of two objects, A and B , the interaction energy can be written as math Delta E int E A,B left E A E B right math , where math E A math and math E B math are the energies of the isolated objects monomers , and math E A,B math the energy of their interacting assembly dimer . For larger system, consisting of N objects, this procedure can be generalized to provide a total many body interaction energy math Delta E int E A 1 , A 2 , .., A N sum i 1 N E A i math . By calculating the energies for monomers, dimers, trimers, etc., in an N object system, a complete set of two , three , and up to N body interaction energies can be derived. The supermolecular approach has an important disadvantage in that the final interaction energy is usually much smaller than the total energies from which it is calculated, and therefore contains a much larger relative uncertainty. In the case where energies are derived from quantum chemical calculations using finite atom centered basis functions, basis set superposition error basis set superposition errors can also contribute some degree of artificial stabilisation.

Unreferenced date October 2009 In particle physics , an interaction point IP is the place where particles collide. One differentiates between the nominal IP, which is the design position of the IP, and the real or physics IP, which is the position where the particles actually collide. The real IP is the primary vertex of the particle collision. For fixed target experiments, the IP is the point where beam and target interact. For colliders and collider experiments , it is the place where the beams interact. Experiments particle detector s at particle accelerator s are built around the nominal IPs of the accelerators. Therefore the whole region around the IP the experimental hall is called an interaction region.
