  Using high spatial and temporal resolution H$\alpha$ data from the New Vacuum
Solar Telescope (NVST) and simultaneous observations from the Solar Dynamics
Observatory (SDO), we present a rare event on the interaction between two
filaments (F1 and F2) in AR 11967 on 2014 January 31. The adjacent two
filaments were almost perpendicular to each other. Their interaction was driven
by the movement of F1 and started when the two filaments collided with each
other. During the interaction, the threads of F1 continuously slipped from the
northeast to the southwest, accompanied by the brightenings at the junction of
two filaments and the northeast footpoint of F2. Part of F1 and the main body
of F2 became invisible in H$\alpha$ wavelength due to the heating and the
motion of F2. At the same time, bright material initiated from the junction of
two filaments were observed to move along F1. The magnetic connectivities of F1
were found to be changed after their interaction. These observations suggest
that magnetic reconnection was involved in the interaction of two filaments and
resulted in the eruption of one filament.
