Using Mobile Phones to Spontaneously Authenticate and Interact with Multi-Touch Surfaces

摘要: The development of FTIR (Frustrated Total Internal Reflection) technology has enabled the construction large-scale, low-cost, multi-touch displays. These displays—capable sensing fingers, hands, and whole arms—have great potential for exploring complex data in a natural manner easily scale size number simultaneous users. In this context, access security problems arise if larger team operates surface with different rights. members might have levels authority or specific roles, which determines what functions they are allowed to via surface. paper we present first concepts strategies use mobile phone spontaneously authenticate interact sub-regions large-scale wall.
