Abstract

DETECÇÃO DE BARREIRA PARA AUXILIAR RASTREAMENTO DE CONTATO. Técnicas são fornecidas para utilizar dispositivos sem fio para rastreamento de contato, e mais especificamente para detectar uma barreira entre dispositivos para aprimorar os aplicativos de rastreamento de contato. Um método de exemplo para detectar uma barreira entre um primeiro dispositivo e um segundo dispositivo inclui determinar, pelo primeiro dispositivo, uma primeira medição de alcance em relação ao segundo dispositivo usando uma primeira técnica de posicionamento determinando, pelo primeiro dispositivo, uma segunda medição de alcance em relação ao segundo dispositivo usando uma segunda técnica de posicionamento que é diferente da primeira técnica de posicionamento, e detectando a barreira entre o primeiro dispositivo e o segundo dispositivo com base na primeira medição de alcance e na segunda medição de alcance.
