Abstract
Smart elderly care becomes a popular technology to remotely assist the aged at home in recent years because of the population ageing. This paper demonstrates the DTMF-based realization of IoT remote control for telecommunication operators to achieve the smart elderly-care service. By utilizing IoTtalk, we implement a system, DTMFTalk, which supports IoT remote control via conventional circuit-switched DTMF signaling during a phone call conversation. DTMFTalk can monitor the Call State of the smart phone, capture DTMF keys from the in progress call, and send the key values to the IoTtalk server. Afterwards, the smart elderly-care devices can gain the related IoT instructions from the IoTtalk server. Through the delay measurement experiment for DTMFTalk, we observe that DTMFTalk can constantly and accurately recognize the DTMF keys as long as the user holds the desired DTMF keys with enough period.
