We reconstructed a model based on the unified theory of acceptance and use of technology to analyze the acceptance of intelligent vital monitoring products (IVMPs) by middle-aged people. Results revealed that the dimensions of performance expectancy, social influence, and facilitating condition all positively influenced the intentions of middle-aged people to use IVMPs. Our results may be of use for telehomecare health services when designing and developing IVMPs for people of all ages in the future.
