Patent US5356330 allows one of the best forms of greetings to be more effective and accurate for an individual. What the device does is assist a artificial arm and hand to perform the task of a high-five. Breaking it down to its technical components, the device is an apparatus that attaches to the upper part of the artificial arm and the artificial lower arm portion. The elbow joint allows pivoting through a secure spring. Adjustments can be made for the most effective alignment.
The purpose of the device, stated by patent owner Albert Cohen, is to allow lonely people to have something to high-five with when they are alone. This is particularly useful when watching a sports game alone, he noted.
To be honest I have never had the urge to high-five someone when I am alone. The high-five gesture is a social interaction, not something that needs to be simulated. I would not be depressed if I do not have a high-five buddy. I would be more depressed if I owned a device like this.
