Object Manipulation by Absolute Pointing with a Smartphone Gyro Sensor

The purpose of this study is to operate various computers around us using our own smartphones. Methods for operating computers around the home by voice, such as the Internet of Things (IoT) appliances, are now widespread. However, there are problems with operation by voice; it is limited in terms of instruction patterns that can be expressed, and it cannot be used simultaneously by many users. To solve the problem, we propose a method to determine the location pointed to by a user with a smartphone gyro sensor. This method achieves controller integration, multiple functions, and simultaneous use by multiple people.
