Object Manipulation by Absolute Pointing with a Smartphone Orientation

The purpose of this study is to operate various computers around us using our own smartphones. A large number of Internet of Things (IoT) devices are now widespread. Thus, we need a method that can operate many computers seamlessly. The operating method by voice can operate computers seamlessly and the method is being popular. 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 by a smartphone orientation. The orientation can be measured with standard sensors that a general smartphone has. This method achieves controller integration, multiple functions, and simultaneous use by multiple people.
