Abstract
Touch is one of the most important human senses. With the popularization of touch-screen mobile phones, tablet computers, and other devices, touch-screen interactive technology has become a norm in people’s daily lives, and advertisements that were once dominated by vision and hearing have added an interactive experience in the dimension of touch. Traditional advertising media screens can only complete simple information dissemination functions and cannot interact with users in a two-way manner. They can only receive information one-way and passively and lack interactivity. Touch-screen interactive advertising forms a good interaction with the target audience, thereby disseminating advertising information to achieve the purpose of promotion or brand image building. This paper designs a set of advertising media screen interaction systems based on smart sensors, including a gesture interaction module, a remote interaction module, and a touch interaction module. The gesture interaction module can recognize 5 static gestures and send gesture commands to control the advertising media screen. The remote interaction module can remotely control the advertising media screen, and the touch interaction module can control the advertising media screen through the touch screen. According to the functional requirements, the overall design of software and hardware is given, and the technical background of each module of the software is introduced. Next, the depth image-based gesture recognition method is studied. The number of fingers and the center distance feature are fused as feature vectors, and the weighted template matching method is used to classify and recognize gestures. Finally, the design and implementation of the interactive system are introduced.
Highlights
Erefore, human beings have an innate trust in tactile cognition, and tactile sensation is more realistic than any sensation [1–4]. e machine originally invented by mankind mainly uses vision and hearing for human-computer interaction
Advertisers design advertising information into the interactive link, and advertising audiences use touch screens to interact with people and receive advertising information during the process of participation
Ese can be called “touch-screen interactive advertising.” [17–21] e media in touch-screen interactive advertising is a “touch-screen” type of media, the experience mode is “interactive,” and advertising is its goal. e purpose of touch-screen interactive advertising is to form a good interaction with the target audience, thereby disseminating advertising information to achieve the purpose of promotion or brand image building [22–24]
Summary
As a means of interaction that conforms to a human’s daily interaction habits, is simple, direct, and natural. e research and application of gestures has attracted great attention from researchers at home and abroad. E idea of mean filtering is to first use the EPC660 TOF camera to shoot multiple consecutive depth image sequences, randomly select a certain number of images from the shooting sequence, and sum the depth value of each pixel to find the average value to reduce noise. When the measured object is in a moving state, if the average filter is used, the image will be blurred because the pixels at the same point in different images are parallel. When the application scenario requires high real-time performance, using the method of mean filtering is not applicable; when the number of selected images is more or less, it will affect the filtering effect
