Abstract—In this study, a 3D display and interactive laser technology are integrated to develop an interface system with virtual touch and to build up a laser interactive 3D game platform.

Keywords-3D display technology, interactive laser, interactive 3D game platform Introduction

I. INTRODUCTION

Due to the rapid growth of science and technology, video games become more interesting with more diverse interactive models. In displays and games industries, the researches and developments focus on real-time interface interactive system such as control panel, image recognition technology, and so on.

Laser beam is as the control variable within the interactive game platform in this study. A user can control the direction through observing the direction of laser beam during the game because the directivity. The position of spot can be determined via a video capturing. Besides, to compare laser beam with other remote controllers in the market, it is inexpensive and easily obtained.

In order to bring a sense of reality from 3D video that people can enjoy it at home, our study of 3D display technology is integrated with laser interaction interface technology. Expect to develop a 3D laser interactive game platform conducive to the mobility impaired patients.

Furthermore, considering the discomfort from watching 3D video [1, 2], this study does the detection of human factor for the 3D laser interaction platform system to achieve the goal of human care.

II. METHODS

This study focuses on designing and producing a game platform for the mobility impaired patients under the integration of three-dimension and laser interaction technology.

The hardware framework design concept of 3D laser interactive game platform is shown as Figure 1. Using a 3D display for projecting 3D image with basic principles, such as refraction and reflection. Then, 3D image is refracted to human eyes via reflectors. There are some novel effects because of the appearing suspended stereoscopic image while a user is watching it. It is attractive to increase the immersion of games from the combination of background music and sounds. It is shown as Figure 1. The CMOS which capturing the laser spot is placed under the reflector that the plane coordinate position of the above screen can be caught. The cursor can be moved to screen spot's position through computing the interaction of laser spots. The interactive system framework is shown as Figure 2.

The design flow is separated to six steps shown as Figure 3. The descriptions of six steps are as bellows:

Step 1: Select 15 inches auto stereoscopic screen as a game platform display

Step 2: Select integrate laser spot control as the game interactive interface. Green laser is as the control variable in this study.

Step 3: Design a Flash game similar to Star Wars. The background is earth and other planets. The screen appears moving UFOs randomly.

Step 4: Complete the determination of laser spot’s position through filming with a CMOS and computing with a computer.

Step 5: Use laser spot to replace mouse. There are some images and sounds of crushing and crashing while users click the UFOs.

Step 6: After completed the system initially, the physical signals are detected, including Electroencephalography (EEG), Electrocardiography (ECG), Electromyography (EMG). And the survey is evaluated to accomplish the human factor detection evaluation. The results might be sent back to the system to adjust the parameters to establish a suitable safe game platform for the mobility impaired people.

III. RESULTS AND DISCUSSION

Refraction and reflection, the basic optical principles, with determination of laser spot and the detection of human factor build a suitable 3D laser interactive game platform which can be easily used by the mobility impaired patients. It is shown as Figure 4. The whole chamber can be magnify or minify. The content of Flash game can also be changed.

So as to control the game for users during the experiment, we add a filter in front of the camera lens to remove other useless optical wavelength.

Results from detection of human factor, such as EEG, ECG, visual fatigue, are to adjust the specification of stereoscopic display and the depth perception of 3D Flash game image that a human-care game platform can be established.

IV. CONCLUSION

The idea of 3D laser interactive game platform in this study provides the mobility impaired people to remote operate and control 3D video games. The detection of human factor can ensure a user’s health and safe situation to build a high quality game platform. For the purpose of bringing benefit more mobility impaired patients, it can add to other interactive function such as voice control, EGO control, BCI, and so on. The expectation is to make it closer to humanity assistive technology.
