Finger Touch Interactive Projector Solution
---Laser Image Calibration Technology
Introduction: Finger Touch Projector
Before the Laser Image Calibration Technology, interactive projectors mainly adopt Optical Technology or TI Pointblank Technology, Neither of them can support Finger Touch. After the two-year research and development, we successfully developed an innovative technology: Laser Image Calibration Technology---LICT. This technology has been applied to the short focus projectors and even ultra short focus projectors. When the projector adopts this technology, it will support finger touch and multi-touch. No need electronic whiteboard, users can use finger or any non-transparent objects to control the computer, writing, making note and all the operation as normal interactive whiteboards.
*How it works
The modules come in two parts: emitter and sensor. Emitter can be attached on any flat surface like wall, Board, etc. It emits infrared laser on the projection surface which is about 1mm thick and parallel with the projection screen, 1-2mm above from the screen. when the fingers or any non-transparent objects touch this virtual surface, the light will be reflected and detected by the sensor at the top. Computer will figure out the position of the mouse by high accurate calculation of light position.
Key Features:
1. Finger Touch and Portable: any other product cant both features
2. Automatic Calibration: any solid Interactive Whiteboard cannot support.
3. Remote Control: any solid Interactive Whiteboard cannot support.

Market Prospect
More and more projectors have been equipped with interactive functions, but all of them have to work with the infrared pen. In terms of users’ experience or interactive functions, they cannot beat the ordinary interactive whiteboard with finger touch. As more and more manufacturers begin to produce the interactive projector, the projector’s interactive function is no longer a bright spot and the projector’s competition is hot. If the manufacturer can integrate the finger touch function into the projector, it will undoubtedly increase the competition and raise the company’s popularity and avoid vicious competition of similar products.
Installation case
Finger Touch Module includes 2 parts: image sensor and emitter. Image sensor can be integrated in the projector (the image sensor can be made to order as requirements), the emitter can be mounted on any flat surface. As the following pictures:

Features
4. Support Remote Control:use the wireless laser pen instead of mouse to achieve remote control from away, the pen can achieve the function of left or right click.

About us
EASI (Shanghai) Computer Technology Co., Ltd is a technology company and we specialize in Image Analyzing research and products are mainly sold to Educational market. Using the core technology of interactive module---IR Laser Touch, the normal projector would be transformed into Interactive Projector and instead of traditional whiteboard. Besides, we developed 3D Touch SP1O to transform the existing normal projectors and have interactive function.
In addition, based on Image Analyzing Technology, we developed Automatic Lecture Capturing System in 2006 and it is widely used in Education industry. This product can automatically record the teaching process without any manual operation (camera automatically tracking to shoot teacher and the speaking student).
Enterprise goals: to promote the application of Image Analyzing Technology, promote intelligent education, and build a smart planet.
Service concept: to provide clients with stable performance, technologically advanced products and attentive service.
Development philosophy: Support on the growth of staff and partners to achieve our own development.
Management philosophy: to improve the management system and standardize business processes to achieve long-term sustainable development.
Product and market positioning:
1. Focus on the study of Image Analyzing Technology and accumulate technology to develop at least an innovative product each year.
2. Continue technology innovation, product innovation and the innovation of the application model.
3. Develop suitable products for selling in the global market.
