This blog is to serve as a working experiment of the ideas listed below.
To further advance this field of technology, SwiftLife Inc. is dispensing its design details freely to the public.
SwiftLife Inc.
Project: Multi-Touch
———–
Purpose - Allow for a cheap and inexpensive multi-touch solution.
Use on computer screens, touch tables, touch walls or any other invisible control plane.
Method - The device will need the ability to read out coordinates on a rectangular or square plane. Using point(s) of reference to find the exact pixel position.
Analysis - A optic system that can detect measurement of distance. i.e. “Beam Break Technology”. This system will be used in order to gain the coordinates by measuring the optic distance of one or two beams. The optic system will consist of an invisible low level laser. Project can be singular and small in size. Wireless Bluetooth operation and battery system. This device may be used for many applications.
Technical - The measurements will be taken using a curved math algorithm to determine the proper coordinates. These will be done by two optic devices. The device can be built in to existing, new or recycled monitors or table top device. The measurement of distance will be taken from two optic devices giving the curved plotted point as seen below. This is the key aspect to the design.

Break Down
1. Optic signal is sent out on a 90 degree arced plane.
2. Measurements are taken from each of the multi-touch devices.
3. These measurements are then calculated giving the screen position.

Distance measurements read out calculating the plotted point. As the pointer moves within the Optic grid, each of the two multi-touch devices read out separate measurements.

Measurements can be calibrated to give exact screen coordinates, controlling a USB pointing device feature. The device optic power will be provided by USB power.
The device will send out an invisible optic signal rotating at a 90 degree angle. Each device will be positioned at the two top, bottom or side corners.
The optics will need to calculate distance from the break point and the position of angle into code. The distance beam will be computed along with the other distance measurements for coordinates.
Computer use of this device is almost unlimited; software drivers will pass coordinates through resolution ratio providing the coordinates. Future models can use Radio/Bluetooth technology along with USB for laptops, projectors, console games and for ease.
The device will be able to work on any size platform depending on two key aspects.
1. The optic power of the devices
2. The distance between the devices
In the design on two multi-touch devices there can be either two operating or one dummy. The dummy module would contain a mirror to refract the optic signal.
There would also be a small tube hole with a sensor in the back at the center point of the device. This will allow us to send a optic signal to provide a straight path to hit the sensor, leveling and reading us the devices distance apart.
*Design can be completed with split beam with mirrors, whereas only one of the two devices needs to be powered. Or a scanning beam optic with a single beam covering the distanced of the 90 degree arced plane.
Universal Level/Calibration – The design is universal as in the distance calculator from one device to the other will calculate the center point of the device. It will then read out a distance measurement of the space between the devices. This measurement can be computed to find the exact dimensions of the plane. This allows us to adjust a correct pixel ratio to the device.
The device will have a small LED light to confirm.
The device may also have small turn able screws with a sticky tape to be attached. The screws can be slightly turned to increase level and balance.
The device can also have a optional calibration software. Pressing the corners of your screen to correct any calibration issues.
Optics
Using a straight single laser beam quickly spread along the 90 degree arc. Any break will report the dependent distance to the device.
Possible Applications:
This idea has the ability to create and applications; in a touch screen computer; in a touch wall; in a touch table; in a invisible touch area, in a robotic sensor; in a space detection grid; etc.
