A system for determining a touch point's location within a user-definable region is provided. The system comprises plural modules. In a set-up stage, a user positions each module to define a peripheral point of the region. Exemplarily, a module comprises a means for detecting alignment between the module and another one, a means for measuring an inter-module distance, and a means for making wireless data communication. In particular, the detecting of the alignment and the measuring of the inter-module distance are configured to be performed without physically connect the two modules together. Hence, a geometric coordinate of the module relative to the other one is determinable without a need to physically connect the two modules. The system can thereby be compactly packed for traveling to give an advantage of high portability to a portable interactive whiteboard system that incorporates such system.

A packaging device for continuously forming and filling a package having a plurality of separate sealed cavities comprises a plastic film winding barrel, a vacuum cavity forming device, a filling means, an aluminum foil winding barrel, a pressing sealing means, and a cutting machine. The vacuum cavity forming device causes the plastic film to be formed with a plurality of cavities. The filling means pumps liquid material into each of the cavities holes. Aluminum foil is adhered to the strip plastic casing by a pressing sealing means. Finally, the cutting machine serves to the cut the strip casing to complete a packaging process.
