A wearable, portable keyboard is implemented as a vertically modified keyboard which is strapped onto a person's thigh as shown in FIG.2. This keyboard is an accessory for entering text and data into a cell phone, a PDA (Personal Digital Assistant) or a portable computer. This innovative keyboard is operated by one hand. Nonetheless, it has all the standard keys of a conventional keyboard. It is also designed with our finger sizes in mind. Therefore, instead of operating a PDA or cell phone with our thumbs, when we are moving around, on a bus, on a train, or sitting on a bench at a park, we use our PDAs or cell phones to monitor what we punch on the keyboard attached to other thigh with our free hand. Furthermore, these keyboards may be worn under the clothing or on the clothing. They could be made transparent made of durable nylons or polymers, or they can be made of other water proof light fabrics. A cable may be used to send the stream of text or data to a cell phone or a PDA via USB or serial port (e.g. RS-232). More conveniently, the keyboard can send data to the devices wirelessly using already available technologies such as the Blue-Tooth or a radio frequency (RF) transceiver. But attention must be made to the security of the data on the later case, for example the data must be coded randomly for each individual keyboard made which may be hard coded in the keyboard circuitry or can be changed as frequent as need by the owners of the keyboards.
