Gesture Android Tablet - Tweak and Squeeze

I was forced to Invent again, this time it is a Gesture Tablet. Tweak and Squeeze the Air above Tablet. 3D input device for Android Tablets. - 2011

A Tablet built with four embedded but slightly tilted cameras in the four corners and a dedicated ARM Input processor. This detects and interprets the 'finger gestures' to enhance the touch experience and also Sketch/Write with dummy stylus/brush.

Texas Instruments Embedded Processors Wiki

The software is as complex as speech recognition. For Factory Workers, Thick Skinned or Burly Hands you could totally switch to Gesture Mode.

Gesture Tablet.

Even if the Tablet Sports the Gorilla Glass, a Gorilla cannot use it with a Touch Interface, no not even a Chimpanzee. So Gesture Interface in very important for Larger 10 inch tablets. Makes Text input a Breeze and Boosts Gaming and 3D Capabilities.

How would you like to Make a Painting by just a gentle Swish and Swoosh of a Paintbrush over the Tablet. Even Drum your favorite tune by beating the Air on the Top of the Tablet.

Then you could create a 3D Sculpture on a Virtual Plaster of Paris block. You just need to download the right App, chisel and chip away the Air on the Tablet. When done, print to the 3D Cloud Printer Provider, a few hours later you collect the 4 numbers of 3D Prototype Prints from the Courier Man.

Let us take the Carrom Game as a Usability or Ergonomics Experiment, this game will be very effective only with a Gesture Tablet.

I got this idea after writing this feedback related to Touch Interface......

Butter Fingers and Ironman Thumb Issues

Not all Men/Women/Neumen are alike. Some have movements with less control and others like Hands-on Miners or Blacksmiths have fingers with a layer of Tough Corny Coat to protect it.

We need 'Touch Gloves' or 'Touch Thimble'. These will empower even Ironman and 'The Hulk' to use a Tablet, Then only a Military Grade Space Ruggedized Version will do.

Bot as SMD Soldering Aid

I need a Bot to help me with soldering. Years of looking at Monitors and Double Clicking Mouse, have taken their toll .

Please develop a Camera/Monitor assisted Soldering/Desoldering Workstation. The Miniature Soldering iron manipulated by a Joystick into position and then press the fire button, a tiny blob of solder paste lands on the Junction on Focus. Now press the fire again, a Perfect Shiny Soldered Joint.

2016  - There is a solution from Martin that is close to what i had in mind.

The Expert 10.6 rework stations facilitates the reliable and precise rework of BGA-, CSP-, and QFN-components, connectors and sockets. Innovative technologies

Rework Station EXPERT 10.6

What we need is a Desktop Aid for SMD prototype fabrication and SMD Card Repairs. Not for manufacturing. To be used by Design Centers and Service Centers.

The card to be populated or repaired can be moved in X-Y-Z axis using  a PC. The Soldering Tool and the adhesive and paste dispensing tool should sync with the PCB Position. Then Soldering and Desoldering should be automated by the machine with camera, after Package type is keyed in. It is a Hands Free Soldering machine with the PC Monitor and HD Camera helping the visualization of the Job

Programming Breakpoints and Testpoints

Breakpoints may not serve the purpose fully, it may be easier to use Testpoints and incremental coding.

When we build Electronic Circuits with many Interacting Blocks or Modules, We put a small 5mm Tall Copper Pin in the PCB or a PAD without masking. This is a Test or Troubleshooting Point. This is where you can probe with a scope, dmm or logic analyzer.

Programming Breakpoints and Testpoints

In embedded program development, i tried a similar way, a Testpoint in software, but only that the card would light a led in a certain pattern or send a "all ok" and progress status to the serial port connected to PC.
In Script programming we can use a GUI element, just a Textbox as a Scope monitoring the Testpoint. When the program goes beyond the Testpoint, The GUI Text window will hold the Status. Just like you move the probes of the same DMM, you can keep shifting the Testpoints or Multiplex the same Scope, as the program becomes bigger.

So, before you build the Next big Program, Build the Test Equipment and the First Testpoint. The first few lines of code is written around the First Test point. Like it is done in PCBs, incremental Building-Testing.
Lastly Break Big Jobs to Small Pieces. Like the Plugin Modules in a Oscilloscope, The Components or Modules should be built and tested independently and then Combined to Form one Big System. Then they can be maintained and reused easily.
