One of the best combinations with pen, we consider audio recorder. For example, Livescribe can link the point in the handwriting with the audio record and then play it with tapping to that point.

See comparison table:

Some vendors provide handwriting recognition (OCR) software or you can buy third-party software for about $30. But even the best result cannot beat 93% threshold.
Some other vendors not listed in the table are: Adapx, Epos

Livescribe has the greatest additional functionality: audio recording with embedded microphone, headphones jack for listening that, built-in speaker, 96×18 OLED display and even half a Gb space on community site. But, it requires special paper. It can be bought or printed but anyway it looses portability of a little pen with the need to carry a sketchbook.

Every dotted sheet of paper is unique because it has its own printed digital signature. With ‘any paper’ pen changing of sheets is performed with mounting receiver by a clip on a new sheet. The drawback of any device is a newline: every line on the notepad becomes a separate line in the electronic document, and you can’t make corrections as you write. Dotted paper technology is limited to percent of filling with ink. Filled area can’t be recognized by camera for positioning. So, the artist wouldn’t be able to draw a painting.

Logipen uses ultrasonic technology for coordinates positioning. Tip of the pen whistles with ultrasonic sound and receiver listens to it with two mics thus calculating relative position of the pen. It is the best ‘standalone’ alternative to the previous competitor. Wacom tablets are prevalent among designers because they have really impressive touch force sensitivity.

Using with mobile phone

Having such handy portable digital input device it would be nice to have a screen to watch result on. Of course, it would be a mobile phone. It can be a great variety of applications for using them together:

1. Filling up forms in institutions (watch video)

There are already several companies that provide business solutions utilizing digital pen technology.

2. Make sms live. It is nice to add handwritten smile or draw a map scheme, diagram to the message. And its even faster to use a pen instead of a mobile phone keyboard.

3. Share notes just made on paper with remote people

Ideas for the new concept

This review with links provided shows already developed functionality for the digital pen. Now, we are going to create fresh new ideas to consider implementing in future models.

Facts – At the beginning some information was presented to the audience
- The pen should comply universal standards: weight, length, form.
- wi-fi detector
-  digital pen (watch video)
- Patent for digital pen using accelerometers and gyroscopes

Emotions
- fatigue in hand
- hate pens which can be easily broken
- metal is nice by touch
- dislike smell of iron, if the surface is not nickel-plated
- the hand of left-handler is soiled
- heavy – light
- pen cannot be erased as against pencil
- like to twist in hand
- nicely designed
- branded
- expensive
- can’t make undertint

Creativity
- text highlight while writing
- pointer
- transformer
- save the writing in the vector image format into embedded memory
- wireless transfer writing to the laptop
- pens movement corrections (calligraphy correction)
- autocomplete
- warm pen
- charging from usb
- charging from hand heat
- charging while jolting
- mobile phone with voice commands
- mp3
- one string display (running letters) – display is hidden by the shield. opened by cap twist
- gyroscopic pen?
- feed the ink by sensor command. Sensor is located on the tip of the pen
- erasing ink
- use of saved writing by digital pen:
* order of writing words and letters facilitates handwriting recognition
* editing (with original paper)
* Pict bridge instant printing (without computer connection)

Positive
- gadgets are popular
- with electronic pen you can use any surface, as against tablets
- saving notes is much faster than any communicator can do
- the smallest device for taking digital notes

Negative
- it should be cheap to be widely sold
- tablet-PC or any sensor display with a stick is the same as digital pen with PC. Unlike the latter, former already exists on the market.
- keyboard is much faster input device than a pen
- keyboard input is much less erratic than recognized handwriting

Tasks to develop

- Investigate on application of perspective ideas
- Allocate realistic ideas and look for analogue
- Perform innovation solution for reasonable ideas if there would be any.

Advantages:
You can buy any amount of food. Even if you want to taste a small cup of beveradge with handful of favorite chocolate nuts.

I think people would rather prefer these machines to regular stands and shops. Of course obligatory requirement is freshness of products, so consumers can get used to high quality service and thus gains confidence. Perhaps, it should be non perishable products.

Nowadays there is plenty of packed food for sale.In Italy there is a pizza vending machine which whips flour, water, tomato sauce, and other ingredients to create the fresh pizza within 3 minutes. The starting price of a pizza made by the vending machine is about $4.50
