NaiBoli is a new gesture language being developed to provide a comprehensive notation for gesture modeling that is independent of device, platform, programming language, and natural language. It divides gestures into base elements, tools used, actions, transformations, and resultant gestures. The language is intended to be easy to learn and use, and evolvable as gesture recognition technology advances. This document outlines the initial version of the NaiBoli language elements in each category.

1. Comprehensive gesture language – NaiBoli v 0.1
While conceptualizing a mobile app, I realized there is not a single comprehensive notation for
gesture modeling. There are few attempts which seem to be incomplete. So as usual, I have to
develop my own solution.
Before diving further, I like to call gesture language a name - NaiBoli.
Nai – नई (New)
Boli – बोल (Dialect)
While designing NaiBoli following factors were of prime concern:
1. Should be independent of device, platform, form factor, programming language, and
natural language.
2. Should be easy to learn and use (manually as well as tool)
3. Gesture recognition is in its infancy and evolving at very fast pace, so new language
must be evolvable.
This is the first interation of NaiBoli and certainly not complete and very accurate. NaiBoli is a
work in the progress.
Enough fluff. Let start the real stuff.
NaiBoli divides notations/symbols into following types
•
Aadhar (आधार - Base) elements
•
Tulika (तू लका - Brush) elements
•
Chaal (चाल - Action) elements
•
Rupantran ( पांतरण - Transformation) elements
•
Parinami (प रणामी - Resultant) elements
Aadhar elements denote something on which action will take place. In future, more elements
are expected like 3 dimensional spaces to cater Microsoft Kinect or Oura, occult, wrist
band/watch, ring, glasses like google glass, etc.

Wrist Wearable
3 Dimensional Space

Microsoft Kinect,
LeapMotion, and
other gaming devices)

2. devices
Ring (smarty ring, ring
with three dots – I am
not able to recall its
name)
Tulika elements denotes thing which makes gesture. It can be finger, stylus, eye, or any other
body part or equipment.

3. Chaal elements denote action.
Movement in a
direction (swipe using
finger/s, palm, and
stylus) (At par with
Tulika elements)
Movement with
pressure in a
direction (drag in case
of finger, palm, and
stylus) (At par with
Tulika elements)
Movement in
opposing direction inward (Pinch in using
fingers)
Movement in
opposing direction outward(Pinch out
using fingers)
Rupantran elements apply transformation on Tulika elements and add context to it. Rupantran
elements also represent actions like drag or swipe.
There are following classes of Rupantran elements.
•
•
•
•
•
Class 1: Applied to a Tulika element only at a given point of time. These elements may
attach with a Tulika element as sub script.
Class 2: Applied to multiple Tulika elements. These elements glue two Tulika elements.
Class 3: Applied to a Chaal element at a given point of time. These elements transform
Chaal elements.
Class 4: Applied to Aadhar elements. These elements to be shown out of boundary of
device.
Class 5: Applied to Tulika as well as Chaal elements.
Rupantran Class 1 elements
No or Not (sub script
to a Tulika element)
Finger (sub script to a
Tulika element)

Parinami elements are resultant of application of Rupantran elements on Aadhar, Tulika or
Chaal elements. Let’s explore some of the examples of Parinami elements
