Neo-Luna Specifications & Features

Neo-Luna Navigation & Game System Overview

Luna is a High-Performance, Asynchronous, Bio-Mechanical Sensor-Fusion Position and Navigation App for iPhone — designed for multimodal interactive use in fast and dynamic environmental scenarios when vision is limited by environmental, task, personal, or other sensory-limiting factors. Neo is a Patent-Pending, High-Performance, Bluetooth BLE, Bio-Mechanical Force-Feedback Controller that pairs with Luna for fast and precise orientation updating under demanding and dynamic navigation scenarios and environmental conditions. The Neo-Luna Navigation & Game System provides a robust and intuitive navigation and control experience for tactical navigators who want to achieve a higher degree of spatial awareness, feedback, and control.

Luna Map Specification

A Luna Map consists of a .json text file type, which is easily readable and writable with any text editor, it can be easily scriptable for inter-compatibility between pre-existing maps and databases; it is compact, portable, and sharable; plus it’s forward-compatible to accommodate future planned features, uses, devices, and applications. A Luna Map consists of at least one Route with at least one Waypoint. Luna Maps are selected and loaded through the iOS File System and/or iCloud, and can be shared using built-in iOS file sharing, such as through Messages and AirDrop. Plus, Luna Maps can be organized (e.g., using Tags) and stored (e.g., on iCloud) like any file in iOS for enhanced accessibility, flexibility, convenience, and security.

Here is a Luna Map consisting of routes and waypoints within a county park dog-exercise area: dog_park_ghostball.json. Follow the formatting to create and edit your own personal and sharable maps.

Luna Navigator Properties

Luna Display

The Luna display features colored text over a black background for maintaining visual adaptation to the environment and battery conservation. Plus Luna is designed to send feedback signals to the Neo Controller, which eliminates retinal screen fatigue and further extends the battery life of your iPhone while navigating.

Luna displays only essential information for position and navigation, and is specifically designed to keep your eyes adapted to your environment instead of a bright screen — providing a tactical visual advantage in perceptually-challenging environments and circumstances.

Luna Inputs

Map Button & Route Selector

The Map button allows you to load personal and shared maps using the built-in iOS file system. The Route Selector allows you to scroll through and select routes from the currently loaded map.

Luna Outputs

Attitude: Heading, Latitude & Longitude

The Attitude Properties (Heading, Latitude & Longitude) show the iPhone’s current location and orientation relative to the Globe. Heading updates at 10 Hz, and Coordinates (Latitude & Longitude) update at 1 Hz.

Navigation: Pointer, Distance & Bearing

The Navigation Properties (Pointer, Distance & Bearing) report the current shortest (geodesic) path to the next waypoint. Pointer shows the iPhone’s angle relative to the next waypoint in degrees (i.e., Bearing minus Heading, -180 to +180 degrees). Pointer and Bearing are shown in degrees, and Distance is shown in meters. Angles are updated at 10 Hz, and Distance updates at 1 Hz.

Vibration: On-Point

Luna vibrates On-Point (±3 Degrees) for classic/traditional/compact/discreet assisted navigation without the optional Neo Controller. Since Luna uses built-in vibration, the user receives 100 samples per minute (equal to 1.67 Hz) vibration-feedback with Luna alone. When the optional Neo Controller is switched on, Luna stops vibrating-on-point, and Neo provides super-fast and enhanced feedback to the user.

Neo Controller Overview

The Patent-Pending Neo Controller is a high-performance bio-mechanical feedback device that delivers fast and sensitive force-feedback and control to the user. Whereas Luna’s vibration mode provides roughly 1.67 bits of information per second, Neo’s Patent Pending force-feedback control signal is 6 times faster and 6 times more sensitive, with 5 times more dynamic range and 4 times the magnification.

Neo’s Force-Feedback vs. Luna’s Classic On-Point-Vibration

  • 6 x Speed Increase
  • 6 x Angular Sensitivity
  • 5 x Dynamic Range
  • 4 x Magnification

Neo is 6 times faster and provides 30 times more detail compared to vibration. Simply put, Neo provides 180 times more information, every second, to the user compared to Luna’s classic vibration-on-point navigation mode.

180 times more bandwidth equates to huge performance gains in tactical navigation situations — especially integrated over space and time — leaving other navigators looking far behind

Plus, Neo is switchable on-the-fly, so you can use Luna for normal navigation needs, and just switch on Neo whenever you want or need a tactical boost in navigation performance.

Neo Physical Characteristics

The Neo Controller is 100% Upgradable, Reclaimable, and Recyclable. A Neo Controller is an investment in your own mobility and freedom, while keeping our beautiful planet healthy and green for future generations.

Specifications, including dimensions and mechanical features are approximate and subject to change.

Shell and Control Interface Material

Polylactic acid (Polymaker PolyLite PLA, True Grey). PLA is made from corn; it is 100% reusable, 100% reclaimable, and can be incinerated to return the material back to its environmental elements: carbon, oxygen, and hydrogen.

Note: The Neo Controller Is Not Water Or Heat Resistant. Do not store The Neo Controller in hot environments such as an automobile or in environments prone to excessive heat or moisture, and do not expose Neo to rain. For Continuous, All-Weather, Amphibious, Tactical Navigation — Get a Neo Tactical Navigator Kit.

Commodity Parts

All parts in the Neo Controller are responsibly sourced commodity hardware. They can be purchased, reused, reclaimed, and/or repurposed responsibly. At Global Tactile, our ultimate product life-cycle goal is to have zero landfill, zero waste, and zero emissions — an extremely unusual and overlooked essential business practice. Our innovative product design featured in the Neo Controller is testament to our fundamental principles of responsible use, conservation, and planetary freedom.
