Proximity Sense AR vs MorseUs

Experience the world in a whole new way with Proximity Sense AR! Our innovative app uses augmented reality technology to sense the distance to objects around you and translate that information into a pattern of vibrations. Simply point your phone in front of you and let the vibrations guide you. The closer you get to an object, the more intense the vibrations become. Proximity Sense AR is perfect for exploring an environment by touch alone, and if your device has a LIDAR sensor, it can even be used to navigate in the dark. It's also a great tool for experiencing your surroundings in a unique and intuitive way. So why wait? Download Proximity Sense AR today and start exploring the world around you in a whole new way! Note, for technical reference, the vibration frequency scales down from 100 Hz to the inverse of the third power of the distance out to 4 meters, intensity is proportional to rate of change of distance, and vertical surfaces (e.g. walls) have a 4 Hz pattern overlaid on the main pattern in order to provide category information.

MorseUs supports BLE (Bluetooth Low Energy) CW Morse keyer connections for learning and practicing Morse code wirelessly. You can connect and practice CW Morse training between any iOS device running MorseUs or a Mac running the MorseDX application. MorseUs supports both iambic paddles (Type A/B) and straight keys. MorseUs includes a real-time FFT decoder that converts Morse audio tones into letters. A controllable sliding graphic display shows dits and dahs visually. In Graphic Mode, you can enable the Paddle Draw option to display iambic or straight paddle touches together with the dit/dah graphics. If no paddle input is detected, the graphic animation pauses after a short delay to save power. With the Practice feature, you can practice sending letters and words using: * Mixed text generated from entered characters * 4300 built-in common English words * 1450 Turkish words (depending on your system language) At the end of Practice Mode, achievement statistics are displayed. With the Listen Groups feature, you can practice Morse listening using selected groups of letters and words. The Q button displays a list of common Q codes. Professional keyer controls include: * Tone control * WPM adjustment * Character spacing * Iambic paddle type selection (A/B) * Paddle swap function * Keyer weight adjustment The QRM feature adds background noise for realistic CW listening practice. QRM volume can be adjusted independently from CW audio volume. If the device includes a flashlight/torch, the Light option automatically appears in the setup list. When enabled, the torch flashes according to dits and dahs. The Touch Button feature enables on-screen left and right paddle controls for iambic CW practice. When connected to another iOS or Mac device, paddle touches can also be transmitted wirelessly. If the BleTX option is enabled, you can send direct messages to another device using the Send button. If you type “show help” and press ENTER, the ESP32 programming help guide will be displayed, including Arduino sample code and wiring diagrams for the wireless MorseUs CW paddle. Additional wireless BLE keyer code examples and documentation are available on: "Bluetooth iambic CW Paddle Morse Keyer TX only" GitHub Repository.
