Порт Type C и Lightning — это вызов для демонстрации звука

Порт Type C и Lightning — это вызов для демонстрации звука

Создание розничной демонстрационной системы наушников становится проблемой, когда Type-C и Lightning заменят обычный порт для наушников 3,5 мм на смартфонах.

От розничных интеграторов наушников будут предъявляться некоторые жесткие требования, например:

«Можете ли вы построить порт типа C и порт Lightning на борту, чтобы принимать входы типа C и Lightning для потребителей?»

Это технически возможно, учитывая известное назначение контактов типа C и порта Lightning для аудиокомпонентов. Программа Apple MFI также открыта для розничных производителей дисплеев, таких как AOK Displays.

Но это было бы долгой головной болью для связи с лицензированием Apple MFI.

В качестве альтернативы мы могли бы использовать готовые переходные кабели типа C на 3,5 мм и Lightning на 3,5 мм.

 

 

 

 

 

 

Очевидно, что объединение P1 и P2 может поддерживать вход типа C и Lightning из новейших современных

разъемы для наушников в смартфонах.

Это все так просто? Тогда в чем же проблема, когда кабели можно приобрести в любом розничном канале?

Type-C и Apple Lightning разные

Для Type-C мы можем использовать его контакты аналогового аудиовыхода для кабельного адаптера, это не отличается от обычного кабеля от 3,5 мм до 3,5 мм, см. Следующую распиновку типа C:

Назначение контактов аудио USB Type-C

Но нам никогда бы не повезло с Apple Lightning Port, в порту Lightning нет аналогового аудиовыхода, и да, как и то, что Apple делает для всех своих продуктов, там есть коммуникационный контроллер для аудиовыхода, см. Вывод как ниже:

Назначение 8-контактного разъема Apple Lightning

Для порта Lightning это вывод цифрового сигнала на кабель адаптера, а внутри кабеля адаптера есть некоторые дополнительные схемы, включая компоненты, совместимые с ЦАП и импедансом.

Подключение кабеля Lightning к разъему 3,5 мм для пользовательского интерфейса линейного входа клиента никогда не будет таким же, как то, что у нас есть сейчас с кабелем 3,5 мм на 3,5 мм, из-за встроенной схемы внутри будет дополнительная нагрузка на линию. в порту он создает дополнительный шум перед началом музыки, а также при низкой громкости.

Как устранить дополнительный шум, вызванный схемой ЦАП, встроенной в адаптер от молнии до 3,5 мм?

1 # Измените обнаружение линейного входа на обнаружение звука

Для системы обнаружения линейного входа при подключении 3,5 мм аудио демонстратор немедленно запускает отображение изображения или повтор видео;

Но для обнаружения звука точка запуска — это не момент линейного входа, а когда обнаруживается звуковой сигнал, запуск включается.

Таким образом, пользователи поднимают трубку со вставленным линейным кабелем, они не будут слышать никаких шумов до начала музыки.

2 # Добавьте фильтр нижних частот, чтобы избавиться от лишнего шума

Как объяснено в 1 #, шум перед началом музыки уже удален, что делать, если все еще есть шум?

Бренды наушников не хотят, чтобы их пользователи слышали лишний шум!

У нас есть встроенная схема фильтра нижних частот для настройки аудиосигнала, для этой части мы можем изменить параметры конденсаторов и резисторов фильтра, чтобы избежать дополнительных шумов.

Наконец, у розничных интеграторов может возникнуть такой вопрос:

Есть ли у нас идеальный выбор, чтобы сделать систему совместимой как с разъемом 3,5 мм, типом C, так и с портом Lightning?

Ответ ДА!

Мы могли бы сделать несколько портов обнаружения линейного входа, говоря, что 2 порта 3,5 мм, один порт для определения мощности линейного входа, другой — для обнаружения аудиосигнала. А вопрос совместимости портов мы оставляем на усмотрение творческих производителей кабельных адаптеров.

 

Non-Android Touchscreen Solution: Why Preferred by Experienced Retail Integrators?

Multi-layer touch screen turntable for retail comparator display

Oday interactive touch media players are becoming more popular with widely available and commercial ARM-based commercial hardware with Android 4.4 / 5.1 / 6.1 / 7.1 where app developers can do what they want through their own retail integrators Can set up a device in a store with multiple touch screen: commercial tablet with Google Play preinstalled, download auto-launch apps and launch 7/24/365, connect to remote content management system for analytics & reporting.

These are the typical scenarios that brand owners, retailers as well as retail integrators face, in most cases everyone is happy with the results.

However, more and more experienced retail integrators are opting for non-Android interactive players. In the following application scenarios, they choose alternative interactive touch players based on the old-fashioned capacitive touchscreen video screen solution.

1 # Device Life: Retail projects are less than one year old.

2 # Cost: Tier B brands require a Tier B budget (cheap brands don’t like expensive retail hardware).

3 # No remote content update required, or retail network connection is not secure or expensive

Unfortunately, over 90% of in-store retail ad campaigns face the issues listed above, if brands (end users) do not have their own data analyst to integrate OmniChannel data, they will follow the advice -Android (offline).

The non-Android solution has a special term called “multi-layered touchscreen player”. Tiered means touch players can guide shoppers to a very deep level in the demo information tree, such as an index system in a library. Most importantly, it uses an identical multi-touch capacitive touchscreen to ensure that the user experience is not compromised. As a cost-effective retail solution, it often comes with an end-user content writer or retailer integrator who creates their own interactive software, such as a Power Point presentation; It is pure simplicity on the outside with complexity highlighted on the inside, technically, each function of the solution is divided into separate modular ones with an interface identifier and a set of parameters; Experienced retail integrators can use the text file configurator to quickly create an interactive ad program using a Windows PC. The content author also has a built-in self-correction logic check to make sure there is no error before loading the media content and syntax folder generated into the device. Auto copy over USB is enabled when downloading or updating content.

Can AOK Displays provide such a cost-effective non-Android solution?

That’s a good question, and yes, we have always provided this alternative solution for many years, and we manage to improve the solution to make it easier to install and maintain. And now we offer 10.1 to 31.5 inches in open or bezel versions.

Here is a brochure about the most popular model in this line — the 10.1 » capacitive multi-layer touch player.

And here is the documentation for the content author’s user manual.

Retail Signage projects today have different requirements, mainly in terms of cost and performance, as well as the specific flow of user interaction.

 

Making the right decision when selecting the most suitable retail point of sale equipment has become a challenge for most retail equipment manufacturers and retail furniture manufacturers before they understand the critical decision factors and available equipment options.

Tired of making decisions? Not all retail screens are the same!

Let’s say there is a project that requires the activation of a 7 » POP Video Player open frame motion sensor,

 

In fact, we are faced with at least 3 hardware options as shown below:

1 # Deluxe model No. OP7007, Specification

• 12V input,
• Decoder 1080P,
• without built-in memory,
• seamless 720P video (what is it? Click on the link)
• 350 nits IPS screen with full viewing angle;
• metal case;

2 # Economy, cheaper version OP7007

• 5V input,
• Decoder 1080P,
• without built-in memory,
• seamless 720P video,
• 350 nits IPS screen with full viewing angle;
• metal case;

3 # entry-level, model # OP7003, specification sheet

• 5V input,
• 720P decoder (no seamless video loop),
• with built-in memory 256 MB,
• TN screen with limited viewing angle;
• Plastic case;

It’s easy for us to figure out a complete list of decision factors:

>>> User experience: 1 # seamless loop or not; 2 # full or limited viewing angle;

>>> Cost: case materials, memory option, input supply voltage,

>>> Type of media decoder,

>>> Screen type;

>>> Simplicity and deployment method: SD card vs built-in memory (auto copy via USB is available for both options);

Each variable mentioned above has a specific impact on the end user, so it is always important to understand the actual requirements. Fortunately, modern agencies and retail equipment manufacturers are happy to learn to understand what they need and what they will get.

AOK Displays strives to become a solution independent provider of complete IKEA-like signage solutions. We look forward to sharing customer needs and wants, contact us today.

There have been quite a few years when retail shopper analytics have not been effective. No matter how advanced technologies we use, such as iBeacon, RFID tag, touch screen to record shopper actions in a store, shopper analytics are neither accurate nor up-to-date, if we find that the analytics is not positive we cannot improve shopping experience at the moment.

facial recognition camera for retail analytics

Today, shopper analytics is becoming a versatile technology. The biometric camera with facial recognition and built-in algorithm helps sign app developers understand shopper actions accurately and efficiently.

facial recognition retail analytics

The biometric camera module, which always consists of two cameras, one with an infrared sensor and the other with an RGB sensor, can only read real people. In this way, a retail signage system with shopper analytics can detect the presence of people and uniquely identify them, whether the shopper walks a direct step or glances quickly but does not actually stop to interact with the storefront, or simply stop. to keep in touch for a while. Through a set of predefined object templates, the system detects customer interactions with products on the shelf / lift / display table if the product is picked up or the product is taken and then put back. It can be integrated with connected displays, and it can also work independently, to improve retail analytics performance for traditional, standalone retail displays. It can work as a smart sales assistant by adding audio trigger, video trigger with preset rules, thanks to the facial recognition capability, the system understands exactly the intentions of people on the shelf, and then these preset triggers can work very well at the right time.

Here is a research paper on Buyer Analytics and Retail Audience Measurement.

This is a new era of retail vision tracking with increased customer interactivity. Thanks to Rockchip RK3288 and RK3399, their powerful GPU can do video analysis and pattern matching, calculations are very efficient and accurate, they are also the main processor for face scanning access control terminals at check-in points in China high-speed railway stations, Alipay payment terminal screens with face scanning function.

Представляем бесконтактную сенсорную кнопку «airbutton» для быстрой замены традиционных кнопок

Из-за длительного кризиса, связанного с Covid-19, покупатели предпочитают использовать кнопки, не прикасаясь к ним, поэтому мы должны предложить новое бесконтактное решение в области интерактивной розничной торговли. Мы представляем вам нашу «воздушную кнопку» на основе бесконтактного датчика (PIR) для быстрой замены традиционных кнопок в существующих интерактивных дисплеях.

Размахивая или проводя руками по воздуху (диапазон чувствительности до 10 см), 2 датчика PIR могут записывать движение руки и отправлять команды на доску медиаплеера, точно так же, как мы делаем с кнопками.

Поскольку назначение контактов и профиль установки остаются неизменными по сравнению с традиционными кнопками, наши бесконтактные сенсорные кнопки могут поддерживать замену на металлические кнопки на существующих интерактивных дисплеях розничной торговли. Розничные бренды также могут модернизировать существующие дисплеи с помощью технологии сенсорных кнопок.
