Online stores: Some providers specialize in bulk-sale of raw hardware components for multi‑touch tables, which –by virtue of economics of scale – come at a low price.Overall, the market divides into three different types of service providers: You’ll find suppliers who offer standardized products (for a marginally lower sum), but in your research you’ll also encounter those who offer full-range customization. After all, the user needs to understand exactly when to “show” something to the table.The multi-touch table market is a complex one, to say the least, and might seem confusing. In addition, from an intuitive user experience point of view, it sometimes makes more sense to recognise objects directly on the table surface.Īs optical recognition is still not very well known, it can be expected that the multitouch table will require more explanation. Disadvantages of optical object recognitionįor larger or more complex objects, optical recognition reaches its limits. Visitors are often pleasantly surprised at how fast the technology is and that it recognises a wide variety of objects from all sides without markers.Īll of these advantages make a multitouch table with optical object recognition particularly suitable for use as an autonomous, interactive information counter or as a “digital concierge” in companies. This makes the technology ideal for exhibitions and events. With no additional cost for markers, any number of objects can be quickly and easily stored in the software and associated with actions. flyers, brochures) or that the user carries with them anyway (e.g. In general, optical object recognition is best suited for printed materials that are displayed near the touch screen (e.g. The content and designations on business cards are too varied for fully automated data storage, so some manual control is still required). (Anyone hoping for fully automated data transfer to a CRM system will be disappointed. At trade fairs, for example, business cards or badges can be captured and used digitally on the touchscreen. There are also numerous applications for previously unknown objects. Due to the high flexibility of the camera used, unattractive barcodes or QR codes are only required in exceptional cases, where the camera alone has to help. The camera even recognises products and other objects based on their packaging, colour and shape. The camera then recognises these and displays the appropriate digital content on the table. For example, any number of flyers, brochures and postcards can be stored as an image file in the software. What objects does the multitouch table recognize?Ī major advantage of optical object recognition is that, with the right software, all previously trained objects can be recognised and configured actions can be triggered. It detects objects next to the touchscreen and not necessarily on the touchscreen surface itself.įor example, the camera can be installed in a niche or shelf of a multi-touch table and detect anything that is briefly held or placed there. This can be located above, below or next to the touchscreen. Optical object detection is based on a high-resolution, high-speed camera. This can enhance touchscreen applications with new input or interaction possibilities. This article focuses on optical object recognition using additional cameras. Due to the integrated camera technology, these devices are usually much larger. These detect special optical marks on the table surface. There are also systems that enable object recognition on the touchscreen surface using cameras built into the screen. Optical object recognition on multitouch tables That is, analogous to finger touches, these objects trigger multiple touches simultaneously, which are then uniquely identified in their special form. The recognition here is usually capacitive. This is often referred to as “tangible interfaces”. On the one hand, there are systems that can recognize and localize objects on the touchscreen surface. Different technologies exist for object recognition with each technology having its particular strengths and weaknesses depending on the use case. Object recognition through multitouch tables enables a variety of intuitive interactions between user and device.
