A touchscreen that works flawlessly in the office can suddenly register phantom touches in the rain, or stop reacting to your finger altogether, and with work gloves on, operation frequently fails completely. The reason lies in the underlying technology: most off-the-shelf touchscreens are tuned for a bare, dry finger. For use in the field, on a construction site, in a workshop, or in forestry and agriculture, you need either a different touch technology or an operating mode that adjusts recognition for moisture and gloves. This article explains how capacitive and resistive touchscreens work, what a rain or glove mode technically changes, what role stylus pens play, and why a switchable mode is often more practical in everyday use than a technology optimized for only one scenario.
A classic capacitive touchscreen, as found in smartphones and most consumer notebooks, detects touches through the electrical charge of the human finger. When a raindrop or a film of water lands on the display, the touch controller perceives it in much the same way as a finger, because water is also electrically conductive. The result is false touches, a "jumping" cursor, or areas that stop responding altogether because the controller cannot reliably distinguish moisture from genuine finger contact.
A glove has the opposite effect: the usually non-conductive material, textile, leather, or rubber, insulates the finger from the display, so that no charge change reaches the surface at all, or only a very weak one. A standard touchscreen frequently fails to register this minimal effect at all. Operation with gloves is then simply not possible, no matter how hard you press. For professional use outdoors, in the cold, or in environments where gloves are mandatory, this is a real problem that can only be solved with a different touch technology or an adapted operating mode.
In a capacitive touchscreen, a fine, transparent conductive grid sits above the display. When an electrically conductive object, typically the finger, touches the surface, the electric field changes at that point. The touch controller evaluates this change and calculates the touch position from it. This technology enables precise, smooth operation with several simultaneous touch points (multitouch), but by its nature only responds to conductive contact.
The design commonly used in rugged notebooks and tablets is projected capacitive touch (PCT). For the RuggON VULCAN 10X, the manufacturer's product description explicitly lists this technology with the ability to support rain and gloves: the device lists "PCT touch support rain and glove mode" as a feature. Alternatively, the same model also lists a 5-wire resistive touchscreen with an optional de-icing function, an indication that manufacturers actually let you choose between both technologies for different operating conditions, rather than committing to a single solution.
The Durabook devices in the RobustBook range also rely on capacitive touch: for the tablets Durabook R11L, R11, U11I, R8 (including GC-R8) and R10, as well as for the laptops Durabook S14I and Z14I, RobustBook offers a "replacement stylus & tether for capacitive touch" as an accessory. The fact that this accessory is available for all the models listed confirms that their touchscreens are based on capacitive technology.
A resistive touchscreen consists of two thin, conductive layers separated by a small gap. When you press on the surface, the two layers touch at that point, and the electronics measure the resulting resistance to determine the position. What matters here: this technology reacts to pressure, not to electrical conductivity. That is why a resistive touchscreen works, in principle, with any object that applies enough pressure, a bare finger just as well as a glove, a pen, or even a tool.
Within our own range, this technology is found in the Getac X500: there, an "optional pressure-sensitive (resistive) multi-touch screen" is listed as a feature. The already-mentioned RuggON VULCAN 10X also lists a 5-wire resistive touch variant as an alternative to capacitive PCT technology. The advantage of resistive touchscreens lies precisely in this insensitivity to gloves and even to moisture, as long as no continuous film of water distorts the needed pressure point. The trade-off: resistive displays generally require noticeable pressure, usually offer little multitouch functionality, and appear visually somewhat less clear than capacitive displays because of the additional layers.
Rather than switching entirely to resistive technology, many manufacturers today solve the problem in software, directly on the capacitive touchscreen: with a dedicated rain or glove mode. That such a mode exists and is explicitly named is shown by several products in our own range:
These descriptions have one thing in common: they name a distinct operating mode or a dedicated display technology that exists in addition to normal capacitive operation, not a standard touch interface that happens to also work with gloves. The underlying technical idea in most capacitive systems is a modified evaluation by the touch controller: instead of treating every charge change as a potential touch, only signals above a certain signature are accepted, while large-area, uniform signals, such as a film of water, are filtered out. This makes a signal that is weakened by a glove, but still present, usable again. Which specific threshold or algorithm individual manufacturers use for this is not documented in detail on the respective product pages. From our own range, only the fact that the listed devices carry such a mode as a feature is documented.
A look at our own comparison tables shows that a glove mode does not automatically come with every capacitive touchscreen. In the tablet comparison table, alongside the general "Touchscreen" row, present in all five models Durabook R11L, R11, U11I, R8 and R10, there is a separate row for "touchscreen mode for gloves". According to it, the Durabook U11I and the Durabook R8 have this mode, while for the Durabook R11L and R11 the table shows it as not present, and for the Durabook R10 the entry is left open. The product page of the Durabook U11I adds that "the touchscreen supports operation in the rain or with gloves".
For the laptops, the laptop comparison table shows a similar picture: touchscreens are not present on the Durabook S15, optional on the Durabook S14I, and standard on the Durabook Z14I; however, this table does not list a dedicated glove-mode row separately for laptops. Anyone who specifically needs a glove mode should therefore check whether a device has a touchscreen at all, and look specifically for this feature in the relevant comparison table or product description. "touchscreen present" and "suitable for gloves" are two different pieces of information.
Besides plain finger and glove operation, stylus pens play their own role in rugged devices. Two variants can be distinguished based on the accessories in our own range:
For the capacitive touchscreens of the Durabook models R11L, R11, U11I, R8/GC-R8, R10, S14I and Z14I, RobustBook offers a "replacement stylus & tether for capacitive touch" as an accessory for each. Such a stylus has a conductive tip that the touchscreen recognizes just like a finger. It does not replace another technology, but uses the same capacitive detection, often with a finer, more precise contact area than a finger. The tether attachment additionally ensures the stylus stays with the device and is not lost during field use.
This should be distinguished from an active digitizer, as used for example on the Fieldbook P101: its product page lists an "active digitizer" in addition to "glove-operation modes". An active digitizer works via its own electromagnetic process between the pen and the display and is independent of the capacitive touch signal. This allows finer input such as signatures or freehand notes to be captured, regardless of whether a glove mode for finger operation is active at the same time. A digitizer option is also configurable for individual Durabook tablets when selecting the display, complemented by matching accessories such as a replacement digitizer pen or an active replacement stylus. The specific availability per model and configuration is determined by the respective product page.
A touchscreen optimized exclusively for maximum precision with a bare finger delivers the best input accuracy in the office, but fails precisely when weather or protective equipment does not allow that. A purely resistive display, in turn, works reliably with gloves and is insensitive to many disturbances, but offers a noticeably different operating experience with a bare finger than a modern capacitive multitouch display in everyday use. This is exactly why several manufacturers in our own range, for example Getac X600, Getac F110 G7, Getac UX10, Getac K120, Fieldbook N80 G2, and the Durabook U11I, rely on a switchable or software-adjusted mode on the capacitive display, rather than committing permanently to a single mode of operation.
For practical use, this means: anyone who works without gloves and in dry conditions for most of the day, but occasionally has to operate the device in the rain or with protective gloves, benefits from a device that can switch between normal and adapted touch modes, rather than from a technology designed for only one of the two scenarios. On the construction site, for instance, moisture, dust, and mandatory gloves often alternate over the course of a single working day. In forestry and agriculture, moisture from the weather and gloves worn for cold or injury protection frequently occur at the same time. In the workshop, phases with clean, bare hands at the keyboard alternate with phases in which documentation is done wearing work gloves directly at the vehicle or machine. In all these scenarios, a device that can adapt to the given situation is more practical than one with a single, fixed optimum.
A simple capacitive touchscreen without a special mode generally does not reliably detect gloves, because the insulating material dampens the finger's electrical charge. Devices with a dedicated rain or glove mode, such as the Getac X600, the Fieldbook N80 G2, or the Durabook U11I in our own range, are explicitly designed for this purpose, on the other hand.
Not fundamentally. Resistive displays are less sensitive to gloves and localized pressure, but usually offer less multitouch comfort and appear visually less clear. Which technology is more suitable depends on the specific use case, as shown by the parallel listing of PCT and resistive touch on the RuggON VULCAN 10X.
No. A capacitive replacement stylus, as RobustBook offers for several Durabook models as an accessory, uses the same touch detection as a finger. An active digitizer, as listed for the Fieldbook P101, instead works via its own electromagnetic process and is designed for more precise input such as signatures.
According to the tablet comparison table, the Durabook U11I and the Durabook R8 offer a touchscreen mode for gloves; for the Durabook R11L and R11 the table shows it as not present, and for the Durabook R10 the entry is left open.
Whether a touch display works in the rain or with gloves does not depend solely on whether a touchscreen is fitted at all, but on the underlying technology and any operating mode that may be available. Capacitive touchscreens offer the best everyday operation with a bare finger, but need a dedicated mode for moisture and gloves, such as the ones found on the Getac X600, Getac F110 G7, Fieldbook N80 G2, or Durabook U11I in our own range. Resistive touchscreens, such as on the Getac X500 or as an alternative on the RuggON VULCAN 10X, work, by their nature, more independently of gloves, at the cost of other trade-offs in operating comfort and multitouch. Stylus pens, capacitive or as an active digitizer, complement both approaches with precision, but do not replace them. Anyone who switches between dry office moments and wet or glove-mandatory assignments in everyday use is usually better served by a switchable mode than by a technology optimized for only one scenario.
