A close-up shot of a hand holding a dark gray rugged handheld device with a screen displaying 'COMBO' and control buttons.

Create a detailed concept image of a rugged handheld device designed for interactive theme park experiences, called the 'Combo.' The device has a compact, ergonomic rectangular shape roughly the size of a modern handheld gaming console, with slightly rounded corners and a durable, matte black or dark gray plastic casing. The front features a small, bright 1.3-inch OLED screen near the top center, displaying minimalistic icons and text. Below the screen are four context-sensitive physical buttons arranged in a diamond or linear layout, designed for quick thumb access. On the side or top edge, include a small, subtle infrared emitter and sensor pair for line-of-sight interaction. The device also has a visible RFID passive chip embedded on the back, indicated by a subtle icon or translucent window showing the chip’s location. Include a small, integrated speaker grille and a USB-C port for charging on the bottom edge. The overall look should convey robust durability with a slightly futuristic, tech-savvy aesthetic — clean lines, no flashy colors or lights, emphasizing function and simplicity. Show the device held comfortably in a person’s hand to indicate scale and ergonomics. Ver mais
