This ATM concept combines human factors research, user experience, and branding analysis to create a handicap accessible ATM designed for high traffic areas. This design embodies LG's aesthetic themes to create a wheelchair and blind-accesible ATM.
Design Research: Handicap Accessible ATM
Intuitive Interaction All "input" interaction is located on the protruding portion of the machine (insert headphones, insert card, insert cash or check) and all "output" interaction is located on the lower front facet, within arms reach (cash out, receipt out). This allows the user's hand placement to flow seamlessly throughout the process.
Blind User Interface User research suggests that most modern blind users are unable to read braille; This ATM redesign puts the controls for audio instruction in the most accessible location on the machine, on the front-most portion of the machine, one of the first touch points as any user approaches the machine. Once users read the braille on the top of the machine, they are prompted to insert the headphone jack right below.
Blind-Compatible TouchScreen This design eliminates the need for keypad buttons to compensate for blind-compatibility by incorporating braille on top of the touchscreen interface used by sighted users: the braille is embedded in the glass. This offers the blind the same quality of ergonomics, user experience, and privacy as the sighted.
Wheelchair-Accessibility The cove in the lower half of the design bases its measurements on human factors research and 2015 ADA regulations for wheelchair accessibility in ATMs. All of the controls located on the machine are within comfortable reach of handicap users and able-bodied users.
Skimming/Theft Protection This ATM concept is measured for and designed to house Diebold® brand ATM products:
Diebold's current technology allows for the design to be simple and seamless, grouping all interactions that require "inserting" and "collecting" to create an intuitive flow.
USER INTERFACE DESIGN
The simple, approachable user interface is designed with LG's aesthetic themes from both their hardware and software.
The user experience design aims to minimize hands darting back and forth, and identity/information theft.
RESEARCH: IMPORTANT CONSIDERATIONS
RESEARCH: BLIND AND VISION-IMPAIRED REHABILITATION CENTER Homestead, PA
A full-scale working model (seen above) was tested by the Blind and Vision-Impaired Rehab Center's user group in Homestead, PA. Participants were asked to approach the ATM and figure out how the interaction was supposed to work. Users ranged from those who couldn't read braille, to those who have been reading for years, to those who have never use an ATM before. Some users knew to look for a headphone jack, while others knew to feel around for instructions as to what to do.
The blind user testing further solidified the design of the machine; the angles & height were complimented by most participants.
LG VISUAL BRAND LANGUAGE
After detailed analysis of LG's aesthetic cues in their appliance line, this ATM redesign focuses on a couple themes:
Dark Grey, Brushed Metal
Slight, Subtle Curves with Rectilinear Body
Chrome Trim on Curved Edges
