Utilization of the Inkling™ for the Rey - Osterrieth Complex Figure test

　The Rey - Osterrieth Complex Figure (ROCF) test assess visual-construction abilility, visual memory and executive function. Three different methods are traditionally used to track and to record the strokes during the production of the complex figure: single pen, switching felt pens and flowcharts. The Inkling™ is an instrument which attributes are to track, to record and to save the information of every stroke depicted in a standard piece of paper. The purpose of the study is to examine the advantages and disadvantages of using the Inkling™ in the ROCF test. 66 ROCF performances were analyzed from subjects aged 6 to 86 years old. Each subject performed the ROCF test twice; first with pen switching method without flowcharts and later with the Inkling™ or viceversa. The comparison of the performances evidenced 5 characteristics: Four subjects distracted by the color of the felt pens, three subjects interfered by the switching of the felt pens, three subjects which performance was facilitated by the colors of the felt pens, nine subjects with unclear score for Fragmentation and fourteen subjects with unclear score for Planning. The advantages that the Inkling™ showed were compensation for the process of flowcharts, avoid interference, and reduce the burden of unclear scoring for Fragmentation and Planning.
