Human Factors
We were at FL9800m offset 6 miles right of course on the airway. We received a reroute to a random waypoint then back to the airway flight plan route. When the reroute came; the Captain was out of his seat in the bathroom. The First Officer; the flying pilot; attempted to insert the cleared waypoint into the FMS and at the same time receive a frequency change to contact a second controller. His attempt to multi task caused a spelling error for the Waypoint. The aircraft started a right turn; when it should have turned left. After contacting control; he gave a heading of 240 degrees; to the correct to the waypoint; the error was corrected in the FMS; and the controller cleared us our own Navigation to the waypoint then flight plan route. The rest of the clearance was uneventful. The Captain was briefed on the reroute issue. In this situation there were multiple threats. 1. Language Barrier 2. Clearance reroute in flight. 3. One pilot away from duty station. 4. Task saturation of remaining pilot. This threat would have been trapped with both pilots verifying and checking the reroute clearance. No further comments from ATC have been received.
