Narrative:
On departure we were assigned runway heading off 31C. We received several encounters with the wake of the proceeding company aircraft; nothing major but noticeable. The company aircraft was assigned a different heading than runway heading; can't remember what it was. I started looking out the window to try and figure out why we kept running into his wake; when we should be diverging. At that time we got a chime for 2000 to 3000 ft level alert. I looked back at the instruments to find the first officer had passed through the assigned heading; by almost 70 degrees and was still in a left hand bank and about to miss the level off at 3000 ft. I told him to roll out and level off. He did not respond. I took the aircraft; leveled off and rolled into a right hand bank to get us where we needed to be. I then gave the aircraft back to first officer; and we continued without further incident. The first officer said he did not understand what the flight director was telling him. I got distracted looking for the preceding aircraft. Not a good combination. We ended up passing thru our assigned heading by 70 degrees.I mentioned the new flight director at gate. First officer did not mention he was not familiar; or uncomfortable. So; I didn't think anything of it. First officer lost situational awareness due to new flight director.

Title: Air carrier flight crew reported a track deviation occurred when the First Officer had difficulty interpreting the new flight director's guidance.
Narrative: On departure we were assigned runway heading off 31C. We received several encounters with the wake of the proceeding Company aircraft; nothing major but noticeable. The Company aircraft was assigned a different heading than runway heading; can't remember what it was. I started looking out the window to try and figure out why we kept running into his wake; when we should be diverging. At that time we got a chime for 2000 to 3000 ft level alert. I looked back at the instruments to find the FO had passed through the assigned heading; by almost 70 degrees and was still in a left hand bank and about to miss the level off at 3000 ft. I told him to roll out and level off. He did not respond. I took the aircraft; leveled off and rolled into a right hand bank to get us where we needed to be. I then gave the aircraft back to FO; and we continued without further incident. The FO said he did not understand what the flight director was telling him. I got distracted looking for the preceding aircraft. Not a good combination. We ended up passing thru our assigned heading by 70 degrees.I mentioned the new flight director at gate. FO did not mention he was not familiar; or uncomfortable. So; I didn't think anything of it. FO lost situational awareness due to new flight director.
