The hexagram is asked about computer tablet as a gift for your father. Certainly he does not get enjoyment from this gift, because the tablet is not given.
1) Si as Parent represents your father.
2) Shen represents enjoyment that Self line (Sacrar) hopes for his father.
3) Shen is a hidden line.
4) In this specific case (there are rules for it), Shen cannot come out.
5) If Shen was able to come out, then it would combine with Si and father would be happy playing with a tablet.
6) Although Shen cannot come out, I still interpret it (#2) but it cannot perform an interaction (#5)
